Problems ****Transfer Pump Valves**** The fuel transfer pump on the above engines has three 1W6182 Valve Assemblies. The one valve in the piston can break in extremely cold weather due to excessive restriction from jelled fuel. Some damage can also occur to the other valve assemblies. A new valve with less flow restriction is now used in the piston and at the other two locations in the pump. These valves are directly adaptable to earlier engines. ****Combustion Gas Leakage Around Fuel Nozzles**** There is a possibility that combustion gases can escape by a fuel injection nozzle and into the adapter. The high temperatures soften the end of the nozzle body and cause the tip to come off. The usual cause for escaping combustion gases is either a loose nozzle in the adapter or a cut in the carbon dam (gas seal). See Illustration 1. Nozzle hold down clamps are all now tightened properly, and an improved chamfer is machined inside the bottom of the adapters to prevent cutting the carbon dam.
