FAQ

Q1: Will this cylinder head fit my Mitsubishi 4M40 engine without modifications?
A: Yes, this is a direct OEM replacement. It matches the original casting and machining specifications, so no modifications are required. Ensure you use a new head gasket and torque the bolts to the manufacturer’s specifications (typically 90-100 Nm in sequence).

Q2: What is the recommended maintenance interval after installing this cylinder head?
A: After installation, we recommend checking the valve clearance after the first 500 km (300 miles) of operation. Thereafter, follow the standard engine maintenance schedule, typically inspecting the head bolts and gasket every 50,000 km (30,000 miles) for heavy-duty applications.

Q3: How can I verify the quality of this cylinder head before installation?
A: Before installation, inspect the deck surface for any scratches or warping using a straight edge. Check that all valve guides and seats are clean and free from debris. If in doubt, have a machine shop verify the flatness (should be within 0.05mm over 200mm). All our heads are pressure tested and certified before shipping.
