Bmw 750I Engine Oil Pump Gaskets

Bmw 750I Engine oil pump gaskets

Starting at $31.95, AutoBuffy stocks 1 engine oil pump gaskets from Elring for the Bmw 750I. The oil pump gasket seals the junction between the oil pump and the engine block, preventing pressurized oil from leaking past the mating surface. A failed gasket drops oil pressure, starves bearings and camshafts of lubrication, and can cause rapid, expensive engine damage if ignored.

Signs your Bmw 750I needs a new engine oil pump gasket

  • Oil pressure warning light illuminates at idle or during acceleration, indicating a loss of system pressure at the pump sealing surface
  • Visible oil film, seepage, or pooling at the base of the oil pump housing where it meets the engine block
  • Low oil level on the dipstick with no obvious external drip from valve covers or drain plug — oil is escaping at the pump
  • Ticking or knocking noise from the engine at startup that fades as oil pressure builds, signaling inadequate lubrication during prime
  • Oil pressure gauge reads noticeably lower than normal during warm idle, pointing to a pressure leak rather than a worn pump
  • Burning oil smell from the engine bay caused by oil contacting hot exhaust components near the front or lower block

Which engine oil pump gasket should you buy for your Bmw 750I?

The right oil pump gasket depends on the gasket material, whether you need a single gasket or a kit that includes the pickup tube O-ring and front cover seal, and whether you are doing a routine reseal or replacing a pump entirely. OE-equivalent fit and correct material thickness matter most here because the gasket must maintain a precise crush to hold oil pressure reliably.

OE-Replacement Paper/Composite Gasket
Best for
Budget-conscious repairs on standard driving vehicles with the original pump still in place
What you get
Direct factory-thickness replacement; meets original manufacturer specs for crush and sealing; typically sold as a single gasket
Molded Rubber or Rubber-Coated Steel Gasket
Best for
Higher-mileage engines or those that have seen previous oil leaks; better resistance to heat cycling
What you get
Improved conformability to slightly uneven sealing surfaces; less prone to cracking over time than paper; often reusable if undamaged during removal
Oil Pump Gasket Kit
Best for
Complete oil pump replacement or full front-of-engine reseal jobs
What you get
Includes the oil pump gasket plus pickup tube O-ring, front cover gasket, and/or crankshaft seal — eliminates repeat teardowns for missed seals
OEM / Dealer-Sourced Gasket
Best for
Owners who want exact factory material, thickness, and part number verification
What you get
Guaranteed dimensional accuracy for that specific engine family; recommended when clearances are tight or the engine is still under any remaining powertrain coverage

Replacing the engine oil pump gasket on a Bmw 750I

Advanced⏱ 2–5 hoursSocket set and ratchet (metric and SAE)Torque wrenchOil drain panGasket scraper or plastic razor bladeRTV sealant (if specified by engine manufacturer)

Accessing the oil pump gasket on most engines requires draining the oil, removing the oil pan or timing cover, and sometimes displacing the harmonic balancer or timing chain tensioner — which is why this job is rated Advanced for most Bmw 750I owners. Once the pump is exposed, the old gasket must be fully scraped from both mating surfaces without scoring the aluminum before the new gasket is seated and the pump is reinstalled in proper sequence. Reassemble in reverse order, refill with fresh oil, and verify oil pressure before returning the Bmw 750I to service.

Frequently asked questions

How much does it cost to replace engine oil pump gaskets on a Bmw 750I?
The gasket itself starts at $31.95 at AutoBuffy, making parts cost low. Total repair cost depends on labor — the oil pump is often buried behind the timing cover or deep in the front of the block, so professional labor can add significantly to the bill. DIYers can keep the job to parts cost alone.
Can I drive my Bmw 750I with a leaking oil pump gasket?
You should not drive with a confirmed oil pump gasket leak. Even a small seep can escalate under heat and pressure, dropping oil level quickly. Low oil pressure starves engine bearings and camshafts within minutes of a significant loss. Check the oil level immediately and have the leak repaired before extended driving.
How long does an engine oil pump gasket last on a Bmw 750I?
Oil pump gaskets are not a scheduled maintenance item and can last the life of the engine under normal conditions. Failure is most common after high-mileage use, overheating events that warp sealing surfaces, or improper reinstallation during a previous oil pump or timing cover job. Inspect it any time the pump or front cover is disturbed.
Is an oil pump gasket the same as the oil pump O-ring?
Not always. Some engines use a flat gasket between the pump body and the block, others use a round O-ring, and many use both — a gasket on the pump face and an O-ring on the pickup tube. Always check your specific engine's configuration and use a kit if both sealing points will be exposed during the repair.
Do I need to replace the oil pump itself when I replace the gasket on a Bmw 750I?
Not necessarily. If the pump body, gears, and pressure relief valve are in good condition and oil pressure tested normally before the failure, replacing only the gasket is appropriate. However, if the pump is already removed for another reason — timing chain, front cover, or high mileage — replacing the pump as preventive maintenance is worth considering.
What happens if the oil pump gasket is over-torqued during installation on a Bmw 750I?
Over-torquing crushes or distorts the gasket beyond its designed thickness, which can crack a paper gasket immediately or cause a rubber gasket to extrude past the sealing surface. Either condition leads to a leak shortly after startup. Always follow the torque sequence specified for your engine and use a calibrated torque wrench, not impact tools.
