Key Advantages

1. Precise inner diameter closely fits valve stems, effectively blocks engine oil from flowing into the combustion chamber and causing oil burning.
2. Premium fluororubber material withstands continuous high operating temperature, resistant to aging, hardening and cracking.
3. Built-in stainless steel spring maintains stable pressing force to guarantee long-term sealing reliability.
4. Ideal replacement parts for cylinder head overhaul, valve service and fixing blue exhaust smoke and excessive oil consumption problems.

Product Description

Valve stem oil seals are mounted on intake and exhaust valve guides to control engine oil consumption. When seals lose elasticity due to long-term wear and heat aging, lubricating oil will leak into cylinders and burn, resulting in blue smoke during startup or acceleration, continuous oil level drop and excessive carbon buildup inside the engine.

This 8-piece set fully matches the 8 valves of Mitsubishi 4D35 diesel engine. Professional technicians are required for installation to avoid scratching valve stems and damaging the seal lip.

Shipping: Sea freight, air freight and international express are all available.

A: Blue smoke from exhaust pipe on cold start or hard acceleration, frequent engine oil reduction without external leakage, heavy carbon deposits on pistons and combustion chamber.

Q2: Professional installation notes

A: Use dedicated valve spring compressor tool for disassembly and assembly; apply a small amount of clean engine oil on the inner sealing lip; prevent sharp edges from cutting the rubber surface.

Q3: Engine compatibility range

A: Only compatible with Mitsubishi 4D35 diesel engine, not suitable for 4D30, 4D32, 4D34 and other Mitsubishi diesel engines, please confirm engine model before purchase.
