- - Noise! (https://www.fordbarn.com/forum/showthread.php?t=95780)

Ugh! I'm trying to track down two different noises.

The first is in the engine compartment. i *think* it's coming from the distributor because when I put pressure on the dist body it temporarily went away. Although... maybe it was just a coincidence...

Here is a video of my engine running, notice the clickly clack noise that speeds up with the engine rpm. https://www.youtube.com/watch?v=FWHwUmdgtL0

The second has me seriously puzzled. When I get over 15-20 mph I can hear what sounds like a metal on metal rub. It sounds a lot like a train wheel rolling down the track.

It only starts up once I get to a certain speed
Putting the car in neutral or pressing in the clutch has no effect
Running the rear end on jack stands, there is no noise... (I did not run it at full speed).
I can rock the rear wheels back and forth (slightly) when up on jack stands.
My Passenger rear wheel had more play. So I took off the drum to inspect and replace. There was no major evidence of rubbing on the backing plate.

This car sat for 25+ years until I got it running in '99. Since then it hasn't driven more than 25-50 miles a year. in '99 I repacked all wheel bearings and replaced brake pads, etc.

Any idea where to look? I'm thinking wheel bearings / hubs..

Have you adjusted the valves? You can definitely hear some of them. That's where I would start.

Concur with that thought. But front or back? The fronts are a lot smaller - and unless the car driven extensively with very fat passengers, probably the heavier loaded. Pulling the front wheels/hubs is pretty easily done. You may have a cracked roller.

Wow those are some loud valves. Definitely need to adjust those. Then you should be able to narrow it down. What is that on the intake manifold where the wiper line goes?

Adjusting the valves sounds a bit out of my league. I might have to find someone to help.

I was wondering if anyone was going to notice that. It's just a valve I threaded into the manifold until I track down where a vacuum leak is in my wiper / tubing.

Just poured some MMO down the distributor port in the head and it quieted down a bunch.

Ck for wobble, looseness in the dist shaft. The bushings in the dist may be bad.

Check the Bushings on the dist shaft. sound to me like the problem

noise problem #2
maybe noisy speedometer cable....

UPDATE on my search for the 15-20mph noise. Popped off the drivers front hub last night and one of the rollers on the inner (larger) bearing was broken. Hoping it's going to be as simple as replacing the bearings and races in that hub.

However, I'd be concerned as to ...WHY it happened, i.e.- cheap defective replacement part; not lubed proberly; not adjusted properly..WORN HUB, etc. I'd make sure that I checked the other side also. Q: how was the adjustment situation...when you took the BO side off? Too tight/too loose adjustment is bad business,eh! No regular PM is asking for it:D

Noise coming from the distributor:

In addition to a worn out shaft and bushings, another cause could be the tip of the rotor striking one or more of the four electrical posts. Upper repo distributor caps are notorious for being of poor quality in the area of the four posts. There should be a gap between the tip of the rotor and each post between .025 and .035 (depending on personal choice). Repo caps should always be fitted to the distributor by filing the post or the tip of the rotor.

Your description of your second noise at 15 - 20 mph sounds somewhat familiar to what I have.

Have a 1930 differential that for years, at about 23 to 26 mph it sounds like a boat propeller crossing over a mound of oyster shells, (i.e., encountering a submerged oyster bed or oyster reef); however, from 22 mph down, & from 26 mph upwards, it is quiet.

Never had a speedometer in this car but I knew when I was going about 25 mph.

This will be my next differential re-build project.
