BMW Timing Chain Tensioner - INA 11317838675

Product Information

This INA timing chain tensioner is an OE-quality replacement designed to maintain pressure on the timing chain guide rail, ensuring proper chain alignment and tension throughout engine operation. Manufactured in Slovakia, it delivers the reliability expected from an original equipment supplier.

Over time, tensioners can lose effectiveness due to internal wear, resulting in slack that allows the timing chain to rattle or even skip teeth—potentially causing serious engine damage. If your BMW exhibits rattling sounds from the timing area, replacing the tensioner is a smart first step before more involved timing chain service is considered.

Common failure symptoms include:

• Rattling or Clanking Noise: Most noticeable at startup, caused by insufficient chain tension allowing metal contact.
• Check Engine Light: Timing issues due to chain slack may trigger camshaft/crankshaft correlation fault codes.
• Internal Engine Damage: In interference engines, timing chain misalignment can lead to piston and valve contact, causing significant damage.
