Does sound somehwat lifter related.

The antibleed lifters can loose oil if left compressed for some time (i.e. a fw wekeks with a cam pressing against them).

This normaly recovers reasonably quickly but, a few spirited revvings work well to get them full again.

Hi ,in mine 2.0 16v ,the noise (for 20 or 30 sec) you describe as ' it only does it the first time she is started and is fine all day long its just the first start of the day ' ,the problem was the secundary air pump with some wather inside !
She's now in the scraap ...

yea.....agree with jimmas...i have the same...changed oil - 10  40 semi synthetic - changed oil filter, but gave it an oil flush (all this recomended by my local vauxhall dealer) - it may cure it straight away but however may take a few oil changes - mine is better but still slight noise on cold start in mornings. - will change and flush oil again in about 2 or 3000 miles. - good luck with yours

I  change oil every 6 months using GM parts and 10w40 oil,, what flush would people recommend for flushing through, also is there any additives that may benefit if added to the oil???
