What is an injector sleeve?

The diesel injector sleeve (a.k.a. fuel injector sleeve) seals and protects the injector in the cylinder head, separating the fuel system from the cooling circuit.

What causes injector cups to fail?

heating cycles will cause the Loc-Tite to degrade and lose its’ sealing properties…but they are usually ‘good’ for a couple hundred thousand miles. OVER-heating (run out of coolant & overheat the cyl head) is another way to cause the cup/sealant to fail…as well as just normal metal fatigue.

How do I know if my injector 7.3 is bad?

Check the exhaust smoke from your vehicle. White smoke is normal when starting your vehicle, but white smoke when driving indicates that there is a loose injector. Black smoke emission can also be normal when accelerating the vehicle, but if you notice black smoke at other times, this indicates a bad fuel injector.

Can I rebuild my own diesel injectors?

Your injector is a highly precise device that measures and injects fuel into the combustion chamber in your diesel engine. Because it is such a highly machined component in the engine, it isn’t recommended to take this task on at home. It needs to be done in a well-established, environment-controlled clean room.
