This story takes me back. I had the ol' oil-in-coolant issue and it was a PITA.

A few years ago, I had the similar oily goo in my radiator. Everyone told me it was the oil cooler rings, so I changed them. But the oil returned in the coolant.

Then I replaced the oil cooler, because I thought it might have a pin hole leak. There was no company in Los Angeles that would pressure test it for me, so I made my own. But the oil returned.

Then i replaced the oil cooler headers, because I figured it has a hairline crack somewhere that wasn't sealing up.

But the oil returned....

Then I resealed my waterpump, because maybe the four bolts that connected to the front plate might have not been properly sealed. Here's a video of why:
But the oil returned.

Then I replaced the heads and HG's on my IDI. It was a PITA in a van. Even after all that, the oil returned.

After all that, I said "F this," and swapped out the engine with my spare 6.9. After all that, I finally solved my oil-in-coolant problem. I think I had a tiny crack somewhere in the block, which allowed the oil to seep into the coolant circuit under high pressure and temp, but not the inverse. I tore down that block and used the parts for my 7.3 rebuild last year. So what started as a huge mess and pain in my butt, ended up being a great opportunity to get off my *** and build something.

Back to your situation:
I HIGHLY recommend you order a few bottles of L-11 Emulsifier which is this liquid that makes oil into thin milky liquid that is easy to drain from your coolant circuit.

The OTC coolant flushes didn't do anything on these huge IDI coolant systems. You might also want to pull the radiator and flush it because it's really hard to get all the goop out.

When you do the Oil Cooler, make sure to do it right and not pinch the rings.

Also, you should make sure your oil is crankcase oil and not tranny fluid. Your tranny lines might connect to the heat exchanger in the bottom of the radiator. I checked my goop by putting a smudge of it on a clean paper towel, and left it in the sun for a day. If the oil dried grey/black, it was engine oil. If it dried reddish, then it was tranny fluid.

@ genscripter, I have watched many of your video`s in the past and the pressing together the oil cooler several times
before my Oil Cooler leak raised up it`s ugly head.
I was wondering if one end could be pressed on at a time instead of trying to do both at the same time?
I saw this video of a guy doing it that way, but is a Power Stroke cooler but looks the same as our IDI`s.
Advance it to about 4 minutes is where he is pushing it together, goes through 10min.
https://www.youtube.com/watch?v=buBJV64vJew

I
feel for you an the chasing the oil in the coolant problem you had, Probably 90% of the "O" Ring replacements on
these old IDI`s they go together w/o any problems. It is the 10% of them with the age and years could cause a problem.
So a new replacement is wise, would not want to go through this a second time.
I came across this thread from another forum where the guy was chasing oil in the coolant similar to your`s.
7.3 oil in the coolant, o-rings, now what? - Sportsmobile Forum

I made an appointment on Monday (7th) drove down there to talk to them eye ball to eye ball since the guy would not
return my call on Friday. The guy is way cool, and seems to want to work on the newer junk and not really want to deal
with our old IDI`s. One of his mechanics did say he would take on the project. Made an appointment , but for next
Thursday the (16th).

The weather warmed up for 3days this week, be in the almost 50`s, so decided to dive in and do it my self.
I did a bunch of searching, Googling, You Tube etc... There is a ton of the Dorman Coolers out there on E-Bay with
a wide range of prices, whodathunk that? Did see one Ford dealer but wanted about $449.
Parts Geek and Rock Auto had the Motor Craft for about the same as Dorman or cheaper.

Rock Auto Cooler $303.79, Paper gaskets $3.49 and have to pay shipping. Total $350.82
Parts Geek Cooler $332.43, Paper gaskets $6.18 and free shipping, Total $344.00 But do have to pay shipping for
the gaskets which come from a different wearhouse. I did order 2 sets of gaskets in case I screwed up on one.

So I now have the old girl on the patio behind the house, removed the L/F wheel, Battery, Inner fender, unbolted
the Power Steering bracket with pump and set aside. Removed the steering Shaft.
Drained the Radiator, I just slit the lower hose so I didn`t get a bath of it splashing all over.

I used one of these pans from Home Depot, really work well and contains it all.

I
need to run over to the dump and dispose of what I drained out into their coolant waste tank. I have
2, 2 1/2 containers for the waste, so I`ll be making a few trips. Dump is only about 5 miles from here.

I know it is not tranny fluid as I have a 4-spd manual gear box.
I`ll look for that L-11 emulsifier, maybe one of the local auto parts have it.
A Mercedes Forum Iam on, guys there use Dawn to make sure the system is clean of oil, maybe I`ll
do that at the end and several flushes of Distilled water to get her squeaky clean.

I worked a couple hours this afternoon on the old girl. Thought I might flush out some of the oil etc... out of the Radiator.
The Dollar store has a product called La`s Totally Awesome, great cleaning product. really cuts through stuff. Use it when
Iam scrubbing my wheels and tires to get rid of the brake dust etc... Om my Mercedes 240D and 300D I keep the engines
pretty clean, when I get some oil leakage, spray on the Awesome, hose it off and all clean.

So I thought why not flush it down the Radiator. I mixed it 1 part Awesome and 5 parts hot water. Then poured it into the radiator
and some really nasty stuff crap drained out of the bottom. Might try it one more time before I put things back together and do
the real flush, no since having more going through the system than has to.

Drained the Oil Pan, then removed the Oil Filter. and finally got the bolts out of the Cooler.
Had to use a pry bar to break the seal and the coolant really gushed out. This is where that large pan I mentioned above really
came into play. Place it long ways with the engine under the Cooler and it will catch 99% of everything. I comes out like a Cow
pissin on a flat rock. I should have had it about 6" further back as some got on the concrete. Be sure to have plenty of Oil Soak
to throw on to soak it up along with other oil spills. Iam not talking about Cat Litter, that doesn`t really work. There is a product
that is used to soak up petroleum spills. NAPA might carry it, it`s a real fine stuff. I need to buy some more, we`ll see if they have it.

So now the cooler is hanging at an angle draining the oil out of it. Tomorrow looks like I`ll have to jack up the engine a few inches
so it clears the Manifold and frame. There is a metal piece bolted to the frame that the Brake line junctions are bolted to. If it wasn`t
there, looks like I could slide it to the rear and down.
By having the inner fender removed, you really have access to the front bolts of the Cooler.
The rear bolts can be removed from underneath.
1/2" Socket for the rears and 9/16" for the front bolts. Think I uses a Swivel (universal) and couple different length extensions.

My new cooler was suppose to be here today around 5pm, but FedEx didn`t haul it over the hill from Calif. it is sitting in their Tracy
facility. Now won`t be here till Tues. probably 5PM.

Had a couple hours this afternoon after Church to work. Removed the 2 nuts under the drivers side
engine mount, placed a 2x4 up against the Oil Pan flange at the block, and jacked up the engine a few
inches, and pulled the cooler down and out from below. Then placed a small block of wood between the
engine mount and where it sits on the frame.
I forgot, you will need to remove the 4 screws to loosen the Fan shroud when jacking up the engine.

Another storm coming in late Monday so this week will be screwed up for getting it back together.
This will give me a chance to degrease, derust some of the parts and get them painted with POR.

The Motor Craft Oil Cooler arrived this afternoon from Parts Geek. The picture they showed on their site showed
4 "O" Rings. None came in the box and it says on the box "Remanufactured". Nothing on their listing mentioned it.
Cooler did come from Ford, has their stickers on the box. Thought I was buying a new Cooler.
I sent Parts Geek a message asking them what`s up? So have to wait 24 to 48 hrs for a response.

Can`t work on the truck for a few days, we just got 4.5 inches of snow this afternoon and the rest of the week doesn`t
look too good.
