ACDelco 90215296 Engine Valve Stem Oil Seal

The ACDelco 90215296 is a GM Genuine Parts Engine Valve Stem Oil Seal engineered to OE specifications for General Motors vehicles. This positive-type slip-fit valve stem seal is designed to control oil consumption and reduce exhaust emissions by precisely regulating the film of oil that lubricates the valve stem as it moves through the guide.

Key Features:

• OE-Quality Construction: Steel and rubber composite design engineered to match original equipment standards set by General Motors
• Positive Seal Design: Slip-fit (SLP-1) positive seal style maintains consistent sealing force around the valve stem for reliable oil control
• Precise Fitment: 8 mm (0.314 in) inside diameter, 16 mm (0.629 in) outside diameter, and 10 mm (0.393 in) thickness for accurate, leak-free installation
• GM Backed: Designed, engineered, and tested to rigorous GM standards — the same seal installed at the factory or validated for GM vehicles
• Includes: One engine valve stem oil seal

As a GM Genuine Parts component, the ACDelco 90215296 valve stem seal helps prevent oil from being drawn past the valve stem into the combustion chamber, protecting against oil burning, fouled spark plugs, and excessive emissions. It is a direct OE replacement for compatible General Motors engines.
