I was accelerating and heard a pop and lost power. I limped my 06 F350 home and accelerated three blocks away from home. I stall when I took my foot off the pedal. I have just replaced my injectors, installed an EGR delete, and taken it in to the Ford dealer who thinks it is a high pressure oil leak. I have hooked up a air line to the icp sensor and supplied 12V to the ipr sensor on the hpop. All I hear is alot of air moving below the hpop. Should I go into the motor more and check the branch tube? I have also replaced the ipr valve, and when I pressurize the passenger side oil rail I hear a leak with the ipr valve open and no leak with it closed but during both of these situtations there is a large leak in the lower part of the engine is this normal?
