Introduction
The permanent solution for the problem that is identified below is not known. Until the permanent solution is known, use the solution that is identified below.Problem
The above listed serial numbers have had issues with metal shavings in the Hydraulic Electronic Unit Injector (HEUI) oil passages. These shavings were left in the HEUI oil passages as a result of a nozzle that was not operating correctly.Solution
Return 0R-8849 Cylinder Head Gp with date codes 09006 through date code 12006. Return the 0R-7907 Cylinder Block Gp with the following sequence numbers.
