By: 6.9 Turbo Install By Mel Agne
Preface
In July of 1983, I took delivery of my Ford F-250, which I had
ordered from Stoner-Wade Ford in Quarryville Pennsylvania two
months prior. I was 20 years old at the time. The year 1983,
marked the first year that Ford ventured into the Diesel powered
pickup truck market, which up to that time had been the province
of General Motors somewhat successful 6.2L Diesel. The 6.2
liters’ success probably would have been better, had the
consumer base not been tainted by GM’s disastrous prior
offering, the converted 350cid gas engine which was offered in
numerous Chevy and Cadillac full size cars. Ford, sensing that the
light truck market might be prime for a Diesel pickup based on a
successful and proven engine design, turned to International
Harvester to adopt their 6.9L (420cid) to pickups over 8500lbs,
GVRW. The 6.9 was already in use by International in numerous
trucks and buses of their own construction. Ford’s sales of the
F-250 and F-350 Diesel pickups were slow initially, but grew
exponentially through the 80’s as the IH Diesel won the trust of
the buying public.
My 1983 F-250 has only 96,000 miles on it at this time, mostly due
to my babying it for all these years. Not wanting to afford a new
one, I have done my best to keep this one as good as new. I have
however, paid the price of buying early. I have endured the
advancements in injection pump, seal, and head gasket
technologies, and have had to do more repairs to an engine with
this low number of miles on it, than I would have expected.
However, a Philadelphia Ford warranty adjustment agent told my
dealer who was trying to settle a claim for me that “if he
wasn’t going to drive it any more than that, he shouldn’t have
bought a Diesel”. Maybe she was right. That, and my wife always
said it would “rot” just sitting there.
This truck is currently on its third injection pump, and I had
replaced the passenger side head gasket due to water leakage in
the late 80’s. Throughout the 90’s, the Moose Truck (as it is
so named), has been trouble free. Except for an alternator, water
pump, and some batteries, I haven’t really done anything to it.
This spring however, it became apparent that two problems were on
the horizon. One was the right head gasket, which was beginning to
leak oil at the rear, and two that the newer Power Stroke’s were
pushing me out of the way on the interstates with their huge
campers in tow. I had carefully observed the aftermarket turbo
market for some time, and sat on the fence constantly as to the
virtues of turbo charging. Thanks to Ford-Diesel.com and the
members there, I finally decided to turbo. After evaluating the
features and price of the three primary turbo kit providers, I
decided on the Hypermax unit. The main deciding factor for me was
the symmetry of the installation and the clean square mounting of
the turbo. I also liked the idea of not having a Y pipe anymore.
Regardless of the turbo considerations, I knew that the head
gaskets were going to need to be replaced as a preventative
measure if nothing else.
The following photo’s and text will be my attempt to explain how
I did it, and how you the reader might try to proceed should you
be interested in doing this kind of repair and upgrade yourself.
If you’re only reading this for the head gasket or turbo
portions, be sure to make the necessary adjustments to my
instructions when re-assembling the engine. I take no
responsibility however, for the accuracy of this information, or
the consequences of any attempt to follow in my footsteps. Make no
effort to criticize my methods. This is the way I did it, and I am
in no way suggesting this is the only way. If you prefer to do it
differently, feel free. Also note, that this is not a step-by-step
explanation. This document should be considered a companion to any
manual or plans you would use singularly. You should be warned
that I am not a professional mechanic, and that I do not in any
way consider myself an “expert”. I am a shade tree mechanic
that just happens to have a comfortable garage. This project was
done over the course of two weeks, and was not rushed. I’d like
to thank all the individuals from Ford-Diesel.com who contributed
information before and during the project.
I will offer only as much detail as is needed to generalize the
procedures, except for areas that this project concentrates on
specifically, namely the gasket replacement itself, and the turbo
install. Read this entire document several times before starting.
I HIGHLY recommend that you purchase TWO different service
manuals, and follow the best procedure from either. I found large
discrepancies between my 1983 Ford Service manual, and my 1999
Haynes Diesel Repair book.
The Tear
Down

Accessories
I always hate turning that first bolt. It can be hard to take a
perfectly good running engine and begin to do things to it that
give you nightmares, and wake you up in a cold sweat. It is an act
of faith in oneself that it is a bridge you can cross and not look
back. I don’t recommend it to the faint of heart. I also don’t
recommend it if you don’t like wallowing in antifreeze, grease,
Diesel fuel, or if you have a dislike for lower back pain, cuts
and bruises and the occasional muscle cramp. It is also probably
easier if you have a helper. I must have crawled out of the engine
compartment 250 times. Begin by removing the batteries and
draining the antifreeze. It would help if you put a rubber hose on
the end of the petcock valve. I thought I’d be a smarty and just
catch it in a pan. Too bad it hit the tie rod and sprayed all over
the place. After your bath, remove the Radiator Shroud, Fan and
Radiator, including upper and lower hoses. Getting the Fan off is
easy if you have the special tool that you need. I then removed
the Alternator, Power Steering Pump, and brackets. Remove the fuel
output line from the fuel pump, the line to the injection pump and
fuel return, and remove the Fuel Filter Mount. You will find
removing the radiator allows for standing on the frame and
steering box which contributes greatly to overall comfort during
the project.
Injection Pump
Note: You have now reached a point where rotation of the engine
crankshaft is no longer allowed. Ensure that you have done
everything to make sure that nothing turns the crank from this
point onward! Disconnect all of the glow plugs from the glow
plug harness. The connectors have a tab which must be squeezed to
remove them. Then remove the injection pump. This is done by
removing the Air Cleaner and Throttle Cable Bracket, then
loosening all 8 injector lines from their respective nozzles.
Disconnect the Fuel Return line from the top of the pump, and the
Fuel Delivery Line from the Fuel Filter Mount. Then, using a Crows
Foot wrench, loosen and remove the 90 degree fuel inlet adapter
from the end of the pump. Remove the Oil Filler neck, and remove
the 3 5/16” bolts that hold the injector gear to the pump.
Remove the 3 bolts holding the pump to the pump gear housing, and
pull the pump toward the air intake. Be sure to scribe a line
between the pump and the housing so you can keep your timing
adjusted!
Intake Manifold
Remove the intake manifold by slowly loosening the attaching bolts
a little at a time until all are loose. Note that this part
requires a torque sequence to apply, so it makes sense to
un-torque it accordingly. Once all the bolts are removed (two are
shorter than the others and are at opposite corners), gently pop
the manifold off the engine. The CDR valve will need to be pulled
out of the Valley Pan grommet on the way off. If you’re lucky,
you might find some tools that have been lost for a while laying
under your manifold. I recovered a ¼ to ½ socket adapter and a
small wrench. No telling how long they had been there!
Valley
Pan
The Valley Pan is secured in the front by a steel V shaped piece
of plate steel. The rear is held down with a unique looking nut,
which takes a ½ ” drive socket extension to unscrew. Water that
falls on the engine is drained from the Valley Pan through this
nut. The front and rear edges of the Valley Pan are sealed to the
block with Silicone. My replacement pan came with special sealant
and very specific instructions on how to apply it. Be sure to use
a new Valley Pan, and follow the instructions that come with it
when you re-assemble. Note that in the photo below, that the front
retaining strap and bolts have been removed and are lying on the
pan.
Head Prep
The left and right Valve Covers come off next. Mine were
originally held on with large Phillips type bolts. I replaced
these with stainless hex head bolts some years ago. Remove
whatever type you have, and wiggle the Valve Covers off. Next,
build yourself something to keep your Push Rods and Rocker Arms
organized in. I used a pair of 2X4’s drilled to accept the
bottom end of the Push Rods, and just placed the Rocker Arms next
to them. It is important to keep the orientation and order of
these parts exactly as they come out. You do not want to install a
Push Rod upside down, or use them with the wrong cylinder, or
Rocker Arms. Imagine each piece as being unique and treat them as
such.
Note:
The manuals seem to indicate that you should put the crankshaft in
a particular position to install these things, so it would make
sense to have it that way when you remove them. I didn’t do
either, and suffered no ill effects. If you want to obey this
instruction, then make sure you set the engine up that way
earlier. You might be able to rotate it still, but I feel once the
timing gear for the pump is no longer on the pump, that turning
the crank is not what I want to do.
Remove
the bolts holding the Rocker Arms down, and lift each pair off the
head with its bracket and bolts as an assembly. Do not separate
these items. Keep them clean for re-installation with their oily
covering unchanged. The lubrication that they wear will help
protect them when you re-start. Once all of the rockers and push
rods are out, things get more serious.

Head Removal
At this point, your engine should be drained, stripped, and almost
ready to take off the heads. There are only two things you should
do first. One is, disconnect your exhaust pipe “Y” from the
Exhaust Manifolds. It is not necessary to remove the exhaust
manifolds from the heads at any time. The second thing, is to
remove the dipstick tube. THIS MAY BE THE MOST DIFFICULT PART OF
THE WHOLE JOB! I remember wrestling with the dipstick tube for 2
hours the first time I did the right head. The dipstick tube is
press-fit into the block. I can offer no sure-proof way to remove
it. I eventually got mine out by putting the tube through the hole
in the handle of a crescent wrench, and prying against the exhaust
manifold. You will need to plan on installing a new one.
A note about draining the block: Unless you remove the block
drains, you will not be able to get all of the water out. I was
afraid to mess with those things, so I used a shop-vac to suck as
much coolant out of the thermostat housing as I could. This worked
pretty well since when I removed the passenger side head, the
small amount of coolant that did spring forth, did not go into the
cylinders. I then used the shop-vac again to suck water out of the
rear block coolant passages.
There
are 18 head bolts per head. Loosen them slowly following the
torque sequence in the manual. Remove all the bolts and washers
that you can. Those in the rear that will not come out due to the
firewall, or heater core housing will need to stay in the head
until the head is removed. Make note as to which bolts these are,
since you will need them to be in the head when you re-install. I
would work on removing only one head at a time. After you have
removed all the bolts, rig a hoist to lift the head from the
engine. But first, a story.
Once
upon a time, I didn’t have a hoist, and I did this job alone
with just my arms and back. I was a lot younger then. Getting it
off, wasn’t anywhere near as hard as putting it back on. The
first time I changed my passenger side head gasket, it still
leaked when I was all done. I ended up taking it to the Ford
dealer to let them re-do it. This was my fear that I might fail
again this time. However, I took my time, had better tools, and
knowledge to use, and am glad to say I was successful. Having done
the job both ways, I would never try it again without a hoist. If
you’re going to use a hoist, take the hood off your truck as
step number one. If you’re going to use a cherry picker, or your
muscles, you could omit this step.
Rig the head for removal as shown in the picture. Remember that
the head has two alignment dowels in the form of two metal sleeves
that sit in some oil passages between the block and head. The
heads cannot be lifted straight up. They must be lifted “out and
up”. I accomplished this by lifting with the hoist, until the
motor and truck started to move. I then beat on the head with a
rubber mallet while pushing the hoist “away” from the block.
The head then popped free. Note that the alignment dowels may stay
with the head or block. You will want to capture them and set them
aside.
In
case you’re curious, the big plastic cup catches the free chain
from the hoist as the head is lifted. Professionals have a fancy
leather bag to do this.

Note that the alignment dowel came out with the head. This will
need to be pulled out, and re-inserted in the block just prior to
re-assembly. I removed my Injectors and Glow Plugs after the head
was removed. You could do it before hand if you prefer. After
inspection, I recommend having the heads thoroughly checked. I
took mine to my Ford dealer and had them check the valves. They
found a cracked valve seat, which they replaced. I then had them
send the heads out for cleaning, and Magnafluxing to check for
cracks. They came back with a clean bill of health. The picture
below shows how I fastened wooden blocks to the heads to keep them
upright and safe from nicking or scratching. I also had my
injectors tested, and one of them came back as being bad, so it
was replaced with a new one. I didn’t reinstall the injectors
until the Heads, Valley Pan and Intake Manifold were back in.
While you’re waiting for your heads to come back, you might want
to throw everything you’ve taken out (except the Push Rods and
Rockers) into the parts cleaner, and give everything a good coat
of paint. I couldn’t find a good match for the original
International colors, so I chose a nice machine gray. I didn’t
use any fancy high temperature stuff, I just went with good old
Rustoleum. It probably wouldn’t hurt to use the high temp stuff,
but I used what I had. So far, its all still there, and doesn’t
seem to be burning off. I also painted the heads when they came
back, but did not paint the exhaust manifolds, which remained
attached. When I painted the heads, I used the valve covers as a
protective lid and put tape over the intake ports, and put paper
towels in the injector holes. I used an old glow plug to cover the
glow plug hole, the bad injector to cover the injector hole, and I
just moved them from cylinder to cylinder as I painted that area.
When I painted the fuel filter stand, I left the old filter on,
knowing that I would be replacing it during re-assembly.
Putting
It Back Together
Surface
Preparation and Head Gaskets
The biggest difference between my Ford shop manual, and the Haynes
manual, was the paragraphs devoted to the discussion of surface
preparation prior to installation of the head gaskets. The
difference was, the Haynes manual had one. The Ford shop manual
didn’t! I attribute the lack of knowledge about surface
preparation and the lack of the Haynes manual to my earlier head
gasket replacement failure that I spoke of earlier. Perhaps
because the Ford shop manual was intended for professionals, they
assume that all mechanics know about such things, but alas I did
not. So, for the benefit of all I’ll simply state that the block
and head mating surfaces must be squeaky clean, and totally free
of all old gasket material. I labored for several hours cleaning
the block deck with Lacquer thinner and scraping off old gasket
material with a single edged razor blade. I went so far as to
insure that not even a fingerprint remained on either when it was
time to put the gasket in. Which is a good segue to the topic of
gaskets. I researched this a fair amount on the Ford-Diesel.com
web site, and while Felpro gaskets seemed highly rated, I decided
to get mine from the Ford parts counter. The Ford part is a nice
box that says Ford on it, and once opened contains two virgin
International service parts, still in their International service
part shrink-wrap cardboard containers. Knowing this, I would have
certainly saved a few dollars by going to IH, but since I get my
Ford parts at a discount I suppose it didn’t make much
difference. There have been a few changes to this head gasket
design over the years. The pictures below tell the tale.
The original 1983 gasket did not have any rubber grommets of any
kind. This led to early failures in the form of external water
leaks thanks deformation of the passageways.
In response to the problems imposed by the original design, rubber
grommets were introduced around 1988 in the water and oil
passageways to correct the leaks. Almost.
Over time, the rubber gasket on the oil passage broke down and got
mushy. This allowed oil to leak externally, and probably degraded
the gasket itself over time. So, the third and last revision
reverts the oil passage to a non-rubber passageway, while
retaining the useful and working rubber water passage grommets.
In addition to cleaning the surfaces, attention must be paid to
the head bolt holes in the block. Since this is a Turbo Charger
install project, the head bolts will be torqued on installation to
the non-factory setting of 85 foot pounds, which is 10 pounds more
than the manual recommends. Two things to keep in mind on this.
First, is that the threads on both the bolt and the hole need to
be clean with no rust or debris. I chased the threads in the block
with a tap several times to clean them out. I oiled the tap each
time to make the dirt stick to the tap. Since I was using new head
bolts, I didn’t worry about them too much. I visually inspected
each one and they appeared to be good to go. Secondly, since I’m
to over-torque these, I wanted to make sure my torque wrench was
accurate. I sent it to Team Torque (www.teamtorque.com) to have it
calibrated. Good thing I did, because my wrench was actually about
15 pounds higher than what the setting on it said. I doubt very
much if my head bolts would have made it to 100 pounds. They are a
tad wimpy, being only 7/16” in diameter, and you will find that
pressing them to 85 pounds will make you feel that they will snap
at any minute. But I digress. Do the taping before you do the
cleaning so there is no oil left on the block deck. Also re-insert
the alignment dowels in the block as a final step prior to
re-installing the heads. Use a shop vac to suck out any debris
from the cylinders, passageways, and bolt holes. Once your sure
everything is clean and worthy, put the head gasket on the deck
over the alignment dowels. Press the steel-cored water passage
grommets into the gasket, and lower the head on gently, trying to
match the angle of the dangle with the block. Make sure you
remember to put the head bolts and washers in the holes that you
couldn’t get out of the head when it was in the truck.
Otherwise, you won’t be able to put them in the head when it is
on. Use rubber bands to hold these difficult bolts in such a way,
that the end of the bolt is flush with the bottom of the head when
you install the head on the gasket. After the head seats on the
alignment dowels, you can remove the rubber bands, and let the
bolts drop into the block holes. I decided to use new head bolts
in this job, but there is some debate as to the necessity of this.
Frankly, even though the bolts are a tad expensive, I think
putting new ones in is worth it, since some of the old ones are
exposed to the elements in their length due to the way they pas
into the block on a chamfered edge near the exhaust manifold.
After 17 years, the ones on the drivers side had actually started
to rust through. While I did purchase new bolts, I failed to
purchase new washers. This ended up causing me grief, as one of
the washers gave out while being torqued, and ruined my torque
sequence. With help from others on the Ford-Diesel web site, I
determined that I could safely replace this single bolt after all
the others had been torqued down. Since it was Sunday at the time,
I had no way to buy a new one. Monday morning, I got one at the
International dealer and installed it without difficulty. The bolt
in question was the one on the end near the front, accessible from
outside the valve cover on the passenger side. Torque the heads to
spec using the Hypermax manual, or the picture in your service
manual. Be sure to do it at four different levels about 20 pounds
apart. The bolts and washers should be lightly oiled. DO NOT USE
NEVER SEAZE on the bolts!
Reassembly notes
Proceed to put the engine back together in reverse procedure, with
a few exceptions. Do not re-plumb the injector fuel returns
without consulting the Hypermax manual. I replaced all my T’s,
O-Rings and hoses with new. Refer to the Hypermax manual, and use
a Greenlee punch to make the 1-5/16” hole in the left valve
cover. Leave both covers off until you read my notes on the valve
covers in the Turbo Time section. Install your Push Rods and
Rockers before you put the Valley Pan on so you can watch the Push
Rod ends seat in their Hydraulic Lifters. Also, before installing
the new Valley pan, examine the area below the CDR valve drain
hole. The Hypermax installation instructions tell you to perforate
the pan to allow for better drainage from the turbo lube oil
return. I examined mine, and decided that the manufacture had
allowed plenty of drainage already, so I omitted this step with no
ill consequences. Apparently only some valley pans will require
this step due to a “manufacturing variance” to quote the
manual. Go ahead and put the rubber plug that Hypermax provides in
the back of the intake manifold before you put it on the engine.
Be sure to follow all instructions in your service manual during
re-assembly, including the torque procedure for the Intake
Manifold. At this point, we will proceed directly to the Turbo
portion of the project, so the engine accessories and radiator
will remain out for ease of access. If I were to do it over again,
I would turn up my pump BEFORE I put it back in the truck, so you
may want to do that. Again, refer to the Hypermax documentation
for instructions on that procedure.
Turbo Time!
The
Hypermax manual is really the best thing to guide you at this
point, but the purpose of this article is to point out some of the
pitfalls, and recommend what I think would be the best way to do
it. So, following roughly along with the manual, here is the order
I think it should be done.
Turbo
Installation prep
After verifying that you have all the parts necessary, begin by
modifying the drivers side Valve Cover. It will take a few minutes
to identify the parts they call the “Grommet and Baffle”.
You’re looking for the shiny metal thing that is bent into the
shape of two circles with flat edges connected together and facing
each other. The big rubber donut is the Grommet. You can confirm
you have the right pieces by fitting the Grommet into the Baffle
ring, without worrying about the Valve Cover. After you’ve found
these parts, install them in the Valve cover as per the Hypermax
instructions. If you didn’t install the rubber plug in the old
CDR valve hole behind the air intake on the Intake Manifold, you
should do that now. If you have an older truck like mine that
requires re-location of the Oil Sender unit, do that next. Valve
Cover Notes
I recommend that you use a new gasket with the valve covers. Use
Blue silicone sealer on the Valve Cover side of the gasket, and
press the gasket into the valve cover, making sure that the sealer
is contacting both surfaces all the way around. Let this material
set up for a few minutes. While it is doing so, take a rag with
some Lacquer thinner on it, and wipe down the gasket mating
surface on the top of the heads. They should be clean and free of
any old sealant or gasket material. Put the Valve Covers on then,
and install the valve cover bolts and backing plates (those
triangular things). Make sure you get the correct orientation on
the backing plates. Their job is to spread the tension across the
valve cover and they should be bowed slightly so that the center
is higher than the ends. You may need to flip them over to achieve
this direction, as after they are torqued they are lower in the
center and will have been bent this way from previous use. There
is no need for sealer on the gasket to block mating. As long as
you don’t over-torque the valve covers (7 pounds according to my
manual) they will not leak.
Getting On With It
This
was my engine at the beginning of the Turbo installation
procedure. Nice how that fresh paint makes it look eh? I should
have painted a few of the smaller parts. Oh well. This is still a
real truck, and not one of those car-show only deals. There is
really only two things that make the Hypermax turbo installation
challenging. They are the Turbo exhaust (down pipe) pipe and the
bending of the firewall flange. It seems any Turbo installation (ATS,
Banks, or what have you) requires you to mess with the firewall
flange (cab weld seam). What a pain. All I can say is do your
best. I had a particularly difficult time with this, and it is my
hope that you will make out better. Some have had success by
sawing notches in the flange and then bending the pieces over as
individual tabs. I think the tools you have at your disposal for
prying may be a big factor. I knew what I needed to do it the easy
way, but just didn’t seem to have anything shaped like what I
needed. Crowbars, big screwdrivers, saw-zalls, all these things
will be tried. The tuff part for me was getting the drivers side
pipe to clear between the bell housing and firewall flange. I had
tons of room near the bell housing, but none around the flange. I
was tempted to bend the Hypermax pipe, but ended up not doing so.
Another area that may need persuasion is the heat shield under the
passenger side floor. I discovered the down pipe was rubbing after
I had everything installed. I would recommend removing this shield
or bending it all the way against the floor before you install the
down pipe.
Speaking
of the down pipe, the Hypermax manual tells you to install this
after you install the Turbo Mounting Bracket. DO NOT DO THAT. Drop
the down pipe into place as step number one! I ended up taking the
bracket out to get the pipe in between the engine and firewall.
This will be a little like one of those Chinese torture puzzles.
You will have to get these two parts to fit in the same space, but
I think if you put the Turbo Exhaust pipe in first, you will find
it easier than doing it the way the instructions say. Mount the
Turbo Bracket next, fastening it to the passenger side head with
the 3 bolts they provide. Continue following the Hypermax
directions. The next element of torture you might encounter is
trying to tighten the bolts that hold the Turbo Charger onto the
mounting bracket. There are 4 bolts, and the two on the left are
easy. The two on the right (drivers side, we are looking from the
front now) however, are another matter. The lower right one you
can do with a 3/8” drive extension and universal joint socket.
The upper right one however, I could only do one flat at a time
with a short open-end wrench. A standard length wrench will be too
long. Another difficult task is installing the short ¼” bolt
into the exhaust pipe flange where it meets the Turbo Mount. The
pipes running from the exhaust manifolds to the Turbo must be
positioned just so, and the bolt hand-threaded into the mount
through the flange. This isn’t so tuff, however, beware. If you
have a manual transmission, there are vent holes for the clutch in
the bell housing. There is the POTENTIAL to drop one of these
little bolts into one of those vent holes. Can you say “Oh Darn?
Boys and girls?” I’d recommend stuffing a rag in those vents
to prevent such a problem. Don’t forget to pull them out later.
After mounting the Turbo, and hooking up the exhaust pipes, it is
a simple matter to install the Intake Hat, hoses and Air Cleaner
mount. I discovered that the holes used by the Air Cleaner mount,
are the holes IH uses to mount a fuel filter. It seems that the
Fuel Filter mount used by Ford is not used by IH in their own
applications. This is probably due to under the hood clearance
differences between a Ford F series pickup, and an International
S-1600 chassis. When you install the Air Cleaner mount, you may
notice that it sits on, or rubs, some of the injector lines. I
compensated for this by installing additional washers under the
Air Cleaner mount until it cleared the lines. This also helped the
air cleaner sit more level.
The
earlier versions of the Intake Hat did not have a chamfered edge
on them, and the rubber gasket, which goes over the air intake,
and beneath the hat, would be cut easily during the hat
installation. This was changed on later castings, making the
Intake Hat installation easier. In either case, be sure to coat
the rubber gasket with some oil, and ensure that the Hat seats on
the gasket, and intake properly. I found the easiest way to
install the Intake Hat, was to not worry about the orange colored
hose while putting on the Hat. I installed the orange Boost Hose
after the hat was tightened down, by removing the hose clamps, and
pushing the Boost Hose on. I then undid the clamps all the way,
and put them around the hose separately.
Hopefully
you have purchased a Pyrometer and Boost (Manifold Pressure) Gauge
to go along with your turbo installation. Hypermax provides a
mounting port on the passenger side header pipe for your
thermocouple probe. You will need to use the small pipe plug
furnished with the kit to plug this port if your not installing a
probe. The Intake Hat also has a threaded hole for your Boost
Gauge tube. I would strongly recommend filling this hole with a
Boost Gauge, and not the little pipe plug they supply. Not knowing
how much boost you’re making, is a sure way to undo all the hard
work that went into your engine. 12 pounds is max, and I would
hesitate to stray too far over 10. These are high-compression
engines, not really designed for Turbo Charging. Allow me to offer
the following letter from International that I received while
researching this project as a fair warning….
Hello
Mel,
We
are happy to hear that your truck and engine are doing so well.
Ford part number E7TZ 6051 BRM is a 6.9L head gasket kit and
Ford part number E7TZ 6051 C is a single gasket. The gasket for
the Ford application for your vintage is identical to the
International application. An International dealer will have a
head gasket as part number 1804259C6 (or C7).
I
must caution you that your 6.9 L engine block was not designed
to support a turbocharger. It would be a shame to have your
engine that has lived so long destroyed by a turbo. I don't have
specific information to share with you on this but I know we
have seen engines in reman that have been damaged beyond repair
as a result of turbocharging.
We
don't have any sales information in our office on the older
vehicles. I will ask my contacts at Ford if they have any access
to this information.
Good
luck at the next truck show!!
