BMW Timing Chain Guide - Febi Bilstein 11311722651

Product Information

This Febi Bilstein upper timing chain guide is a direct aftermarket replacement designed to guide the timing chain that links the camshafts in M54 engines. It ensures proper chain alignment, helping maintain precise valve timing during engine operation.

As a vital component of the engine's timing system, the guide directs the chain along its correct path, minimizing slack and vibration. It works in conjunction with the timing chain tensioner to maintain tension and prevent premature wear or misalignment of the chain system.

Typical failure symptoms include:

• Rattling or Clattering Noise: Usually heard during cold starts or idle, indicating a loose or misaligned chain.
• Engine Misfires: A slipped chain caused by a worn guide can lead to incorrect valve timing and poor combustion.
• Hard Starting or Stalling: In severe cases, engine timing may be disrupted enough to cause difficulty starting or unexpected stalling.
