    help have i got a cracked manifold

    vauxhall found a clicking noise on my astra and said it was a crackshaft bearing but i didn't know bearings could click, what do they know about vauxhalls lol and bearing

    heard alot of people reporting clicking and being told on here that is a cracked manifold.

    took my heat sheld off today and couldn't see a crack but i can't get to the back off it.

    there is a black sooty substance on my month old oil filter could this have come out of a crack in the manifold? it looks like it has come from the joint between manifold and rest of exhaust it too cold to work on cars

    Easiest way to locate it is get someone to put their hand (wearing a leather glove) over the tail pipe and you'll be able to hear where it's blowing.

    top advice that, but i'f you got a soot like substance then you probably do have it blowing.

    you could prob pick one up from vauxhall your self cheaper trade club is a good thing
    they should let the car get hot b4 they test it any way
    i would say run tesco ron99
    an if poss a oil change b4 the mot
    your need 2 new gaskets one for the head an one for the down pipe
    along with new manifold studs thats why i said about £150 this will inc a few tins of oil to get the old manifold studs out
