As of yesterday my car had started overheating, gauge goes all the way to the right and limp mode. I checked the coolant reservoir and there was some oil inside of it. I checked the oil cap and did not see any coolant, however upon further inspection I noticed that there was dried up coolant underneath the intake manifold and on top of the HPFP, coating the engine, looks like it was spraying out at one point. I was thinking it was the oil filter housing gasket since where it sits its somewhat possible, but doesn't explain why the car is overheating. Before I take the head off the engine and replace it can anyone tell me anything else I can check? I looked through the forums and found some on this issue but none of them also stated that their car was overheating so If anyone has had anything similar happen I'm glad to take the advice. Also the water pump runs just fine.

plug inspection, scope it and cylinder block test to verify

Have you done a compression and leak-down test yet? If not, I would start there.

Just an update on this old thread if anyone was wondering it was in fact a blown head gasket lol.
