VVT Valve O-ring for BMW Engines
These high-performance O-rings are designed for BMW's Variable Valve Timing (VVT) system, ensuring precise sealing between the VVT valve and engine components. Made from durable, heat-resistant rubber, they prevent oil leaks and maintain optimal hydraulic pressure for smooth VVT operation.
Key Features:
Material: Fluorosilicone or HNBR (Hydrogenated Nitrile Butadiene Rubber) for superior heat/oil resistance.
Temperature Range: -40°C to +200°C (-40°F to +392°F).
Pressure Resistance: Withstands up to 10 MPa (1,450 psi).
Precision Fit: Exact OEM specifications for seamless integration.
Longevity: Resists aging, cracking, and chemical degradation from engine oils.
| Part Number | Engine Series | BMW Models (2010-2023) | Chassis Codes | Production Years |
|---|---|---|---|---|
| 11367506178 | N20, N26 | 320i, 328i, 520i | F30, F10 | 2011-2017 |
| B48 | 330i, 530e, X1 xDrive | G20, G30, F48 | 2017-Present | |
| 11367546379 | N55 | 335i, 535i, X5 xDrive35i | F10, F15 | 2010-2016 |
| B58 | 340i, 540i, X3 M40i | G30, G01 | 2016-Present |
Note: Always verify compatibility using your VIN. Some models may require additional gaskets.
Purpose: Seals the VVT valve assembly to prevent oil leaks, ensuring stable hydraulic pressure for camshaft timing adjustments.
Principle: The O-ring creates an airtight barrier between the VVT solenoid and engine block, allowing precise oil flow control to advance/retract camshaft timing.
Failure Impact: A worn O-ring causes oil leaks, leading to erratic valve timing, poor performance, or check engine lights (e.g., BMW fault code 2A82).
Tools Required: Torx screwdriver, pick tool.
Steps:
Remove the VVT solenoid.
Replace the old O-ring (avoid twisting).
Lubricate with clean engine oil before reassembly.
