    Hi everyone

    I have a mopar performance distributor, the Mallory built one that is leaking oil out of the vent holes. Took the distributor apart and can't see anything obvious except that the drain holes are completely open at the bottom.
    Anyone else ran into this problem before?

    Thanks

    I haven’t had that problem. Wonder if it’s too much crankcase pressure? And/Or are your distributor bearings/bushings worn out and oil is able to get up into your distributor? Is your PCV valve system working? That’s all I got right now. Hopefully someone else may know.

    There is a plastic disk that should be around the bushing and covers the oil holes bet it is missing, pretty common actually with the MP distribs, have them if needed,
