Omg, help. What do i do? Lock nut lost inside motor

[Guest]

Hey all. Just rebuilt motor and trans. Long story short, one of the lock nuts on #3 intake rocker backed off. Had to go down chain tunnel. No where to be found. Not in oil pan. Not sure where it could go.
Do I worry? Throw another one on and check pan again after a few hundred miles. ????

long pencil magnet with a flexi stem and go fishing all around the cam chain and the crank gear.

After lots of fishing and poking you may even knock it down and into the pan so recheck that after a while too.

Could you go looking for it with a digital inspection camera like one of these?

I wouldn't run it without finding the nut. I can't imagine the damage it could do if it got into the cam chain. Just my two cents worth ,Jerry

Removed head, pulled jugs, and oil pan. Nothing. Not sure what is under cam chain. There is a metal cup thing above the windage tray. Have poked a magnet very where I could. Anyone have a photo of cases in that area?

I know this sounds dopey.... but you did know the nut was there? Did you see it fall?

I share your pain. This is a real tough go.

If it has some even some magnetic (sometimes induced from magnetic tools - how do they get magnetised?) properties, it may have suck to the cam chain or crank cheek plate. A quick chirp on the throttle could throw it into the pan... the tenshioner would likely wipe of off....... Or it go into the trans. That'll be sudden stoppage.. very very expensive in aircraft and no fun except when sticking your finger in a Sudden Stop saw and that's still about $300 to fix.

Best wishes for a safe and speedy solution.

Found it. Trapped in guide holder under chain. Thank you Lord baby jesus.

It probably prayed just as hard you would find it
