    Hey guys,

    Just took my car down to the shops and when i got back i had the turbo timer on and i heard a really loud tapping noise so i opened the bonnet and the tapping is comming from the back off the engine well like the back off the plenum??? Any idea what this may be? please any help would be great!:( :)

    tell me if i need to explain better but yeah it sounds like tapping but its fast tapping.

    Tapping will be lifter noise

    knocking will be bearing noise.
    if it's fast at idle, likely lifter noise.

    Yes tapping noise is 99.99% stuck lifter(s). You should do an oil change at the least... preferably a flush and oil change to clean oil galleries, although some have had success using Nulon lifter-free product.

    and if the oil change and flush doesn't work? what then?

    plenum pull, 100kk service and lifters rebuilt or replaced while its at it! 'the Z pamper pack' :D

    Was the noise keeping time with the engine revs? Perhaps an injector freaking out?:cool:

    Have you taken off your filler cap whilst the engine is running? If it's a lifter, the noise
    level may increase if it's on that bank, or put a long screw driver against the cam covers
    and like a stethoscope, you can listen for the location of the noise.:cool:

    My engine tapping sound was the VVT gears. Try disconnecting the solinoids.

    My car is running without the VVT solinoids connected and it appears to run OK. Plus no tapping sound.

    i thought lifter sounds dont usually increase to much with revs???

    my lifters tap a little, alot of my mates put in lifter treatment (nulon) and it took theirs away, ill probably do the same... replacing your lifters can be expensive too, cant remember how much for a zed but im sure someone can.

    my advice, buy the lifter treatment, its not much... if that doesnt fix it, come back here.

    almost forgot!!!! i dont describe lifters as a tapping sound, more like a ticking... tic tic tic tic.... tic tic.... is that what you got? if so probably lifters.
