Oil and water mixing

KarlC · 04-02-2010, 04:00 PM

I have a 351W punched to 396 w/ World Products heads. I have oil in water and water in oil. Came from nowhere. Replaced head and intake gaskets and same problem. Had heads checked, checked block valley and no problems found. Any thoughts or help before I pull the engine? Thanks to all who respond..........Karl
