Title: Squeaking noise on '61 Deville engine
Post by: ZGJim on May 01, 2024, 08:30:07 PM
The engine in my '61 Coupe DeVille has a high pitched squeaking noise that seems to be coming from the front of the engine.  The squeaking starts after the engine has warmed up to normal operating temp. 
We first thought it was the water pump.  That has been rebuilt.  The pulley on the power steering pump needed to be realigned with the crank/water pump pulleys.  The belts are new and tight.

While troubleshooting the belts, while the engine was hot, we removed both belts and the squeaking was still present.  The only things moving at the front of the engine were the crank pulley and the fuel pump.  Has anyone had this noise before? 

Thanks

I have had this happen on a Chevrolet motor once. The timing cover seal wasn't lubed enough during assembly and it squeaked horribly. Not sure but it might have been because of the repair sleeve on the balancer.

Try spraying a little bit of silicone lubricant on it to see if it has any effect on the noise.
Has the engine been rebuilt recently?

I had to remove the balancer and put some grease on the lip of the seal to stop it from squeaking.

Good luck with locating the noise. Hope this helps.
