I have just done about $4500 worth of work to my truck including 2 new heads, head gaskets, ARP studs, sinister oil cooler, EGR delete and y-pipes and pretty much every gasket and o-ring on the top of that engine. So I get I back together and running and it runs great! The problem I am having is I'm getting coolant in my oil. I've already had the a shop pull the oil cooler pressure test it and check the o-rings, they said all that looks good and they said they looked at the front cover and noticed some cavitation but nothing that they said would cause my problem. I just want to know has anyone else ran into this and even if you haven't any little bit of advice I can get would be great. And by the way, I did not notice this issue before I did all this work. Thanks.
