What is a timing chain?
Some engines, particularly those in vehicles requiring an Ingenium engine service, use a timing chain instead of a timing belt to keep the valves and pistons in sync. A chain is kept behind a cover and is lubricated by the engine oil. This is why it is crucial that oil changes are carried out as recommended to prevent premature failure.
When to replace a timing chain?
The signs your timing chain needs replacing.
The first sign will be a rattle on engine start-up; this rattle will worsen if left to develop. The rattle is caused by a stretched timing chain. The only solution to this issue is to perform a timing chain replacement, which includes replacing the timing chains, tensioners, and the plastic guides the chain runs against.
If ignored long enough, it is possible for the tensioners to overextend and fail, which can lead to catastrophic engine damage, necessitating extensive vehicle engine repairs.
