I am going to have to assume this is a 4 cylinder with a timing chain. Probably a 22R or 22RE engine. This is not a small job. The cause of a loose chain is attributed to 1. timing chain stretch 2. the plastic guides break or wear away 3.the tensioner is no longer tensioning. The fix is to replace timing chain,chain guides, and the tensioner, while you have the vehicle apart it is GP ( general practice) to replace the front crankshaft seal as well as valve cover gasket and half moons, be sure to check your water pump as well for leakage and or bad bearings. Do a tune-up, adjust the valves and youll be good as new! Buy a Haynes or Chilton book for teardown instructions. Hope this helps ya!

I have a 1998 infiniteQ45 car bt when I turn it on it makes a Loud Clicking noise & the car is shacking & 4rm the bottom alot of the oil come out What is it tht I need 2 fix & How much will it cost me


Loosing a lot of oil is no good. if it has a very "strong " smell and is light in color it is coming from the gearbox. I suspect there is a problem whit the CV joints (the loud clicking noise when turning) and it has gone so bad in might cause the gearbox oil to start leaking. The shaking is also not a good sign. Expensive repairs unfortunately but need to be done immediately. Can loose a driveshaft causing more damage.

Loud clicking noise coming from crankshaft pulley and goes away when a/c is on and when idle is higher. Why the noise?


Take a dry bar of soap and touch it against the sides of the belt(s) while the engine is running. If the noise goes away for a little while, the noise is from the belt settling into the grove of the pulley. Belts can really make loud pooping noises.

If this has no effect, then your timing chain may be too loose for the timing chain tensioner to compensate, and the chain is slapping against the inside of the timing chain cover.

If this is the case, do not let this condition go on. The timing chain cover is aluminum, and the chain is high grade steel. The chain will wear a hole in the cover if it is hitting the inside of it, and that is allowed to continue.

Growling engine noise only at idle. Cam area


Take all of the belts off for a short run at idle. If the sound goes away it is pulley related, spin each pulley and listen for bearing noise, also check for play at this time.

If the noise does not go away when the motor is driving no accessories you have a more serious problem.
