Uncle Tony says Gen III hemi has inherent lifter lubrication problems. Agree?
Here's a thought... is it possible the issue isn't from idling, but rather from over revving? People lie about how they drive their cars when warranties are at risk. Mr. Walsh stated that there was microscopic evidence of "skidding" and "plastic deformation" on the lobe surface. Then later he points out the low spring pressure. Seems to me, that might lead to a condition where the lobes are "beaten" at high revs. This would account for the fact that the SRT motors don't have the problem. Better cam yes, but also better springs, possibly eliminating the "pounding" effect. A roller tip should never cause plastic deformation as far as i can reason, unless it's beating the cam lobe. Hard enough hit, and the oil is squished out (lack of stiction as he calls it), leaving the roller to "actually" roll on the surface of the lobe, which it's not really supposed to do.
Again, it's just thoughts, I don't claim to be an expert at all. The problem with what I'm suggesting off the bat is he found that damage on the lift side of the ramp. Still though, if there wasn't a lubrication problem, then the parts would not show galling since everything would be separated by a molecular layer of oil.
I for one think he's on to something. It makes sense.
