Should we start a sweepstake?
I'm with valve train. The suspense is killing me. Pull the valve covers. :-)

Diagnostic tool........

Use a mechanic's stethoscope to locate and isolate the offending noise. It could be any of the previously mentioned culprits. So you need to systematically identify the root source and cause of this problem. Keep us posted.

Really? I wouldn't necessarily have guessed that....surely they'd be witness marks in the yellow paintwork? (or are there? perhaps they're out of shot?)
