We have no problem at all if someone does not wish to pay for advice. We graciously advise them to use another site. It was the "scam" remark that didn't sit well. We all have jobs and spend a greatr deal of our free time for what amounts to "coffee money" but we save people a ton. Apology accepted. Good luck with your problem.
Just a comment on your problem. Yes, the head will have to come off. You don't want any metal chips going into the cylinder and there will be plenty by the time that problem is fixed.
