    What could be the reason for oil blow back into your air filter box on your 2003 Toyota Tacoma?

    No check engine light, no loss of performance. truck also throws white smoke through exhaust for a few seconds when truck is started.

    I have change the PCV valve, it did not work. This even has the Toyota tech puzzled.

    Can someone tell me if they gave me the correct PCV .
    The part number of the part they gave me is TO12204-62030

    I would appreciate any tips from you experts.

    same issues...

    I figure either sludge in the engine or the valve seals are toast.

    I Get some blue smoke on start up, i doubt it's the rings letting oil by. Probably just burnt oil from the plenum being so choked out by the oil...

    going to try the auto rx, sea foam, and atf in between oil changes.... all at once, hopefully i can clean the heart out a bit. aha, well see..:cool:
