No responses yet, so I pulled the engine apart--needed a new timing chain anyhow at 65,000 miles. I had a '76 motor in storage with a lot of miles--165,000, so I robbed a lifter from it and will use just the pushrod seat and metering disc from it in the lifter in my '77. What a bummer!! The bolt that goes through the timing cover to the intake manifold (compresses the rubber seal) broke with very little wrench pressure. Now, I need to drill the old bolt out and tap a new 5/16" hole for it. Does anyone make a valley cover gasket for Pontiacs yet, or is the procedure still to use RTV gasket maker?
