Chattering near flywheel/oilpan

Well while i was examing my voltage while the car was at idle and in neutral I noticed a stranger chatter at the bottom of my oilpan/flywheel area. The chatter sound isnt higher than the ticking lifters but it is still noticeable from about 5 feet away. It is very weird because it has a pattern to it. It chatters for about 3 seconds then stops for 1 then chatters for another 3 seconds and so on. I highly doubt rob bearings because mine were fine when I looked at them. I heard it could be an uneven flywheel? The PO had done a clutch job a little while ago. Could it be from him not getting the flywheel resurfaced? I have no idea if he did or didnt. I assume rod bearings would be a lot more noticeable and be constant rather then in a pattern.

Could it be something loose in the flywheel housing?

I heard of a stone getting in there from the timing mark opening.

That is weird.......

Could it be something from the recent starter rebuild... one of the pieces you found loose in the starter? It is open to the flywheel from the back of the starter. Did it do this before the starter install?

I guess you could uninstall the starter again and look to see that the flywheel still has all of it's teeth.

That's one of those noises you'd want to track down.

Keep us posted.

I found 2 broken looking bolts that looked like a C after they came out where the flywheel meets the starter. I dont know whats up with that. But i think i had the chattering problem before the starter.

Flywheels teeth are fine from what i can see.

How long had it been making these noises? And I assume the noise has gone away now?

Wow, someone that had been in there a lot (experienced) might be able to figure out where they came from. Or you might try to look at a used or junkyard motor to see if you could match up the bolt. Otherwise, you might just forget it, and go on.

Could this have been the cause of the starter problem?

Did you get the connections all cleaned up so that the charging system is working again?

Ohhhh... don't worry then. More than likely someone dropped a nut through the clutch inspection hole.

I agree, the nuts look exactly like they were cut from a nut splitter.

Hopefully from a long previous job.
