Was warming up the 04 F-250 to head out snowmobiling today and within minutes there was about 3-4 quarts of oil lying on the ground. From what i can see it looks like its coming from the rear of the motor, sowewhere? I just had the shop replace the hpop, they said it was starting to leak. Can anyone tell me where this hpop is located? Makes me wonder if they even changed it as they said that if the o ring went out the truck would just spew all the oil out of the motor, kind of like what it seems to be doing...
