Chevy 350 Motor that squeaks...??

Hi Guys,

I got a small block 350 motor that squeaks on the initial start up and will get louder when I rev the motor..It eventually goes away after a min or less...Any idea of what could be causing that? My old ford had the same thing...Could it be the flywheel belts? Thanks for any info...

Sometimes I think fellows come on and fabricate a problem just to see if they can get you going.

It is the belts, get this stuff called Belt Dressing and apply per the instructions.

Actually that is what a slipping alternator belt does. The belt squeal while there is a high load on the alt. and once the battery charges back up the squeal goes away. I have heard lots of people trying wd-40 for belt dressing, both are equally useless. Nothing in a spray actually fixes a mechanical problem. It might cover it up for a little while but still not fixed.

Thanks for the tip Tresi.....I don't fabricate nothing but simply ask questions to get feedback...I think this site is great and I do appreciate the insight on things I may not have a clue on...I am not mechanically smart and don't have tools to play around with things, but I do what I can...Keep on keeping on

Even WD should have made them quiet, if only for a second.

I can't believe anyone would actually recommend putting a lubricant on a drive belt!

Ummm the alternator does not vary its resistance related to electrical need - it is constant relative to rpm, no matter the load on the charging system.
