NAPA stress the importance of timely timing chain changes

Although timing chains have a longer life compared to belts, they still need looking after. Stretched chains in PSA/MINI BMW engines have been a nightmare for many garages and owners alike for years now, and NAPA are highlighting the importance of the humble timing chain and what to look out for if it needs replacing.

Durability and replacement

Unlike timing belts that require regular replacement, timing chains are generally designed to last longer. However, they are not immune to wear and tear. Replacing them at the manufacturer’s recommended interval (typically between 80,000 and 120,000 miles) is crucial for preventing engine problems.

Signs of a failing timing chain

Several symptoms can indicate a failing timing chain, including:

  • Poor engine performance (misfires, rough idling, reduced power)
  • Difficulty starting the engine
  • Engine overheating
  • Engine noise and vibration (rattling or clicking)
  • Check engine light illumination

Causes of timing chain failure

High mileage, chain wear, tensioner failure, poor lubrication, and certain engine designs can all contribute to timing chain problems.

Replacing a timing chain

Replacing a timing chain is a complex task requiring specialised tools and knowledge. It’s recommended to seek professional help or use a timing chain kit that includes all necessary components for proper installation.
