B-M-W N46 Engine Oil pump 318 320 E46 E90 E42 X1 Z4 N42 Original used auto parts

Technical Parameters

• Design:

  • Gear-driven pump with aluminum housing and hardened steel gears.

  • Includes pressure relief valve to regulate oil flow.

• Flow Rate:

  • ~25–30 liters/minute at 6,000 RPM (varies with engine condition).

• Oil Pressure:

  • 3–5 bar at operating temperature (idle: ~1.5–2 bar).

Selling Points

1. OEM Authenticity:

   • Genuine BMW part, designed for the N46 engine (used in models like E46 3 Series, E90 3 Series, and 1 Series). Ensures precise fitment and reliable performance.

2. Critical Functionality:

   • Maintains proper oil pressure (3–5 bar at operating RPM) to prevent engine damage, crucial for the N46’s longevity given its history of timing chain and oil system issues.

3. Cost Savings:

   • Significantly cheaper than a new OEM pump while retaining BMW’s engineering standards (ideal for budget-conscious repairs/rebuilds).

4. Condition:

   • Minimal wear (e.g., intact gears, no scoring on housing, functional pressure relief valve). Tested for smooth operation and absence of leaks.

5. Rarity:

   • Original N46 oil pumps are increasingly scarce in good condition, raising value for restorations or OEM-focused repairs.

6. Compatibility:

   • Fits N46 engines in 316i, 318i, 320i, and 320si models (confirm part number for exact application).
