Figure 228 — Cleaning Injector Tip Bore
The injector bore sealing tool must be used to
prevent debris from entering the fuel passage.
When replacing the copper sleeves, it is
important to check that the sleeve bore in the
cylinder head is free from any carbon deposits or
other residue (i.e., pieces of O-ring, etc.) before
installing a new copper sleeve. Reclean if
necessary.
18. Using the chip vacuum, remove all debris
from the copper sleeve bore.
Do not attempt to blow away debris using
compressed air. Doing so can result in eye injury.
19. Remove the injector bore sealing tool from
the cylinder head. Using the chip vacuum,
remove any remaining debris.
INSTALLATION PROCEDURE
1. Before installing the copper sleeve, inspect it
to ensure that it is the correct part. The
correct sleeve is identified by two concentric
circular grooves machined into the top
surface.

2. Lubricate a new copper sleeve O-ring with
coolant. Install the O-ring on the copper
sleeve and lubricate again with coolant.
Always use a new O-ring.
3. Place the new copper sleeve on the
installation tool.
Do not place the injector nozzle gasket (flat
washer) in the copper sleeve, as this will damage
the swaging bit.
