FAQ

Q: Is this kit a direct replacement for my Mitsubishi S4L engine?
A: Yes, this kit is designed to be a direct replacement for the standard Mitsubishi S4L and S4L2 engines. However, we strongly recommend checking your engine’s specific serial number and the original gasket part number (31A94-00081 or 31A01-33300) to confirm compatibility, as minor design changes may exist in different production years.

Q: Does this kit include the head gasket and valve stem seals?
A: Yes, as a “full gasket kit,” it typically includes all major gaskets (cylinder head, intake/exhaust manifold, oil pan, valve cover, etc.) and the necessary seals, including valve stem seals. Please refer to the package contents list for the exact component count.

Q: What is the recommended procedure for installing this gasket kit?
A: We recommend following the official Mitsubishi service manual for your S4L/S4L2 engine. Proper torque specs, tightening sequences, and surface preparation (cleaning the block and head) are critical for a successful seal. Ensure all surfaces are clean and free of old gasket material before installation.
