To add to TxGoat's list of potential noise makers.........

The oil fill tube has a deflector on the end, and if the tube itself is turned a bit the crank can hit that little deflector. Like if someone tried to unscrew the fill cap, which turned the tube, instead of pulling the cap straight off. At least this is true on my 327............ask me how I know! Your oil cap should be in this orientation if your tube is in the correct position. "If" this was the source it should be easy to diagnose.




If you haven't already, go over your entire engine with your stethoscope and see if you can narrow down where the noise may be coming from. It could be coming from anywhere, and where you hear it may not be close to the actual source!

It's a rebuilt dual action pump. No tick/click using stethoscope.

It's an Ultramatic.

The oil fill tube has a mounting bracket welded on that keeps it in position.

I had the oil pump out and apart half a dozen times. I polished what I could and learned how critical the gasket thickness is. I could take my thumb and index finger and spin the pump with no binding or noise. 45 lbs at idle.

I had the distributor out, apart and polished. Worked centrifugal spring/plate until it moved smoothly. Starts advance about 600 and maxed at a little over 10 degrees.

While I do have some valve noises at idle, I do think 5E was but is not now as noisy as before I performed warm, static adjustment. I will record another video/audio of idle and post.

I think I do have an exhaust leak. It chirps loudly accelerating on the road. I bought a smoke machine for this and will use it next to test for exhaust leaks.

Is the weld on the oil fill tube factory? Is it the correct part for the engine?

Good question, I would be more inclined to think the filler tube became loose as some point and someone welded a tab on it. (When I noticed mine could move I cleaned it up and put some Loctite on it.

Parts book doesn't show a mounting tab, but who knows.
