Was running with valve covers off and noticed air bubbles around head bolts? Have small video but can't seem to get it posted. Torqued them down more and seemed to stop. What am I looking at here...head gasket?

 

Guess I will torque them down and hope for the best

 

My 12v did that to me. It had about 200k on it at the time. I know the new current owner, and told him about it. It is now over 350k and still no additional problems.

 

Good to know. Thanks.
