BMW Timing Chain Tensioner Upper - INA 11311738700

Product Information

This INA timing chain tensioner is an OE-grade component designed specifically for the timing chain between camshafts in BMW engines. Engineered for optimal chain tension, it ensures accurate camshaft synchronization and consistent engine performance.

Just like belts, timing chains require proper tension to keep engine components in sync. This oil-fed tensioner maintains preload on the chain, helping prevent slack that can lead to timing drift, chain slap, or catastrophic failure. INA's OE-quality construction guarantees durability and fitment to factory specs.

Failure symptoms of this camshaft chain tensioner may include:

• Rattling or Clanking Noise: Especially at cold start when oil pressure is low, caused by reduced chain tension.
• Check Engine Light: Triggered by timing discrepancies often recorded as camshaft/crankshaft correlation codes.
• Engine Damage Risk: In severe cases, incorrect timing in interference engines can cause piston and valvetrain contact, leading to internal damage.
