"I just got an oil analysis back on a 1988 Hino Model 6-393N (967 Hours). They state that there is a high level of coolant in the crankcase oil. My question is besides the head gasket where else could be a source of intrusion? I noticed that the heat exchanger and exhaust manifold appear to be a one piece casting, could that also be a place to look?"
