I've got 2 88 subaru wagons. one with and one without turbo. I bought the turbo for some parts cheap on ebay since it was less than the pic-a-part prices. Problem is it runs great for about 5 minutes then starts getting water in oil, still runs great, though. So--- I am thinking of trying to fix it rather than just using it for parts. I suspect a bad head or gasget but am surprised it runs so good if that is what it is. I have looked at drawings in the books i have and can't see other ways for water to get into oil. I suspect it is on the return side since it does not get oil in water and the water pressure is less than the oil pressure. (maybe this explains why it runs well)
1. Is this more likely to be a bad head or a bad head gasget? ( or something else?)
2. Anyone with knowledge or ideas to tell which side it is???
3. any other thought or ideas welcome.
