    Default Oil in Spark Plug Wells

    I was took out 2 spark plugs on one side of the engine and I noticed some engine oil in my spark plug wells. Any one know where this oil is coming from? And I also noticed some engine oil in my Throttle body. Any one know where its coming from? The valve covers don't seem to be leaking,

    I'd guess plugged crankcase ventilation. Probably bad pcv valve? Excess pressure can blow out valve cover gaskets.
