Automobile PCV valves can leak oil.
Not sure where it is on that model;it will be attached to a hose assembly to let air from the crankcase (bottom of the engine) get sucked back into the intake (top of the engine).
AnswerThe pcv value is located on the value cover next to the oil cap. The pcv value has a hose attached to it that goes from the pcv value to the bottom of the fuel injector. Once you remove this hose, the value can be easily removed with a 3/4" or 20mm wrench.Wiki User
