Belts are quieter and because of their material, less expensive to produce. Timing chains are housed within the engine and receive lubrication from engine oil and can last a long time, while timing belts are located outside of the engine and tend to dry out and crack.

How do I know if my timing chain has jumped?

Hook up the timing light to the number one cylinder and start the engine. Aim the timing light at the marks. If the timing marks do not come close to alignment or you do not see any alignment at all, it means the chain has jumped position. Locate the top of the timing chain cover.

What causes timing chain to break?

A timing chain can break with either too much or not enough tension. If the chain does not have enough tension, it can develop slack. This can result in the chain “slapping,” leading to premature fatigue. A chain with too much tension can also fail, as it is placed under excessive stress.

How do you fix a timing chain jump?

There is no easy way to correct a jumped timing belt. You will need to disassemble a portion of the engine to gain access to the belt tensioner, so you can move the belt back into position. I suggest replacing the belt and tensioners while you have it apart, so you don’t have this problem again.
