Hello to all. New member, firstish post. I recently bought a 2001 f250 powerstroke crew cab 4x4 with 48,000 miles on the odo and probably 4-5 years worth of idle time in an arctic environment. It was sold to me as needing a new engine however was running well enough to pull itself out of the snow drift it was in and up onto a trailer. I could tell it was missing and the seller told me a shop had said low compression in 2 cylinders. My initial inspection revealed the following problems: cranking time to start excessive (5-6 seconds), idle rough, white smoke all the time (cold, hot, idle, accel, etc), blow by is minimal, no CEL.
Once I got it home I began to dive into the truck. Taking the intake off revealed a turbo that has minor leading edge wear. Valve cover removal and rocker arm revealed 2 bent push rods. #7 intake had bent so bad it was off the rocker, #2 exhaust pushrod was very bent but still partially functioning. Both of those explain the low compression. Injector removal shows 4 reman injectors and 4 stock injectors. The stock injectors had bad bottom o-rings. Some of the reman injectors had old o-ring material lying across the new o-rings. Number 2 and number 4 injector cups were cracked as coolant was present after pulling the injectors. Cracks do not appear to have made it into the fuel gallery as I did not smell any fuel in the coolant.
My conclusions thus far are this: The short block in probably in ok shape based on minimal blow by and good oil pressure unless a piston was damaged in #2 or #7. The heads could still be in good shape except for possible wet stacking causing valve sticking/ bent pushrods. Sticking valves and bent pushrods could have burnt/damaged valves/seats
My plan is to replace the 2 cracked sleeves, replace the injector o-rings, replace the pushrods with a good used set and do a compression test and a leak down test before continuing to tear down the engine or plan repairs.
Any thoughts about my problems, plan, or conclusions?
