Car - 1999 audi 1.8 se 20v
Miles 125k
Cambelt done in last 2k alongside oil and filter change.
When car is started every time there is a rattle from the top of the engine. It goes after approx 2 to 3 seconds and car is as normal thereafter.
Mechanic said it was oil pump and has changed that and cleaned the pick up pipe BUT it still makes the same noise each and every time it is started. Noise then goes after a few seconds and car is again normal thereafter.
I can only equate the noise to when I previously did an oil change on a 2.0l 8v vauxhall engine and it took time for the tappets to be lubricated or the hydraulic tappets to sort themselves out.
Now.... Mechanic reckons it is the timing chain tensioner however I'm not sure as if that was duff then would there not be a noise most of the time.
Not sure which oil is in engine or if it has had an engine flush at service.
Any help much appreciated
Cheers

Though if you ask me, that sounds a lot like hydraulic lifters.
