Hi, my 1941 chevrolet coupe makes a very strange screaming/screeching noise.
When idling, the engine sounds fine and runs smooth. But when revving the engine in neutral, this strange noise is coming (I estimate at about 1000-1500rpm), at higher revs the noise disappears.
I took the belt off and ran the engine but the noise is still there, so water pump and generator are not the problem.
Does anybody have an idea what could be the problem?
when my 50 styleline had an intermitment knock I pulled the pan to plastigage all the lower bearings, ( which checked fine) I found a small spring in the bottom of the pan. I had no idea where that came from till I rebuilt my fuel pump and found this same spring in the rebuild kit. It goes on the pump arm. the pump arm must have been flopping around at various rpms. after replacing the pump, no more knocks. never can tell what you'll find in there, besides sludge. later, bill
Just keep her well oiled and sufficient coolant and I expect it will get you home just fine.
You're in my prayers to make a adventurous and safe trip home. Yep.
Best,
Charlie
BTW: Give us a post when you get back.
BTW: The popping out of gear will likely increase in frequency. Is the gears fully meshed or is the linkage off a bit. I would investigate the before starting back. I had a 41 conv. doing that to me on the way from NC to Erie,Pa way back when. Got to where it wouldn't and couldn't be held in drive. Then second started doing the same thing. Ended up having to leave it in western PA. Got back from Erie and guy I left it with helped me pull the transmission and fix it good enough to get back to NC. Talk about adventure, I have had some with my old 41s.
