There was a period of time in the 80's & '90's when there was no valley cover gasket sold for Pontiac V8's. GM said to use RTV gasket maker, instead. I was curious whether others had the same experience. The valley cover, especially on '66 and older engines, is always a challenge to get a good seal with the gasket. Maybe RTV isn't so bad after all instead of a gasket.
The bolt that broke is the long horizontal 5/16' bolt that attaches the timing cover to intake manifold where the round water seal is located. I'm not concerned with finding a bolt, but drilling out the old one. Thank God it's easy to access.
