Engine Oil Pump Chain & Tensioner Kit BMW 128i 335i 528i X5 Z4 N51 N52 N54

This high-quality oil pump chain kit is essential for maintaining the lubrication system's integrity in BMW N51, N52, and N54 engines. While often overlooked compared to the primary timing chain, the oil pump drive system is critical; a failure here leads to immediate loss of oil pressure and catastrophic engine damage. Over time, the drive chain can stretch and the plastic tensioner components can wear or become brittle. This kit includes a precision-manufactured drive chain and the necessary tensioning hardware to restore factory-spec operation. Engineered to withstand the constant high-speed rotation and thermal stress inside the oil pan, this kit ensures a reliable drive for the oil pump, protecting your engine's bearings and turbochargers through consistent oil delivery.
