BMW USED VANOS High-Pressure Pump - Genuine BMW 11367841784

Product Information

This oil pump provides high pressure oil for the VANOS system. This pump creates pressures up to 115BAR for VANOS system operation. A failure of this pump will cause the VANOS system to not function.

Condition: Used, tested functional. Cosmetic wear may be present consistent with normal use.

Engine Oil Pump
An engine oil pump is a critical component of a vehicle’s lubrication system. Its main job is to circulate engine oil under pressure to moving parts such as the crankshaft, bearings, camshaft, and valve train. This reduces friction, cools components, and ensures proper engine performance and longevity.

Key functions:

• Lubrication – delivers oil to reduce wear on moving parts.
• Cooling – helps carry away excess heat from engine components.
• Hydraulic support – powers systems like hydraulic lifters and variable valve timing.

Engine Oil Pump Failure Symptoms

• Low oil pressure warning light – illuminated on the dashboard due to insufficient oil flow.
• Engine overheating – oil circulation failure increases friction and heat.
• Unusual engine noises – knocking, ticking, or grinding sounds from unlubricated parts.

Other Possible Signs

• Frequent or severe engine wear (scored bearings, worn camshaft).
• Oil pressure gauge reading abnormally low or fluctuating.
• Metal shavings in oil (from insufficient lubrication).
• Complete engine failure if the pump seizes or oil starvation occurs.
