i get a small knock when i start the car it sounds like when the tensioner moves a lil but i dont know.

the car gets around 15mpg now (20 before )and no power loss , the noise goes away when driving down the road. coming off park it still makes some noise though, i found small shavings in the sc oil ? but the level is ok and makes full boost 15 lbs. i got new MP tensioners springs except on the accesory tensioner which moves a lil and the belt is preety old.

what do you guys think ?:confused:
 
Thinking you might want to temporarily remove a belt or two and see if the noise goes away.

You can also try spinning the sc by hand while the belt is off - don't be confused if you feel some action in the sc, which would be the drive coupler...just find out if it you can spin it without trouble, noise, etc.

Check the lower pulley/balancer for movement and/or wobble.
