    Mmm... just like a typical V8 problem.. intake manifold... PCV/ICV valve or MAF... Now don't you forget to change that waterpump bypass tube or you are gonna have to use more Ferratrage TM in the future.

    BTW, How old is that PCV? What is the year stamped on that part?

    As far as I can tell the old one and the new part are not stamped with year of manufacturer...

    However the part numbers are radically different!

    The old one starts 1.... the new one 7...

    there should be a date somewhere on it the intake port gaskets are dated too, don't forget to do the seal between the throttle body and the intake as it's usually rock hard on the botom where the oil collects, i can't even remember how many of those i've done at this point, you don't need to pull the injectors and yes if a left side knock sensor fails you either gotta pull the water pump or the crossover pipe on the back of the heads to get the tube outta your way after you pull the damn intake again

    Tiger,
    you have to change the o-rings or the whole pipe?

    O-ring... just the o-ring. Winfred also brings up a good point on the knock sensor too.
