Note: Always verify fitment using your VIN (Vehicle Identification Number) before purchase.

Compatible BMW Models (Selected Examples):

Product Overview

Part Number: 11667566483
Compatibility: Designed for BMW engines (specific models may vary; verify fitment).
Function: Seals the vacuum pump to prevent oil leaks and maintain engine vacuum pressure.

Key Attributes

1. Precision Fit – Engineered to match OEM specifications for BMW vacuum pumps.

2. Durability – Resists wear, heat, and chemical exposure from engine oil.

3. Sealing Performance – Ensures no air/oil leakage between the pump and engine block.

Material

• High-Quality Rubber or Viton® (Fluoroelastomer):

  • Resistant to high temperatures (up to 200°C/392°F).

  • Immune to degradation from engine oils, fuels, and coolants.

  • Flexible yet durable for long-term compression.

Working Principle

The gasket sits between the vacuum pump and the engine block, creating an airtight seal. This:

1. Maintains vacuum pressure for brake boosters/emission systems.

2. Prevents oil from leaking into the vacuum system.

3. Reduces friction and vibration between metal components.

Advantages

✔ OEM Equivalent – Meets BMW’s original standards.
✔ Leak Prevention – Critical for engine efficiency and emissions compliance.
✔ Easy Installation – Replaces worn-out gaskets during maintenance.
✔ Cost-Effective – Avoids expensive pump repairs due to seal failure.

A: Confirm compatibility with your model (e.g., F30 3 Series, E90, or others). Cross-check part numbers in your repair manual.

Q2: Symptoms of a failing vacuum pump gasket?
A: Oil leaks near the pump, reduced braking power (if vacuum-dependent), or engine warning lights.

Q3: How often should it be replaced?
A: Typically during vacuum pump servicing or if leaks are detected (no fixed interval).

Q4: Can I reuse the old gasket?
A: No – Always replace it to ensure a proper seal.

Q5: DIY installation tips?
A: Clean mating surfaces thoroughly, apply no sealant (unless specified), and torque bolts evenly.
