Follow-up
After weeks of searching for a mechanic that could and would work on my engine its in the shop. The mechanic called yesterday and asked me to stop by. When he dropped the pan there were aluminum pieces in the pan. They were not shavings but small pieces. There were no shims on any of the main caps. Since it was Friday he didn't want to take the caps off until Monday morning the see were the pieces came from. Any ideas I can fret over for the weekend??
