1. Standard inner diameter fits valve stems tightly, effectively blocks engine oil from entering combustion chambers.
2. High temperature fluororubber withstands harsh diesel engine exhaust heat, not prone to aging, hardening and cracking.
3. Integrated stainless steel spring maintains constant clamping force for long-term stable sealing performance.
4. Core replacement parts for cylinder head overhaul, valve train maintenance and eliminating blue smoke oil burning issues.

Valve stem oil seals are installed on intake and exhaust valve guides to control oil consumption. When seals degrade and lose elasticity, lubricating oil will seep into cylinders and burn, causing blue exhaust smoke, excessive oil consumption and heavy carbon buildup on pistons.

This full set contains 16 pieces matching the full 16 valves of 4D56U engine. Professional dismantling and installation by experienced technicians is required to avoid scratching valve stems and seal lips.
