[corky]

have bought 316i m40 engine,it has a tapping from rocker top just sounds like one tappet needs adjusting ,if it was camshaft would there be more than one noise thanks

iirc, m40 engines have hydraulic tappets-you cant adjust them!

Generally, from what i can remember on this site, the m40 suffers from poor oil feed to the tappets sometimes-this leads to the camshaft wearing.

This manifests itself as a tapping (generally from the end furthest from the oil feed!)

hope this helps (not too bad for an m20 driver?!)

Good Luck,
