Hi, I have an AP1. However I could not locate the oil cooler, please help. The reason I try to find it, because I had changed the engine gasket and still have small oil leak to the radiator. Just wonder could that be a oil cooler failure.
Thx

 

It is part of the oil filter mount.

 

You screw the oil filter into it.

 

It's unlikely that your problem is coming from the oil cooler.

Did you machine your head when you replaced the gasket? If you have some slight warpage, that would cause the problem even with a new gasket.

Did you do a compression test on your cylinders? If you are getting oil in your coolant, it is possible that you have a small gasket leak at one of your cylinders. A compression/leakdown test will pinpoint the problem if it's still your head gasket.

You will also notice white smoke and misfire on cold startups, and your A/C won't seem to be working well (due to air trapped in your radiator) if you have a leak in your head gasket.
