This fuel injector sleeve kit provides the necessary seals and components to properly seat and seal the fuel injector within the cylinder head, ensuring efficient fuel delivery and preventing combustion leaks. Manufactured from durable materials resistant to fuel and heat, this kit offers a reliable seal that prevents blow-by and maintains optimal injection pressure. Operators may notice rough idling, reduced engine power, increased fuel consumption, or difficulty starting if the injector sleeves are leaking or damaged.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Initial symptoms of failing fuel injector sleeves often include a noticeable increase in engine vibration or rough idling, especially at low RPMs. This can progress to a significant loss of engine power, increased black smoke from the exhaust, and higher than normal fuel consumption. If left unaddressed, persistent leaks can lead to cylinder wash-down, oil dilution, and potential internal engine damage.
Ensure the cylinder head bore for the injector sleeve is perfectly clean and free of any carbon deposits or old sealant before installing the new sleeve. Use the correct installation tool to seat the sleeve fully and squarely without cocking it.
Inspect the fuel injectors themselves for wear or damage, and check the fuel system for proper pressure when replacing injector sleeves.
