1. Quick Notice
Confirm your engine code (8DC11) and original gasket part number before ordering. Three reference numbers — ME084081, ME064981, and ME092855 — are cross-compatible for this engine. Professional installation required. Always use a new gasket when removing the cylinder head.
2. Description
The 8DC11 cylinder head gasket seals the interface between cylinder head and engine block on the Mitsubishi Fuso 17.7L V8 diesel engine. This engine is found in Super Great heavy-duty trucks, producing approximately 355 horsepowe. The gasket withstands extreme combustion pressure, high-temperature cycling, and continuous vibration. Constructed from premium material for superior durability. Common failure symptoms include external coolant seepage at the head joint, oil contamination, persistent engine overheating, white exhaust smoke, and pressure loss from combustion gas leakage between cylinders-8. Replacement restores compression sealing, maintains operating temperature, and prevents cross-contamination of fluids. These three part numbers — ME084081, ME064981, and ME092855 — are cross-referenced and fully interchangeable for this application-8-17.

Gasket Orientation: Install with the part number facing upward and toward the intake side. Left (LH) and right (RH) gaskets must be placed on their respective cylinder banks. Note the identification marks before removing the old gasket.
Surface Preparation: Both cylinder head and block surfaces must be clean and flat. Remove all old gasket residue using a plastic or wooden scraper. Do not use abrasive discs on sealing surfaces. Check cylinder head flatness against manufacturer specifications.
Head Bolt Torque: Tighten cylinder head bolts progressively. First stage: 37 ft-lbs (50 Nm). Second stage: additional 120-degree angle turn in the specified sequenc. Replace head bolts if previous stretch marks exceed two punch marks.
Engine Oil Protection: One of the few visible signs of a blown head gasket is engine power loss due to pressure escaping past the seal. Oil and coolant passageways may also begin leaking into areas where they should not be, requiring immediate gasket replacement-8.
5. FAQ (One by One Question and Answer)
Q1: Are ME084081, ME064981, and ME092855 different gaskets?
A1: No. These three part numbers reference the same cylinder head gasket and are fully interchangeable. Any of these numbers can be used for the 8DC11 engine-8.Q2: Which Mitsubishi Fuso trucks use the 8DC11 engine?
A2: The 8DC11 V8 diesel engine (17.7L, approx. 355 HP) is found in Fuso Super Great heavy-duty trucks, including model codes U-FV419JD, FV519JXD, and various dump truck configuration.Q3: How do I know if my head gasket has failed?
A3: Common signs include engine power loss, white exhaust smoke, coolant in engine oil (milky appearance), persistent overheating, and exhaust bubbles in the radiator overflow tank.Q4: Does this gasket require special sealant during installation?
A4: Install the gasket dry on clean surfaces. Apply liquid gasket only to specified areas as indicated in the service manual — typically at the mating surface where the timing cover meets the cylinder block. Do not apply sealant directly to the head gasket sealing surface.Q5: How many gaskets are needed for one 8DC11 engine?
A5: Two head gaskets are required — one for the left cylinder bank and one for the right cylinder bank. Verify whether your listing includes both sides or a single gasket.
