FAQ

Q1: How do I confirm this valve seat is the correct part for my specific Mitsubishi engine?
A1: The most reliable method is to cross-reference the part number stamped on your original valve seat or listed in your engine’s official service manual with our OEM numbers (ME029096 or ME029005). Also, verify your engine model (4D30 or 6D31).

Q2: What is the recommended installation procedure for this valve seat?
A2: Valve seat installation is a precision engine rebuilding task. It typically requires heating the cylinder head (thermal fitting) or using a press for interference fit, followed by machining (cutting and grinding) to achieve the correct valve seat width and contact angle. We recommend installation by a qualified mechanic with proper tools.

Q3: Do you provide technical support or compatibility documentation with the order?
A3> Yes. Along with the physical product, we can provide the machinery test report for the batch. For specific compatibility questions prior to ordering, please contact our technical sales team with your engine’s full model and serial number for verification.
