FAQ

Q: How do I know if this valve guide (ME031886/ME031888) will fit my engine?
A: This valve guide is specifically designed for the Mitsubishi 6D15 diesel engine. To confirm fitment, please check the part number on your old valve guide. If it matches ME031886 or ME031888, or if you are rebuilding a 6D15 engine, this is the correct part. We recommend cross-referencing your engine serial number with the 6D15 model.

Q: What is the recommended installation procedure for a new valve guide?
A: Installation is typically performed by a qualified mechanic during cylinder head service. The old guide is pressed out using a hydraulic press and a suitable drift. The new valve guide should be pressed in from the top of the cylinder head (camshaft side) to the correct height. After installation, the valve guide bore may require reaming to achieve the proper valve stem-to-guide clearance as specified by the Mitsubishi service manual. Lubricate the guide with clean engine oil before inserting the valve.

Q: What are the signs of a worn valve guide that needs replacement?
A: Common symptoms include excessive oil consumption, blue smoke from the exhaust on startup or deceleration, and a ticking noise from the valve train. Worn guides can also cause poor engine performance and rough idling due to improper valve sealing. These symptoms often appear together, indicating a need for cylinder head service, including valve guide replacement.
