Mitsubishi 1428A158 — Fuel Injector Washer
Overview
Fuel injector washer Mitsubishi 1428A158 seals the interface between the diesel injector base and the cylinder head recess to prevent combustion gas blow-by. Formed from annealed soft copper, this seal resists extreme combustion temperatures and cyclic pressure spikes within high-pressure Common Rail injection systems. Dimensions feature an inner diameter of 7.5 mm, an outer diameter of 15.0 mm, and a thickness of 2.0 mm. Cross-referenced directly under OEM part number 1428A158, it conforms to exact factory specifications. The malleable copper composition compresses uniformly upon tightening, taking up micro-imperfections on mating surfaces to prevent injector carbon fouling, seat erosion, and cylinder compression loss.
This part fits Mitsubishi diesel models including L200, Pajero Sport, Pajero IV, Outlander, and ASX fitted with 2.5 DI-D and 3.2 DI-D powerplants. Mechanics fit a fresh copper washer whenever removing a diesel injector, servicing the cylinder head, or cleaning injector wells. Single-use copper washers crush during initial torqueing, meaning reused seals fail to maintain a gas-tight seal. Symptoms requiring washer replacement include exhaust odours inside the engine bay, hissing sounds around the rocker cover, black carbon build-up near the injector bore, engine misfires, and reduced engine power under load.
