well thanks for the advice fellas, didn't expect wwIII (or should that be IV

)
will change the oil and filter, an put a flush in first......if this helps, which i doubt as the oil looks fresh, then many thanks.
If it's still noisey will get tappets from vw. I did motor vehicle studies in school

, way back i know, an i remember adjusting them but not replacing, is this straight forward?
I haven't got a haynes yet either.
Cheers
