Oil In Radiator

[Jamtime]

Hey guys,

Been having an issue with my 32 GT-R getting large grease build up on my radiator cap and in my overflow bottle. Motor only has around 20,000k on since stroker rebuild. Also just been back to Gas where it was built and had head gasket replaced (at my expence), which clearly didn't fix the issue. He also checked the head for cracks and checked if the problem was the oil cooler. Apart from there being oil in the water the car runs perfectly; no missing or overheating issues.

Does anybody have any suggestions to what might cause this?

Cheers,

Jamil.

By oil cooler, are you referring to the factory oil/water heat exchanger?
