OK, fix the thread issue with the helicoil. Now having trouble with oil pan to timing chain cover gasket staying in place. Numerous attempts ending with frustration and failure. The rubber seal is being pulled into the the oil pan as I tighten the bolts. Last attempt, I carefully tighten all the bolts gradually, the gasket held it's place. I then was putting the final turn on the bolts and suddenly the gasket sucked in on the drivers side. This has been my problem five times now. I'm doing something wrong. Don't know what. Any help out there?
