Hi John

It doesnt sound like the normal valve-clatter.

It sounds likesomeone tapping onthe head with a spanner.

I listened with the extensionset from the socketkeys, and it comes
from the rear exhaustvalvearea, righthandside.

Either it is a valve that hangs (broken valvespring?) I guess, or a lifter.

Any ideas on diagnose?
