Detailed Description

Mahle VS50123 is an engine valve cover gasket engineered for vehicles that require a molded rubber sealing profile. Mahle is known for gasket and sealing products used by OEMs and technicians worldwide, and this part follows that approach with an OEM-standard construction focused on proper fit and leak control. This part cross-references FEL-PRO (e.g., VS 50320 R) and Rol (e.g., VS999) for the same application. It is a strong match for long-tail searches such as valve cover gasket for 2000-2005 Chevrolet Impala, 1997-2008 Pontiac Grand Prix valve cover gasket, and 1988-2005 Buick LeSabre valve cover gasket replacement. The part number VS50123 is also useful when verifying the correct seal for Buick, Chevrolet, Pontiac, and Oldsmobile applications.

What It Helps Fix

• Oil seepage around the valve cover sealing surface
• Oil residue on the engine exterior near the cylinder head
• Burning oil smell caused by a leaking valve cover seal
• Loss of sealing integrity from a hardened or flattened gasket
• Maintenance issues during valve cover service on GM engines
