Uncle Tony says Gen III hemi has inherent lifter lubrication problems. Agree?
I think Tony is sound in his own diagnosis and sharing his thoughts and opinions. Right or wrong, his diagnosis makes sense that there could be a lack of oil situation. Sure the delimitation of the cam could also be an issue with the poor quality of Camshafts as described, but that wouldn’t explain the lifter scoring. Starving for oil makes total sense here, again maybe only part of the problem. As he mentioned, maybe add a hole at the bottom of the lifter or maybe even the sides to add additional oil, the push rods are oil through so maybe? IDK. I wouldn’t say he’s totally off base. How would the metallurgical process fail with a roller cam, unless there is another variable added. Poor metal met with poor oiling breaking down the cam. This mostly occurs over the course of thousands of miles, well past factory warranty so who cares run it till it breaks. Like anything else.
