I have an f350 7.3 diese. We pulled into bass pro shop in Springfield, MO are oil was leaking we went into and store snd came out and a signifcant amount oil was under the truck and none showed up on the dip stick. Need a diseal mechanic in Springfield Missouri.
The mechanic we found said there was a crack in the pedestal of turbo were the high pressure hose attaches. The part is in order and will be here a couple of days. So are exploring Springfield, MO for a few days. Good Sam road service did a great job helping us. I could not be more satisfied with there service.
HPOP seal, oil filter loose or has failed, also the copper o-ring on the drain plug can fail, mine developed a pretty good leak, not as fast as yours but a pretty good spot on the garage floor. I checked the drain plug and it was tight, went to change the oil and the copper 0-ring was still there but would not seal, changed it and all good.
