Information:

Illustration 1 g02004767
(1) Ring for Identification (2) 228-7094 O-Ring Seal (3) 345-3399 Injector Sleeve An oversized injector sleeve will be introduced in order to improve the life cycle of the cylinder heads. The new sleeve has an oversized outside diameter, which does not allow the injector sleeve to fit the standard bore. The oversized sleeve will have an added ring that is located around the middle of the insert for identification. Also, the new sleeve will require a larger bottom O-ring. Refer to Illustration 1.
Illustration 2 g02004793
(4) Identification markThe remanufactured cylinder head has an identification mark that is located on the top of the cylinder head. This mark indicates the cylinders that have the oversized inserts.
