2015 Ventana LE 340 HP Cummins, Freightliner chassis. We have had the intake air filter saturated with water on two occasions. The intake duct is high on left side. The first time we were camped overnight during a high wind rain storm blowing into the intake. When we started the engine we had lots of smoke and no power. We were able to nurse the unit to a repair shop where they found the intake filter full of water. The second time we do not know how water infiltrated the filter. We were not in any rainstorms. It has been two years between incidents and about 30,000 miles. There is a duct bill drain in one of the 90 degree elbows in the intake duct about half way down the duct. I checked the drain after the first incident and it was clear. Wondering if anyone else has had this issue??
