New member. 2018 2WD Crewcab w/7975 miles. Green Diesel Engineering programming. Truck runs better than it did before I re-programmed. No turbo lag. I am adding an Amsoil bypass oil filtration system this weekend. Does anyone know of an oil blow-by catch system for the 2018? Has anyone experienced any problems with the 2018 2nd generation engine? If you have, what were they? And, how did you fix them?
