Over time, your engine timing components begin to wear out. Tensioners weaken, chains can stretch, and timing chain guides can wear down. All of these lead to the possibility of the timing chain jumping teeth on the sprockets, causing your timing to shift. This could result in rough idle and reduced engine power, or even complete engine failure. Prevent damage to your engine with new timing components, such as this IWIS timing chain tensioner. Note, we recommend replacing timing components every 100K miles, or sooner, depending on the condition of the timing components.

This guide is used to provide tension to the timing chain, but it wears over time. These plastic tensioners also become brittle with time and mileage, usually cracking and/or breaking completely. A common sign of worn timing chain components is noise from the timing chain area.
