Here is the story. I have water in my oil on my 455 olds jet boat. I have had the heads pulled, magged, and inspected. No cracks. Had heads machined and a valve job. Replaced exaust, header, and intake gaskets. After I replaced all the gaskets and cleaned up heads, the boat ran fine 3 or 4 times with ni problems. Then i took it out and it got water in the oil again. I believe it was the intake gasket that was causing the initial leak. I took it to the mechanic and he pressure tested it and there are no leaks. Where could the water be getting into the oil. This is driving me insane, and to the poor house. Any thoughts would be greatly aprriciated.
