Some 3100 engines have been experiencing leaks from the oil filter base. The improper torque on the center bolts of the oil filter base is causing the leak.

Perform the torque sequence to the oil filter base. Repeat the torque sequence to the oil filter base in order to prevent a leak. The torque sequence can be found in the following publications:

• Disassembly and Assembly, RENR7482, "Engine Oil Filter Base - Install"

• Disassembly and Assembly, SENR5120, "Engine Oil Filter Base - Install"

• Special Instruction, REHS2380, "Torque Procedure for the 0R-8839 Oil Cooler Core As "

The additional torque sequence will provide a more consistent torque in order to help prevent the external oil leaks.
