Started with a cylinder 1 misfire code. Went through natural progression of diagnosing the issue. Changed spark plugs, coil pack, injector, as well as a compression check of the cylinder. I had to remove the valve cover and turn the engine over without starting it, to see that the number 1 cylinder intake valve does not open as it should. The lifter has flattened out the lobe on the camshaft. There is no excuse for this other than faulty parts installed by dodge on a terrible system. The camshaft lobe should not be flattened out at only 77,000 miles. I do not miss oil changes or take short cuts maintaining the vehicle. why there is even a MDS system on a 6.4L engine is beyond my comprehension. I'm not sure who the genius over at Chrysler is that decided there needed to be an "ECO" mode on a muscle car, but something needs to be done by the manufacturer.
