Hey guys, I've been fighting this issue of this "space ship" noise coming from the engine bay. I told myself over and over again that it was the UPR Smog Delete making the noise, it never crossed my mind it could be the alt. While I was putting the A/C back on the car, I had the belt off so I spun both by hand. The smog delete made no noise at all and the alt "squeaked" when I turned it by hand. The alt is a PA Performance unit, I'm guessing it's got a bad bearing in it or something. Should I just pull it off and take it to an alternator shop and let them go through it or should I send an e-mail to PA Performance about it? My exhaust is pretty quiet and the noise can be heard over the exhaust with the hood closed, etc. Opinions please.
