Product Information
Camshaft / Cylinder Head Component
Part number 11317835768 is a Genuine BMW component used in the cylinder head assembly. Together with camshafts, sprockets, and related hardware, it plays a vital role in engine performance by controlling valve operation. Worn or damaged camshaft components can lead to poor performance, misfires, or failure to maintain proper timing.
Genuine BMW parts meet the same stringent standards as those originally used in production, ensuring precise fitment, reliability, and long service life. These components are manufactured by BMW or trusted OE suppliers, guaranteeing factory-level quality and performance.
Engine Timing Chain
The engine timing chain is a critical element that synchronizes crankshaft and camshaft rotation. While designed to last the life of the engine, chains can wear or stretch, leading to poor performance, increased noise, and in severe cases, catastrophic engine damage if not addressed. Replacement is strongly recommended at the first sign of wear.
Engine Timing Chain Failure Symptoms
• Rattling or slapping noise from the timing area, particularly at startup or idle.
• Reduced engine performance, sluggish acceleration, or hesitation due to incorrect valve timing.
• Risk of tensioner overload, chain derailment, or engine failure if neglected.
