Apex Gaskets AVS8023 Engine Valve Stem Oil Seal Set

The Apex Gaskets AVS8023 is an engine valve stem oil seal set designed to restore proper oil control at the valve stems in the cylinder head. Valve stem seals prevent engine oil from being drawn down the valve stems and into the combustion chamber — a common cause of blue exhaust smoke, elevated oil consumption, and fouled spark plugs.

Key Features:

• Engineered to meet or exceed OEM specifications for a precise, leak-free fit
• Manufactured from high-quality, heat-resistant elastomer compounds to withstand extreme engine temperatures and pressures
• Covers both intake and exhaust valve stem seals for a complete repair
• Consistent dimensional accuracy ensures proper sealing lip tension on valve stems
• Compatible with domestic, Japanese, Korean, and popular European engine applications

Apex Gaskets products are manufactured using advanced materials and production technologies, providing dependable performance and durability. The AVS8023 valve stem seal set is an ideal solution for engine rebuilds, cylinder head restorations, or any repair where valve stem oil sealing has been compromised.
