Guys I have recently had the timing chain replaced from dealer and now the belt is making lots of noise, it is getting progressivly worse, goes away when I accelerate but comes back when the motor slows down. I changed the belt but the noise is still there, what is going on? is the tensioner gone? what ft lbs should it have? Is a pully off? Sometimes when I start the car it it bangs but not very often and I can never replicate it, not sure if it is the belt slapping or the starter banging out late.
