Was tracking down oil leak that appeared to be coming from the passenger side valve cover. Started checking bolts, and the bolt closest to the firewall just spins and spins. I backed it out, and found a few fine metal strings in the threads. Looks like may have stripped the threads a bit in the head. The bolt will thread in and it feels like threads grip enough to back it out. Bolt will wiggle a bit once started, but never tightens up.
Options?? Don't really want to helicoil the aluminum head, but has anyone possibly tapped the hole a size bigger and put another bolt in it?
Did a bit more digging, may try a longer M6x1.0 bolt to see if it can grab some better threads deeper in
