OK so the lifters aren't the problem... can this be prevented by using high-quality oil? Would there be any benefit to running higher-end stuff like Brad Penn or is something like Valvoline Synthetic enough? Guess I should look at what the factory recommends...
I believe it's a issue with the material the camshaft is made of.....I have torn them down, and noticed the metal starts to "flake" off the lobes in little peices, then it's only a matter of time. The cams also appear to be cast iron, not steel
