I am hoping someone can give me an easy fix for my timing cover, in which one of the self-tapping bolts decided to pull through when giving it a little torque. Of course it really was the last one to go in and the gasket sealer has since hardened. The longer story is that I bought an aftermarket supposedly OEM timing cover. The first thing that didn't happen was the dowel holes were simply too small. Secondly, the seal would not go in and stay in. Trying to get it seated correctly, it would doink and fly across the room. About the 5th time of that and I decided to put the original timing cover in. It was really not in bad condition but I wanted to get new parts in it mostly. I have thought of larger self-tapping bolts but I am still afraid to tighten. I would really rather not take all of the front apart again, but it seems the only solution, tack on a nut. Anyone else have this happen ever? BTW this is the 1968 timing cover I am working with...the one from the factory! The OEM replacement was EBAY. It was too late to return it before I even started the build. Live and learn, you get what you pay for.
