i noticed an oil leak on my truck, seems its coming from the high pressure oil pump located on top front of engine (03 7.3 power stroke turbo). is this a pretty straight forward repair. doesn't look to tough to do, remove pump and replace gasket. just wanted to make sure that when i remove pump something aint gonna drop inside engine or something. i am gonna buy a manual before i tear into it, but was kinda hoping someone here has already done this and could gimme their feedback on this. thanks..
