Mark the valves to identify their location.
Compress the valve springs using the valve spring compressor service tool, Part Number 3164329.
Position the replacer screw (4) above the injector bore and install the two capscrews (5) in the cylinder head where
the hold-down clamp screws were removed.
Tighten the capscrews (5).
Torque Value: 5 Nโขm [ 44 in-lb]
NOTE: The valves are not evenly spaced from the injector bore. It is important to align the slots in the valve spring
compressor plate with the valve springs.
Apply anti-seize compound to the replacer screw (4) threads. Always read and follow label precautions.
Position the valve spring compressor plate (1) on the replacer screw (4) and align the slots in the valve spring
compressor plate with the valve springs.
Install the washer (3) and nut (2) on the replacer screw (4).
Turn the nut (2) clockwise to compress the valve springs.
Continue turning the nut (2) clockwise until the valve collets can be removed using a magnetic tool, such as the
end of a magnetic screwdriver.
Remove the valve collets and the valve spring compressor service tool.
Remove the valve spring retainer and valve springs.
NOTE: Keep the valves in a labeled rack with the associated valve collets, spring retainers and springs.
This will aid in the assembly of the components as a matched set.
Remove the valves.
NOTE: Prior to removal of the valve stem seals, note the color of the valve stem seal installed at each valve
location. The same color valve stem seal must be installed in the same valve location when the cylinder head is
assembled.
Colors Used:
โข Green (exhaust valves)
โข Yellow (intake and exhaust valves)
Use boot pliers, Part Number 3163293, to remove the valve stem seals.
NOTE: Prior to the removal of the valve seat inserts, see the Initial Check and Clean and Inspect for Reuse sections
of this procedure. The condition of the valve, the amount of recess, and the sealing of the valve on the seat insert all help determine whether or not a seat insert needs to be replaced.
โข If required, remove the valve seat inserts.
โข Inspect the valve-insert-to-cylinder-head contact area.
A sufficient groove for the remover must exist.
โข If there is sufficient valve insert groove area, proceed to the next step.
โข If the valve insert groove area is not sufficient, use the valve seat insert cutting kit, Part Number 3376405, to
create a sufficient groove.
Use the slide hammer remover, Part Number 3376617, with valve insert remover, Part Number 3165170, to
remove the valve seats.
NOTE: Make certain the valve insert remover assembly is perpendicular to the cylinder head when installed.
Insert the valve insert remover assembly into the valve insert and rotate the T-handle clockwise until the remover
loosely grips the valve insert.
Position the valve insert remover assembly into the valve insert groove area. Tighten the T-handle firmly, allowing
the remover to expand under the valve insert or into the cut groove.
Strike the slide hammer remover against the top nut until the valve insert is removed. Turn the T-handle
counterclockwise to release the valve insert from the remover.
