Serp belt drive noise?
Engine was making a bad sounding noise from the front end, almost like something wrong with a cam chain. Removed the serp belt and fortunately no noise!
So I'm guessing it's something that's driven by the serp belt. Seemed like maybe the tensioner. However a few months ago I replaced the alternator could that have gone bad already? (I've had my share of new replacement parts fail in short time). The tensioner wheel is not quiet when I turn it but not so bad you'd say that it is bad. Do they still make the tensioner? Any ideas/suggestions on how to proceed with the troubleshooting?

If you need an entire tensioner assembly, let me know.

Re: Serp belt drive noise?
yes the pulley comes with the bearing. The pulley should make no noise.
I had a noise on mine a couple years ago, thought it was the tensioner, ended up being the Water Pump you can hear the noise in this clip http://vettextc.net/jeff/misc/0729091838a.mp4

Re: Serp belt drive noise?
I have a used original tensioner that came off a take-out motor. You are welcome to use it for trouble-shooting if you like. I would be glad to ship it to you if you want to give it a try.
