I noticed this when I switched out the carb. I can only hear it while in park or neutral. When I'm driving and get on it a bit. Or freeway speeds, it doesn't happen. So it seems like under a load keeps it from happening. I used a thesescope?? to pin point it, seems to be the bell housing area. I am leaking oil a bit and it runs down the passenger side of the bell housing dust cover plate. And the while back half of the oil pan. Hard to tell if it's the pan seal or rear main seal. But it showed up out of no where. Could the noise cause a rear main seal to fail? If it is a loose converter would tightening it back up fix the leak?

I don't know how bolts would come lose I made sure threads were clean on both male andffemale sides and used loctite with correct torque. This noise was never present before when I first had the motor going. It only has about 700mi on it[/code]

The video works now, or did you mean the noise has been fixed? :wink:

From the video I hear something that doesn't sound right, but it's difficult to define.

Converter bolts can come loose even with the best prep. If you haven't crawled under there and checked, go there first. The oil leak may be unrelated.

It was converter noise. All bolts were a hair loose. I cleaned them all, added star lock washer and another drop of loc tite each.

I tried looking to see if leak was coming from rear main but it's just too hard to see anything from underneath. But flex plate didn't seem wet but inside bell housing is misted with oil. I tried to snug up oil pan bolts a couple were a hair out of spec. Didn't fix it. Still leaks on passenger side of the dust cover :-(

Hopefully the lock washers are really thin! Not much clearance down there! :wink:

When the motor was mated to the tranny, there should have been 2 dowel pins that stuck out maybe 1/4" from the block that the trans slides on to. Just aligning them with the bolts isn't precise enough. I had chronic problems with the flexplate > converter bolts working loose until I dropped the trans later and found out the last person installing it left them out.

Not too keen on washers there either - besides the clearance issue, if they bite into the plate that's gonna be a starting point for a stress crack. If locktite didn't do it the first time, you got other issues.

Locktite has to be applied to clean dry oil/grease free surfaces to bond properly; if not, those bolts will back out after a while. I clean threads with brake cleaner, and blow dry with compressed air.
