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
