    Oil in FMU? WTF

    Im getting oil in my intake so bad that it is going into my fmu. When i replaced my 19lb disc i found a glob of oil on top of the blue disc. I put in the 24lb disc and it ran like a champ for 2 days and now having the same problem, running wierd, not fast, ect. Will oil in the fmu cause chaos and will a oil seperator solve my problem?

    Do you have your valve cover vented?
    Did you plug the throttle body spacer vent?
    Anything that once was a vacuum source is now when under boost a oil spray source. You must have the engine vented or you will have leaks from the oil pan, valve covers, distributor, intake manifold. If it is vented then your passing boost past the rings.

    Guess that would help capture it till you find out why your blowing out so much oil under boost.

    Find my problem. This had to happen when I had no PCV ran and just the breather. I think i found my problem all along, a burnt mass air wire. DOH

    What does Oil in the discharge tube or anyplace else have anything to do with your MAS.

    You stated above that your MAS(MAss Air System) was your problem. Bad MAS does not cause oil in your intake tube.
