Crane Roller Lifters OH NO!
Any idea of how many miles are on those roller lifters?
As for the rollers and reliability in general.......one of my friends is a tech at a Dodge dealership for over 30 years.
He tells me failed hyd roller lifters in G3 Hemis is not uncommon.
There are more pieces....... which to some degree means...... there are more pieces to fail.
This came out of a motor with a fast rate hft cam.
It’s always been kinda noisy...... nature of the beast...... but then one day one lifter wouldn’t quiet down.
This style of cam is simply more demanding on the lifters than what they’re capable of tolerating for the long term.
Original /6 recipe for reliability........numb cam that operates fine with wimpy springs...... no hydraulic mechanism in the lifter to fail.
It just makes sense that as you stray farther and farther from that model, with an eye towards higher performance ....... reliability starts to drop off along with those changes, and any added complexity of the componentry.
