7. Important Compatibility Notes
L3E piston rings are fully interchangeable with L2E and L3A piston rings due to the same 76mm bore and ring specification. However, pistons, cylinder liners, cylinder head gaskets, bearings and valve parts are not universal among L2E, L3A and L3E engines because of different internal engine structures and design parameters.
Please strictly verify the original engine model before ordering. Incorrect part installation will cause poor compression, serious oil consumption, engine jitter and even permanent mechanical damage.
8. Warranty Policy
All Mitsubishi L3E engine overhaul kits support 12-month quality warranty under professional installation and normal operating conditions. The warranty is invalid for damage caused by improper assembly, overload operation, oil shortage, water shortage and artificial damage.
