The truck is a 2003 6.0 with 130,000 miles and serviced regularly. There are no other known problems with the truck. It starts just fine in mornings even when below freezing. Not once have I experienced a rough start/lug. I am about to put some RevX in to help protect the injectors a little more. I just did FCDP EGR delete a few months back.
The PROBLEM: I took a 60 minute drive to the near by sand dunes and pulled an open bed trailer. When I returned home to unload the bikes, I shut the truck off... and 15 minutes later when getting ready to leave-the truck would crank but wanted no business turning over. After about 30 more minutes of me $hittin bricks it finally turned over after a long hard crank. Once it turned, the truck ran like a champ. No lugging, no rough idling, no white/black smoke. It ran like she was built to.
Buddies in town have said it could be o-rings, IPR valve, or the High/Low pressure oil pumps. Many have leaned towards the IPR since it is a 2003. Does this sound right? What do you guys think my odds are as to what my problem is.
