To reduce the possibility of injector sleeve damage, do not use anything metal to scrape the copper injector sleeves.

Use a clean wooden stick with a clean cloth wrapped around the end to remove all the carbon from the copper injector sleeves in the cylinder head.

Use chip removing unit, Part Number 3823461 or ST-1272-11, to remove the carbon from the top of the piston.

 CAUTION 

Do not drive the injector in by striking the solenoid valve area. This can damage the solenoid or cause the injector to be out of alignment in the bore, which will result in o-ring damage.

Place the injector in the cylinder head injector bore with the injector solenoid valve toward the intake port. Align the injector equally between the valve springs.

Use injector tool, Part Number 3823579, to seat the injector in the bore.
