What is a timing chain?
Some engines use a timing chain instead of a timing belt, to keep the valves and pistons in sync. A chain is keep behind a cover and is lubricated by the engine oil . This is why it is important that oil changes are carried out when 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 get worse if left to develop. The rattle is cause by a stretched timing chain. The only solution to this is to replace the timing chains and tensioners and the plastics guides the chain run against.
If left long enough is it possible that the tensioners will over extend and fall apart , if this happen it can cause catastrophic engine damage
