I just finished replacing the oil separator valve. My symptoms were oil in the cylinders and from my understanding the valve can fail either open or closed, and whichever way it is it can dump oil in the cylinders. The car quite running as I was going thru a parking lot, and when I pulled the plugs they were coated with oil. So my assumption is the car dies because of no spark due to coating of oil.
My question is this, the car started right up when I was done (relief) and I had white smoke coming out of both exhaust pipes. I figured that would be the case as oil had been in the cylinders and thus down the exhaust, so the cat and muffler may be coated.
There are only three fluids that can get into the cylinder, fuel, oil, coolant, the last two not by design.
I don't think its anti freeze as it didn't smell sweat, the radiator was full when I checked it in the beginning of this job (after valve failed).
So first am I missing something? Second if it is oil, how long / how hot do you think the motor needs to get to burn off the oil. Second, besides watching the engine temp gauge anything else you would recommend while the car is running and clearing the exhaust system of oil to watch to ensure I don't do more damage?
