Timing Chain Replacement
How to Replace a Timing ChainYour engine has different components that need to work together at the same time for the engine to run properly. The timing chain is one such component. The timing chain is responsible for timing between the crankshaft and the camshaft. The camshaft relies on the timing chain to turn so it can drive the lifters, push rods and open and close the valves at specific times. Although the timing gears and chain are very durable, over time, the chain can stretch and the gears can wear. As a result, the valves can open and close at slightly different times causing different problems for the engine.The most common signs of a worn timing chain and gears is a rough idle, poor fuel economy, poor performance, noise from the timing chain area, and in extreme circumstances, the engine may not start. These problems can lead to more involved internal problems if the chain isn’t replaced.
