Crankshaft pullys drift in and out about one quarter of an inch throwing outside belt also making noise but it doesnt sound internal

use a thread tap and a new bolt when threads are cleaned

Not a timing chain.. possibly an idler pully. possibly a power steering pump, possibly an alternator bearings.. could be adjuster pully on timing belt.. this is under the cover on the front of the motor.. get a 3 foot piece of hose put one end to your ear.. and the other end move it from item to item and listen for the sound. youi will be surprised at all the different noises your car makes.. one more thing you did not say if it was an auto or standard.. if a standard a long shot is the throw out bearing..

Replace the harmonic dampner.

wow, if the main crankshaft pulley is off, that's pretty hard to do.

but, I'll take your word for it.

I think that it's more likely that the accessories attached to the engine are not aligned to the crankshaft pulley.

Look for problems with the serpentine tensioner pulley, if you have the serpentine belt.

Look for stuck pulleys as well, that can make a belt break as the crankshaft forces the belt to try to turn the stuck pulley.

Good luck on this repair.

There is something out of alignment. look at all the pullies with belt on and engine running. use a strong flashlight to see. they all should be in alignment. if any of them are out even a little replace them. including altenator, power steering pump, a/c

it sounds belt related. i am not sure if this vehicle has a seperate belt for the ac compressor, but if so, it sounds possible that the compressor seized and tore the belt off. have a look

check all pullys for play

Could be several things. WHICH ENGINE?.. 4 cylinder (has three belts, power steering/water pump, alternator & A/C compressor, one tensioner pully A/C compressor), The V6 2.7 (has only one belt, 1 Idler pully and 1 tensioner pully), the V6 3.5 has two belts - A/C/alternator, and power steering - there are two tensioner pullys). Noises can be caused by the belt(s) themselves, pullys, bearings, pully bearings, water pump shaft bearings (or belts/pullys rubbing up against something). Let's not forget that there is also belt(s) behind the Timing Belt cover as well as pullys and bearings associated with the timing system. You could start by removing one accy drive belt at a time (alternator, water pump, compressor, power steering, etc) to see whether or not the noise goes away in each case. If after each case, you discover the noise is still there, it's probably behind the timing belt cover (idler/tensioner pully, water pump shaft bearing, crankshaft bearing, etc.). Good Luck

Take a look at the belt see if it has cracks or worn grooves.. if it dose have it replaced. if it doesn't pull on the belt back and forth see if the tension pully is giving the belt tension( it supposed to be about 1/2 of an inche to an inch or try to turn the belt around to almost half way) if not replace the tensioner pully. if good check the free pully by starting the car and spary a bit of wd40 on the center of the pully if noise disappers replace the free pully. if not see ur local auto shop..

Dear Customer,

open your bonnet than thansee you timing belt,

when you got bigger wheeled rotor nearer that you can find this pully like small colored,
