Should have hydraulic tappets as standard? In which case no adjustment required or possible. Experienced mechanic may be able to trace the sound and suggest possible/likely causes?

Cheers,

I had a similar noise from my 1.4 Astra back in November, took it to Vauxhall was told 'They all do that sir' Mechanics seemed more interested in revving it than listening to it at idle, anyway, the car hasn't moved under it's own power since Novwember. Not that I'm trying to worry you or anything!

Check you haven't got a blowing exhaust gasket - can sound v'similar and is a common problem - and they are not difficult to change as long as the bolts have not been over tightened.....

Have you done something to offend this bloke Chris? Or is he just a muppet?
The hydraulic tappets can sometimes rattle a bit at low revs when the oil presure is low, try running a slightly thicker oil if you're that bothered but mine does this fairly regularly and I recently measured the cam lifts and they were all fine so Ive decided to live with it. The fact I'm running Rhoads followers might have something to do with it, but hey I was considering solid lifters in any case.
