Uncle Tony says Gen III hemi has inherent lifter lubrication problems. Agree?
Could it be a combination of things from all comments here. Poor metalurgy, poor oil technology, lack of maintenance - oil changes, some small design faults, poor aftermarket parts. I dont know? but from my experience when pulling my 5.7 apart the amount of sludge and gunk in that engine its a wonder oil got to anywhere it was supposed to go. I could of nearly filled a gallon bucket of crap. Mine didnt have cam failure but a spun no3 main bearing.
