Oil in the water

So how difficult is it to replace oil cooler seals with the engine in the car?

A few members will tell you to remove the exhaust header for more room.

You will need the late OPRV alignment tool or you will take a chance on binding the OPRV and cause engine failure.

Since you have an 87 944 you have the new one piece OPRV and will need the o-ring and crush washer for the OPRV. Get the large bottle of SHOUT, pour half into the radiator, fill with plain water, run for 15 minutes, let cool and drain. Repeat process. After second drain, fill cooling system with plain water for a flush. Don't forget to open the heater valve so everything gets flushed. Still it is a messy job, hopefully no water got into the oil system.

Cheers,
Larry

I replaced my oil cooler seals with the engine in the car and the exhaust manifold in place. Tedious, but that is how I would do it again.

We are halfway through this project ourselves, and left the headers intact.
It is quite the rubik's cube to get the oil cooler housing back with all that hardware .
PS pump and lines were moved to afford access.
We are awaiting a Tap & Die set to re-cut the 1-piece OPRV threads..

Stopping by dealer tomorrow to pick up crush washer and O-ring.
We will be using the "Shout Treatment" of cleaning out the cooling system.
Nice tip!
Performing two oil changes in sequence to cleanse any coolant.
Oil cooler seals were original factory ... $14k of records but never done.
Avoided the milkshake... (Whew..)

thanks a ton for this forum ...

How did the threads of the OPRV get damaged? The threads in the housing are aluminum, so one would think those would be the ones that get damaged first.

I just found mine to be stripped.
I am also in the process of re-sealing the oil cooler.


And to add to the fun, the oil cooler tube that goes into the block was crunched.

Volhv,

Nice pictures.

Drscope is getting a lot of information on how it can go bad.

I see you already have another oil cooler in the background. There is a tool to check for leaks in the cooler. Buy or DIY.



The two big "O" rings on the oil cooler must be oiled or the rings will roll in the block and leak.

Be careful of the oil pressure sender wire connectors, they are hollow and brittle. They will crack easy.

Check the wire to the oil pressure sender for cracks in the insulation and path.

GL
John

I have replaced the seals on the oil cooler a few times. I don't remember if I took the exhaust off or not. I do remember it is a real trick to get the housing out. It will only come out one very exact way. After changing the seals twice and still getting oil in the coolant I realized that I needed to change the o-rings on the OPRV. I did that and it solved my problem.

Thanks for the advice John, I'll definitely do a leak check. Better to find out now than after I install it.
Looks simple enough.... The valve stem idea is genius.
