At this point since I have the heads off I am checking the valves and giving everything a good cleaning.
When done I will have new head gaskets, LIM gaskets and a new UIM. So if there is still a leak, it should be in the radiator I would say. Am I missing any other possibilities?
The line that enters the radiator I am assuming to be an engine oil line - am I correct or is that a transmission fluid line?
