Timing is an essential aspect of car motor operation. One of the most important components when it comes to regulating the timing of your engine is the timing chain. While timing chains can last for a long time, they do eventually wear out. However, before they break, they usually loosen. When a timing chain is loose, several signs can help you identify a potential problem, before it becomes dangerous, costly, or both.

A simple test involving the amount of degrees you can move the crankshaft can also be a useful way of determining if you are having trouble with your timing chain. Remove the distributor cap, and turn the crankshaft, clockwise. When the rotor starts moving, stop turning the crankshaft, and read the degree meter. Note of where the rotor is, and turn the crankshaft, counterclockwise, until the rotor moves. Read the degree meter, and see how many degrees the crankshaft moved. If it is more than 10 to 15 degrees, your chain is too loose. However, these problems could also be due to worn gears or a broken tensioner.

A "Check Engine" light turning on in your vehicle may be indicate you are having a problem with your timing chain.
