Ok I just bought a 2001 F-250 CC XLT 4X4 with a 7.3 Powerstroke, no mods as far as I know. Here is the problem, the truck has had a cold start issue since purchase, ambient temp has been 85 deg. average, after several attempts it will start and run fine till i let the truck sit for 6 hrs or so. I found that my IPR valve has come apart, I figured this was the issue, while headed to the parts store the truck started smoking, and loosing power, I shut the truck down, pulled over to inspect, and found the high pressure oil line to the left head had ruptured, leaking oil all over. I proceeded to check the oil to find none on the stick! No sickening grinding or tell tale knock of the bearings giving up, and motor will bump over. Please someone tell me this isnt going to be as painful as i think it will be.
