That makes total sense Jerry on spinning the motor with the key off but alas I've started to remove the old sole so wont get chance to try that. Thanks for the info on the sheet metal removal. I am looking forward to some postmortem testing to find the noise, will start with all the rod bearings first, thinking that is where it lives. The 235 has never been rebuilt, stock bore, so I'm going through it and giving it to a friend to go in his AD
