...at cam speed (two times crank speed)...
That should be "half crank speed" instead.
But we knew what you meant.;D

If the thrust bearing isn't keeping the crank in place, you can have a number of noise makersWell if we're throwing out ideas, here's one. If the chirp is sounding off at cam speed (two times crank speed) that almost HAS to narrow it down to a valve train relation.....Is there ANY chance that old or stale fuel was run through the engine? Probably far fetched I know.

Agreed Lars...
Came home from sturgeon fishing the last couple days...walked out to the shop, hit the key and it's quiet as can be...not a peep!
