Information:
This Program must be administered as soon as possible. When reporting the repair, use "PI3330" as the Part Number, "7751" as the Group Number, "56" as the Warranty Claim Description Code and "T" as the SIMS Description Code. Exception: If the repair is done after failure, use "PI3330" as the Part Number, "7751" as the Group Number, "96" as the Warranty Claim Description Code, and "Z" as the SIMS Description Code.

September 30, 2000Problem
The torque of the injector electronic solenoid valves need to be checked. The valve has four Torx bolts that hold the stator to the housing. If these bolts are not properly tightened, fuel can leak into the oil.

THIS REWORK IS RESTRICTED TO ENGINES LISTED IN THE AFFECTED PRODUCT ONLY.
THIS PIP DOES NOT ALLOW FOR THE REMOVAL OF THE INJECTOR. DO NOT REMOVE ANY OF THE STATOR BOLTS. THIS WILL VOID INJECTOR WARRANTY.
PROCEDURE:
1. Remove the valve covers to reveal the injector assembly/ electronic valve.2. Remove electronic valve terminal connector (two retaining nuts) with a " universal socket. Take the terminal connectors off of the posts.3. The four stator retaining bolts you need to check are now accessible. To properly complete the torque check, the following tools are required.a) Click torque wrench, " drive (capable of accurately measuring 2.0 N m)b) 6" extension " drive.c) universal joint, "drived) T10 Torx bit, " drive4. Set the torque wrench value to (2.1 N m). Check all four bolts and tighten (if needed) until they reach the 2.1 specification.:
DO NOT OVER TORQUE THE STATOR RETAINING BOLTS (2.1 N m). THIS COULD CAUSE FURTHER DAMAGE.
5. Reassemble the engine in the reverse order.a) Torque value of the terminal connector nuts - 3.0 N m b) Torque value for the valve cover bolts - 47 9 N m.
