Ford F250: Driving down the road pulling a trailer doing about

Customer Question

Driving down the road pulling a trailer doing about 45 to 50 mph and 2012 Ford F250 with 6.7 Powerstroke (116,000 miles) had a vibration and stalled. Opened the hood and oil all over. Would not start again so loaded it up on a trailer and hauled home. Pulled the following codes P20BA "Reductant Heater A Control Circuit Performance", P246E "Exhaust Temp Sensor Circuit, P06EA "NOx Sensor Processor Performance (Bank 1, Sensor 1)", P0069 "Barometric Pressure Correlation". None of these appear to have anything to do with the obvious problem of the oil leak, but would there be anything that would keep the truck from starting? The starter is trying to engage the motor, but the motor will not turn over. Tried to manually move the crank but cannot, although it does not have a center bolt to put a breaker bar on but 4 smaller bolts so maybe not able to apply enough pressure to get it to move. Temp gauge did spike after truck stalled but no other lights came on, ie, low oil pressure light or wrench light, either before or after stall. Truck ran fine before but did have a CEL for the DEF heater that would come on intermittently. Is it possible for the engine to seize up that quickly with no prior indication of catastrophic engine failure?

Yes it is quite possible for the engine to seize and not turn over, and happen that sudden, we have seen quite few that have dropped valves on top of the piston, this destroys the engine.
