Bought a 2002 Excursion, and just wanted some advice on what the common things to look for on the 7.3 were. Posted on the Excursion thread but doesn't look like it gets much traffic so figured I'd post here as well. Just sold my 99 cummins, and got a steal on this truck I think. Anyway, want to powerwash the engine, has an oil leak, but hard to find, fan blowing it around. I want to wash it but I know on gas fords, they don't like water and won't start wet. Does that hold true on the 7.3? Also, I believe that I have a engine code that said something about low voltage at injector module. Truck runs great, Garrett GTP 38 turbo, 4" exhaust, Edge Juice with attitude, cold air intake, on 315's. Is there any common things to look for or prone oil leak places on it? Knew my cummins inside and out and have some experiance with the 7.3 but not much. Thanks for the help.
