Mini Cooper Rattling Noise | Timing Chain

Are you hearing a weird rattling noise coming from your Mini Cooper? In this article we specifically address a ‘rattling noise’ that many Mini Cooper owners commonly complain about. This weird noise originates in the engine bay at the front of the vehicle. It often occurs more frequently at idle, lower speeds, and/or in colder weather. Could it be a timing chain issue?

MINI Copper Timing Chain

A timing chain is what holds all the major internal engine components together and allows them to operate in synchronism. If your MINI Cooper’s engine is rattling, this could be a result of the timing chain. Unfortunately, the timing chain support rail is made of plastic, which over time can wear down and eventually break. As this support rail begins to wear, the timing chain stretches, and the infamous rattling noise begins. If you ignore the issue, the timing chain can break and cause detrimental damage to your engine.

Avoid Rattling Noise: Prevention is Key

The best way to prevent this failure is to check your oil level regularly to ensure that it never gets low, and perform frequent oil change services, using high quality oil.
