Truck died on the interstate. Towed to dealership where they find damage to the IPR screen. They replaced the IPR and the truck ran fine. I drove about 150 miles home, shut off the truck and it hasnt started since. Took the IPR back out and it looks fine.They say the damage to the IPR to start with was probably caused by the screen below the oil cooler breaking apart and getting into the system. I took the oil cooler out and the screen was fine. What else could get into the system and cause damage to the IPR screen? HPOP?
