BMW & MINI PETROL TIMING CHAIN REPLACEMENT
N20 Timing Chain Kit
Nearly all BMW & MINI models are fitted with a timing chain that at some point in it’s lifetime will need replacement due to wear on the components and the chain stretching. The timing chain is a critical component that ensures your engine’s camshaft and crankshaft work in perfect sync. If it fails, it can cause severe engine damage.
A failing timing chain can give early warning signs, if you notice any of the following symptoms, it’s best to get your car checked as soon as possible:
Rattling Noise from the Engine
A loose or stretched timing chain will create a rattling noise, especially during startup. This is due to excessive slack in the chain or a failing tensioner.
Check Engine Light / Drivetrain Warning
A worn timing chain can throw engine timing out of sync, causing the check engine light or Drivetrain warning message to appear. If this is ignored it can lead to serious damage.
Rough Idling or Misfire
If your car struggles to idle smoothly or misfires while driving, a stretched timing chain could be causing incorrect valve timing.
Loss of Power or Poor Performance
A timing chain that has jumped a tooth can disrupt engine timing, leading to reduced power and efficiency.
Metal Shavings in the Oil or Oil Pressure Warning
A failing chain can wear down, leaving metal debris in the engine oil, equally, a worn timing chain can hit against the plastic guides causing broken pieces to enter the engine sump and get sucked up in the oil pickup causing oil starvation, in either case this is a serious warning sign of impending failure.
