In the ones I've torn down, it appears the cam lobe starts to fail BEFORE the lifter, you can see metal flecks coming off the lobes. I believe the camshaft material is to blame, (soft) a new camshaft from chrysler is like 85 dollars, what does that tell ya?

I would really like to know, but from what I've seen of these cars, taking a fairly quick look at the parts that came out (no long inspection or microscopes), it's the lifters that go south. We've caught some real early on (current one included) and the came shows only normal wear pattern where the rollers roll. Once they start to not roll, then the cam starts to wear away. Had a cam lobe once that had a roller groove about 1/4" deep. Would help if the guys would tell me earlier when the engine starts to make noise, but they have other concerns on their mind. lolol
