FAQ

Q: How do I know if these are the intake or exhaust valve seats?
A: In the Mitsubishi K4D engine, ME190289 is typically the intake valve seat, and ME190267 is the exhaust valve seat. Please consult your engine service manual or compare the dimensions (outer diameter, inner diameter, and height) with your old valve seats to confirm correct placement.

Q: Do I need to machine these valve seats after installation?
A: Yes. While these seats are manufactured to OEM standard dimensions, professional installation typically requires cutting and lapping the new valve seats to achieve a perfect seal with your specific valves. We recommend having a qualified machine shop perform this work to ensure proper valve recession and sealing.

Q: Can these valve seats be used on other Mitsubishi engine models?
A: These seats are specifically designed for the K4D engine. They are not compatible with other models like the 4D31, 4D34, or 6D14 unless the seat dimensions are identical. Always cross-reference the part numbers (ME190289 & ME190267) against your engine’s parts catalog to confirm fitment.
