FAQ

Q1: How do I confirm this seal will fit my specific Mitsubishi S6K engine?
A1: The surest method is to cross-reference the part number currently on your engine. This seal replaces OEM numbers 5i-7564 and 30604-22801. If possible, match the old seal’s physical dimensions and shape with our product specifications or consult your engine’s service manual.

Q2: What are the consequences of a failing valve oil seal in a diesel engine?
A2: A worn valve seal allows engine oil to leak down the valve stem into the combustion chamber. This leads to increased oil consumption, blue-tinted exhaust smoke (especially on startup), fouled spark plugs (in gasoline engines), and potential carbon buildup on valves and pistons, reducing engine efficiency and power.

Q3: Do you offer technical support for installation?
A3> While we supply the component, installation should be performed by a qualified mechanic familiar with diesel engine overhead service. The process typically requires removing the cylinder head or valve cover, compressing valve springs, and using specialized tools. Always refer to the official Mitsubishi S6K engine service manual for the correct torque specifications and procedural details.
