4.3 Merc Water In the Oil

[16christi]

Last year I noticed my 1998 Stingray's oil pressure was running a little higher than normal, but it ran fine all season. I checked the oil and saw no problems (I checked it pretty regulary)When I was winterizing it, I found the oil was very milky. Now that it is time to get it in the water, I need to fix the problem......any chance this is just a head gasket? With an auto motor, I would pressurize the radiator to determine if I had a leak - I am not sure with a boat motor. Any help is greatly appreciated.

You mean you intentionally left milky oil in your engine over the winter?<br /><br />Block off the water inlet and outlet hoses and pressurize the block.

Nope, I changed the "milky oil", but do not want to start it until I fix the problem - thanks for the tip.

Whew, had me worried there. Mostly because it happens so often.
