Original owner, all stock 2015 2500HD WT 6.0 gas 190k miles. Cylinder 3 exhaust valve tip almost gone. Engine developed a low noise valve tick on start up and idle, 3k miles later, louder and at all rpms. Intermittent (twice) P0303. Removed valve cover, rocker arm and observed damaged valve. Roller lifter and cam journal showed no signs of damage. Of the eight valves, one destroyed and three others showing wear( pic 3) Inspected passenger cylinder head valve bank, no signs of wear or damage. Oil stain seen through exhaust port. Informed GM and assigned case #9-5190338716. The truck has been a solid performer and provides great service. The short years and high mileage may indicate future issues with valve lots that may be below specification. My plan is to replace all valve parts including lifters. Should GM want to inspect these parts, I will make them available upon request.
I was on another forum and people were posting their mileage on their newer trucks and one guy put almost 50,000 miles on his truck in a year, said he had a long commute. I thought...Jesus that's a lot of driving. But then again these are trucks, people use them for work. I know a guy who is in the hvac business and he's told me that it's not unusual for him to drive 100 miles down a highway, get a call from his boss, and have to turn around and drive another 100 back to pick something up. I have friends that use their trucks for plowing, towing, work, commuting...all in one. Personally I use mine just for commuting...80 mile round trip five days a week. Throw in another 100 miles on the weekends. Easy highway commuting. But I know some people use these things for a lot more, I'd like to hear some of those stories to kind of see what these trucks can handle.
