i have a 1994 Grand Prix GTP 3.4 dohc, and i had the timing belt, tensioner pulley, idler pulleys and tensioner replaced and everything sounded fine for a week. I took the car back to have the oil pump shaft seal replaced which entailed pulling the back cams and head to replace the o-ring, and ever since i get the car back when you start the car you can hear a weird grinding noise coming from the worked on section. you can hear the noise here: https://dl.dropbox.com/u/3065306/201...2021.02.25.mov (it takes 15 sec's or so to start streaming) and also when you pull the inspection covers off the belt is WAAAY too tight it has no roll in it what soever. Any thoughts on what to look for?
