Hi everyone, this is my first post so apologies if this question has already been answered at some point - I did search the forums.
Ok, I bought an 03 plate 2.2 ecotec Astra sri a few months ago, 1 owner from new, full vx service history with 44K on the clock.
Almost from day 1, I noticed that the engine when started has a 'tick' after a few minutes of running the noise disappears completely!
Thinking that there might be a sticky hydraulic tappet that quietens after the oil has warmed and thinned I flushed the engine with winns and replaced the oil and filter, unfortunatley the noise is still present!
The noise sounds quite nasty and could I guess be compared to the sound of a knackered cam! I've had a few of them in the last 17 years of driving! owned 2 x mk2 cav 2 x mk3 Cavs & 1 x Nova all other than the Nova ate cams! but I think that was a fault that vauxhall had back then which I belive was solved by opening up the oil channels or something.
I'd really appreciate any advise.
