Am I missing...
Wondering this myself. Best I can think of is that it’s residual heat and that we didn’t get down to the teens until late in the early morning. I don’t think the temp was in the teens most of the night.
Probably this as well.
In total 4 were bent. Replaced the whole set to be sure.
But to no avail. Still makes the same noise. Has to be bottom end or balancer.
Other than over tightening rockers, what else causes push rods to get bent? Play in the cam shaft from worn out bearings?

That being said, I wouldn't expect this would keep it from firing. Mine runs fine without hooking up the vacuum advances line.

As an update, I tuned the valves and then check compression. All above 150 psi.
I pulled the side cover to inspect the rods and lifters. Lifters look fine but one of the push rods is a little bent.
This feels like I’m getting closer to the issue. Could this cause a tick? Any issue with...
