BMW Valve Cover Gasket - Reinz 11121730272

Product Information

This Victor Reinz valve cover gasket seals the valve cover to the cylinder head and addresses one of the most common sources of oil leaks in older BMW engines. As the original gasket ages, it can shrink and harden, leading to oil seepage and burning smells. Replacing it with this high-quality aftermarket gasket helps restore a proper seal and prevent future leaks.

Engine Valve Cover Gasket
Designed to seal the upper portion of the cylinder head, this gasket must compress slightly to seal surface imperfections. Most modern gaskets are made from durable rubber compounds, while vintage applications may use cork, requiring precise torque during installation to avoid crushing.

Failure Symptoms:

• Age: Hardening over time leads to brittle gaskets and oil leaks.
• Physical damage: Over-tightening bolts can crush or distort the gasket surface.
• Chemical damage: Incompatible sealants can break down gasket materials.
• Obvious oil leaks: Visible oil along the cylinder head or valve cover area.
• Mysterious leaks: Oil residue may accumulate in unexpected places due to engine airflow.
• Air intake faults: Significant leaks can affect engine vacuum and cause running issues.
• Burning oil smell: Leaked oil on the exhaust manifold burns off while driving, producing a strong odor.
