These injector sleeve composite sealing bushings are installed between the fuel injector sleeve and the cylinder head bore of the CAT 3408 V8 diesel engine. Their core function is to seal the gap to avoid diesel fuel leaking into the cooling water channel, prevent coolant from entering the combustion chamber, and also block high-pressure gas blow-by from the cylinder, eliminating engine abnormal water loss, white exhaust smoke and fuel dilution of engine oil.

They are mandatory replacement consumables during cylinder head disassembly, injector maintenance and engine top overhaul for CAT 3408 series power units.

1. Why need to replace these injector sleeve seals?
   
   Aged rubber will harden and crack, causing fuel mixing with coolant, engine overheating, white smoke emission and shortened injector service life.
2. How many pieces are needed for one CAT 3408 engine?
   
   Total 24 cylinders require 24 sealing bushings, exactly the full quantity shown in this package.
3. What other parts to replace together?
   
   Recommend replacing cylinder head gasket, valve oil seals, injector O-rings and full upper gasket set synchronously for complete overhaul.
