Have a 2011 international pro star with a Cummins ISX 445ST. Check engine light was coming on showed crank case pressure. Changed that I have a lot of blow by. Truck runs great only issue is when loaded (haul steel coils) check engine light comes on & I have to shut the truck down. Engine has never been hot I’m losing NO antifreeze or oil.
