2009 5.7L 146,022 miles. Exhaust manifold studs, about to replace broken ones for the 3rd time. Fuel pump replaced at about 95,000 miles. Sparkplugs twice so far. Oil changes often, and on time, every time the reminder goes off on the dash. That's it. So far so good. I cannot complain. I am considering installing new injectors. Not sure. Fuel economy is now at about 15 MPG. Running studded 20" winter tires recently on a 400 mile trip.
