FAQ

Q1: Is this valve oil seal a direct fit for my Mitsubishi S6K engine?
A1: Yes, this seal is designed to OEM specifications for the S6K engine. We recommend verifying your existing part number against 5i-7564 or 30604-22801 before ordering. If your engine has been modified or rebuilt with non-standard components, please consult your service manual for confirmation.

Q2: How do I install this valve oil seal properly?
A2: Installation should be performed by a qualified diesel mechanic. The valve seal is typically pressed onto the valve guide using a specialized installation tool to avoid damaging the rubber lip. Ensure the valve stem and guide are clean and lubricated before installation. Always replace seals on all valves during a cylinder head service to maintain balanced performance.

Q3: What maintenance schedule is recommended for these seals?
A3: Valve oil seals are generally replaced during major engine overhauls or when symptoms of oil leakage (such as blue smoke at startup) appear. For standard S6K engines in heavy-duty use, inspection every 2,000-3,000 operating hours is recommended. Regular checks of crankcase ventilation and oil pressure can also help extend seal life.
