Fuel in oil, Injectors or cp3?
Well, did the major build, new Dragonfly +50hp injectors, Banks billet torque coverter, full Transgo shift kit, and Airdog II DF-165. All was great, idle a bit rougher than before, but lots of power. After a couple days noticed high reading on dipstick, drained, had 4 quarts extra. Hooked up a guage onto Airdog, was at 10.5lbs, dialed it down to 5.5lbs, put in new oil, went for a few hour burn, drained oil, 2 quarts extra. Does anyone know if fuel can be pushed past the seal in the cp3 pump? If so, at what pressure? And if the seal goes back into place after the extra pressure is gone? I expect that a bad injector is the problem, just would like to rule out the fuel pressure to the cp3 before I send them to get tested. Thanks for your replies on this brain scratcher, Wade.
