I know this is a 924 board but I have a 944 S2 question. It is a 1989 944 S2 and I have oil in my coolant. I have fixed my oil cooler depth and replaced the head gasket but i am still losing allot of oil into my coolant. I lost half a quart of oil into my coolant in about 75 miles. Does any one have an idea of what the problem could be?

Did you check the head for cracks and see if it was warped while replacing the head gasket?

Same thing happened to me recently with my cheap beater car. It was a cracked head, and I didn't notice it the first time I had it off.

Imagine my disappointment when I put it back together and it was just as bad as before I took it apart. Another head from the wreckers was all it took though.

Bad enough on a 924, but a cracked head on a 944 S2 - expensive, especially for a 1st car...

Bad luck, Buddy!

Problem with the oil cooler seals or misalignment of the cooling element or relief valve. You should be able to R&R the oil cooler and fix the problem. Not too bad a job. Even though you've got the 1-piece OPRV I'd recommend using the housing alignment tool. You say you've properly shimmed the element? I'd double check that. Are you getting coolant in your oil, too? I doubt this problem is the head gasket.

I do not have coolant in my oil. where could i pick up an alignment tool and about how much does it cost. If i wanted to get the head inspected should i just pill it off and take it to any shop an ask if they can check it for warp or cracks?

Try Bruce Arnley (IIRC) at arnworx.com for the alignment tool. If I got this wrong, somebody over at www.pelicanparts.com will get it right. If you replaced your headgasket, there's no point pulling the head off again unless you have to. I'd fix the oil cooler first and go from there. Also try www.clarks-garage.com. Lots of good writeups there. And, of course, the 924S section right here!

Luck

Oil in the coolant is the cylinder head or the headgasket.

Coolant in the oil is a problem with the oil cooler seals.

You always get coolant in the oil when the oil cooler seals are the problem. So you problem is the headgasket or the cylinder head. Are you sure that the oil you are seeing is fresh, and not old oil that was not cleaned out from the incident that lead to the headgasket being replaced?

I've had coolant in the oil on a car with no oil cooler at all (hence no possibility of oil cooler seals), but a cracked head.

This same car had no oil in the coolant.

I'm not saying the problem isn't the oil cooler seals, just that failed heads and head gaskets can fail in a variety of different ways, giving different specific symptoms.

Since the head gasket has been recently replaced, this either means a crack in the head was missed (easy enough to do), the new gasket was not put in properly (we might as well assume the mechanic was competent), or some other problem.

Perhaps a leak-down test could be performed on the hot engine to see if there may be a failure in the head or head gasket, or to see if the problem lies elsewhere.

The car in question is a 944S2. Not a 2.0L engine.

The oil cooler seal failure in the 944 2.5L-3.0L family always results in coolant in the oil. The Original Poster reported oil in the coolant.

The oil cooler seals are not the problem.

I'm shaking my head here.

It has been so long since I did a cooler. I recall the oil cooler mixing both first oil in coolant and then on shut down coolant in the oil.

To settle and prevent any further potential damage to you engine. Call.

Most of the time I agree with gohim, but my experience was oil in my coolant due to a misalgined OPRV. Since 1st car says he's R&Red the oil cooler, that's why I suspected the OPRV/cooler housing. When my head gasket went bad I didn't get coolant in my oil - I got compressed fuel/air charge in my cooling system. On an '83 944.

Either way, I'd go with zuffen on this one. Have the car checked by a pro. Of course, there's a whole new can of worms - who, exactly, is a pro you can trust?
