Ford Taurus Forum : “oil in water”
oil in water
I have a wierd problem i actually have oil in the coolant not the other way around cant figure out whats up i have flushed the system three times and i know its not a blown head the car runs like a top doesnt miss or anything its a 95 model with the 3.8 engine in it anybody got any ideas i dont got a clue!
I believe that the crankcase ventilation system is malfunctioning.the P.C.V. valve on top of the valve cover may be plugged.There should be some kind of hose going from the valve cover (and P.C.V. valve) to the air cleaner. piston ring blowby allows combustion pressure (air) to get into the crankcase.It must find a way out . it may make its own way from the crankcase system into the cooling system.
could very well be popped head gasket, how much is in there? how often are you checking your water? a clogged PCV system will cause oil seals to leak, usually at the front or rear main, but not push oil into the water. When a head gasket blows, there's many things that go where they're not supposed to, and oil intot he water is definitly a good possibility
