FAQ

Q1: Is this cylinder head compatible with all Mitsubishi K3D engine variants?
A: Yes, the MM408814 cylinder head is designed as a universal replacement for the K3D engine block. However, we recommend checking the valve seat size (standard: 30mm intake, 28mm exhaust) and head bolt pattern (M10x1.25) against your existing unit. Contact our technical support with your engine serial number for confirmation.

Q2: What maintenance steps should be taken before installing a new cylinder head?
A: Before installation, ensure the engine block deck is clean and free of debris. Replace head gasket, bolts (use new torque-to-yield bolts), and check valve clearance (0.25mm intake, 0.30mm exhaust cold). Torque head bolts in sequence to 80 Nm (first pass), then 120 Nm (final pass). Allow the engine to run for 20 minutes, then retorque after cooling.

Q3: How do I verify the part number if my current head has no markings?
A: Measure the cylinder head length (approx. 380mm for K3D), count the number of valve guides (8 total for 4-cylinder), and check the water port layout. Cross-reference with your engine block casting number (e.g., K3D-XXXXX). Alternatively, send us photos of the head (top, bottom, and side views) and engine plate, and we will identify the correct part within 24 hours.
