A friend has a mid 70s houseboat with Perkins 6.354t diesels. The starboard engine was a gallon + over fill in the crankcase with water, not coolant. Before doing anything to diagnose the problem he pulled the head. There was no indication of a blown head gasket and that’s when he called me. I advised him to get a oil sample, the oil had been drained but he was able to suck enough out to sample. It showed water dilution. I told him the oil cooler was a possibility and another was the exhaust manifold if it was rotted between the exhaust side and water side. Both tested good no problems. He also had the inter cooler checked and it’s ok.
I’ve run out of possible culprits, does anyone have any idea how water can get get into the oil? It didn’t happen slowly it was quick oil was ok and a week later way overfill. I can’t believe vandalism but can’t think of another way for water to contaminate the oil. Any help is greatly appreciated.
