Look on the rear cam cover (passenger side) can't miss it. The PCV takes crankcase gasses and routes them through the intake so it will always be oily when you pull it and look at it. If the crankcase is overfilled, the crankshaft counter weights will whip the oil into a mist and then be sucked through the PCV, into the intake and burned (normal). That is why it is said that topping off the crankcase to the max mark will only exasserbate the oil consumption issue.rfishing said:After my last oil change, I checked and the level was about 3/4 inch above the max fill line. When I complained to dealer about it, they said not to worry the excess oil would be blown out the PCV and get burned. Wife drove car 2 hours long trip before getting oil corrected, and I checked the level when she got back, it was at the max line. Is it really possible oil went out the PCV?
I found oil puddled on rear of engine down in the valley below heads.

Can you be more specific about the PCV location, mine is more than likely a mess?
A photo would be great.
Coincidentally the engine started overheating afterwards.
