Valve Guide Stem Seal, 9mm

Victor Reinz 9mm Valve Guide Stem Seal, originally fitted to the four inlet valve guides on Alfa Romeo 101 and 105 series engines, as well as the Montreal.

Manufactured to OE quality standards, these valve stem seals provide excellent durability and performance. They are the preferred choice for all standard engine rebuilds here at VeloceSport and are sold individually.

Key Features:

• Model Compatibility: Suitable for 101 series, 105 series, and Montreal engines.
• OE Quality: High quality Victor Reinz seal, ensuring reliable performance and long lasting durability.
• Original Fitment: Designed for the four inlet valve guides, as per factory specifications.
• Exhaust Valve Guide Consideration: Originally, Alfa Romeo designed exhaust valves without valve stem seals, opting for a looser guide clearance to allow lubrication and cooling.
• Modern Rebuild Option: Some modern rebuilds fit valve stem seals on both inlet and exhaust valve guides, though originally, only the inlet side had them.
• Additional Fitment Option: If you wish to install stem seals on the exhaust side, simply use two sets of VS2570 Inlet Valve Guides.
