NISSAN 13500-VC20A Front Timing Cover and Oil Pump Assembly

The genuine Nissan front timing cover and oil pump assembly (COVER ASSY-FRON) with part number 13500-VC20A is a critical structural component for 4.8-liter TB48 engines. This component fulfills a dual function: it seals the front of the engine block to protect the internal timing chain mechanism from external contamination, while the integrated oil pump provides the lubrication system with correct operating pressure and optimal oil circulation across the entire engine operating range.

Symptoms of Failure and Need for Replacement:

Wear to the internal components of the oil pump, scoring on the pump housing walls, or failure of the pressure relief valve can result in insufficient oil pressure, leading to accelerated wear and damage to the crankshaft bearings, connecting rod bearings, and camshafts. Other common failure symptoms include wear of the front crankshaft seal seat, oil leakage caused by warped sealing surfaces, or abnormal mechanical noise originating from the front of the engine. In the event of an engine overhaul or severe lubrication problems, replacing the complete genuine assembly is necessary to restore dependable engine operation.
