BMW Valve Cover Gasket Set - Elring 11127588418

Product Information

Valve cover gasket leaks are a well-known issue on higher mileage BMWs. Over time, the rubber gasket shrinks and hardens from exposure to engine heat and oil, eventually causing it to lose its seal. Replacing it with a quality OEM gasket ensures a proper seal and helps maintain long-term engine cleanliness and performance. Always choose quality parts to avoid future leaks and repairs.

Engine Valve Cover Gasket Set
This gasket seals the valve cover to the cylinder head, preventing oil and vapors from escaping. It must compress slightly to conform to imperfections in the mating surfaces. Most modern gaskets are rubber-based, though some include reinforcement for added durability. Older vehicles may use cork, which requires careful installation.

Failure Symptoms:

• Age: Gaskets become brittle and shrink, leading to oil leaks at the valve cover joint.
• Physical damage: Excessive tightening during installation can crush and deform the gasket.
• Chemical damage: Some sealants and chemicals can degrade the gasket material.
• Obvious oil leaks: Oil may visibly leak down the engine from the valve cover area.
• Mysterious oil leaks: Oil residue in unexpected places due to airflow or splash patterns.
• Air intake faults: Bad leaks can affect airflow, leading to rough idling or engine warning lights.
• Burning oil smell: Oil leaking onto the hot exhaust system may burn off, creating a strong odor while driving.
