Im at a loss right now and so confused. Had a problem with my motor hydrolocking. Egr cooler was bad so i did a bd egr delete kit and also changed out my oil cooler. Also swaped out all the gaskets and o rings and a new themostat. Truck has been fine dor a week now but today it hydro locked on me. Does anybody have a idea what it could be. Im not loosin any coolant and hasbeen running great. This is my last resort before payi.g out the *** at a shop.
