FAQ

Q1: Is this injector nozzle sleeve a direct fit for my Mitsubishi 6D40 engine?
Yes, this sleeve is designed as a direct replacement for the OEM part number 8-98023-526-0. It matches the exact dimensions and material specifications required for the 6D40 cylinder head. We recommend verifying your existing part number to ensure a perfect match.

Q2: What is the proper installation procedure for this part?
Installation requires specialized tools to avoid damaging the sleeve. The cylinder head bore must be clean and free of debris. Apply a thin layer of thread locker or sealant (if recommended by the engine manual) to the outer diameter of the sleeve before pressing it in. Use a proper driver to seat the sleeve to the correct depth. Consult your engine’s service manual for torque specifications and specific instructions.

Q3: What are the common signs of a failing injector nozzle sleeve?
Symptoms include external fuel leaks around the injector, white smoke from the exhaust (indicating unburnt fuel), rough engine idle, loss of power, and fuel dilution of the engine oil. A compression test or a leak-down test can help diagnose a bad sleeve.
