I found out during an oil change on my Westerbeke generator that I have a lot of liquid in the oil. I'm really puzzled how it's getting there. First off, I don't believe it's coolant, so I don't think the head gasket is bad. The coolant is completely full and I get about a quart more in the oil from running for 15 minutes (engine holds 3 qt.). I have attached a diagram of the water and cooling system. I just can't see how water could get into the engine. The generator fires right up and runs great. I've read threads on this issue where people are saying the water pump is bad, but the W/P or systyem on this unit is not connected to the engine in any way. Westerbeke has a note talking about water in oil from "a fault in the exhaust system attached to the engine and siphoning through the raw water cooling and into the engine". Not sure what this means? Has anyone ever had this issue and how was it fixed?
Thanks
