Whine
So today I decided to put on a phenolic spacer to help solve the starting problem I had after the truck warms up. Get it all on crank the bad boy up and there is a horrible whine that does not go away no matter what. It seems to be coming from the drivers side so I am thinking power steering pump or alternator. I could just go get remans from the auto parts store for less than a hundred bucks but I would like to find the real problem and fix it. Anyone have any suggestions for figuring out the real culprit instead of shot gunning the problem.

Re: Whine
A quick and dirty way to find out which unit is whining is to put a long screwdriver against the part, and your ear against the handle end. A little primative, but it works pretty well.

Re: Whine
Could also remove the belts one at a time to check and see if the noise goes away.

Re: Whine
Instead of a screwdriver use a 3 foot length of old broom handle!!!

Re: Whine
If the only thing you changed was a carb spacer... I'd start by looking there, vacuum leaks can make all sorts of noises.

Re: Whine
Well I used an old broom handle I had around cause putting my head close to that rotating fan with a screwdriver seemed a bit unsafe and I ain't the most graceful joker out there. Anyway put it up against the alternator it sounds like it's full of sand and popping etc. So I'm gonna try the alternator and some new belts see if that solves it. Also seems I need to readjust the carb after adding the spacer, so got my projects for the day. Thanks for the suggestions everyone.
