Uncle Tony says Gen III hemi has inherent lifter lubrication problems. Agree?

Didn't you allready see the picture of the cam lobe missing peices of metal with a perfectly intact roller allready posted in the thread? I have had a boatload of 5.7s in my shop for cam replacement, there is ALLWAYS bad lobes with a otherwise perfect roller still rolling on it. The lifters fail AFTER the cam

Fact is camshafts or either cast or ground on a solid billet. What happens during a failure is another thing altogether.

The cams, whether Mopar, Ford, Honda or any other USA manufactured brand all come from one of two companies...CMC or CWC. And there are only a couple different materials and heat treat procedure for every cam made. Tried and true formulas.

The LS I believe oils the roller and the Hemi does not. The Johnson lifter introduces pressurized oil to the roller via a drilled passage as I see it. That oil makes the difference.

I understand what your saying, but 5.7 cams are cast, they are not billet, and the material they are cast from is the issue. It has nothing to do with the lifter, the lifters fail after the metal crumbles or starts "delamination" for lack of a better term.
 
And @Krooser, you stated the LS oils the lifter roller, so how does that explain the LS cams fail also just like the hemi? I say its because its NOT a oiling issue, it's a poor casting issue. Same reason the SRTs dont have the failure rate of regular 5.7s. Its because the DO have a better cam, and its oiled the same exact way as a 5.7......see what I'm sayin?
 
From what I'm seeing....if you order new Mopar G3 lifters the P/N defaults to Hellcat lifters period!

Did Mother FCA figure this thing out?

My question is, before I put my 2014 in my 1968; which is better, Hellcat or Johnson?

I'm sure you didn't realize it but "Mother FuCA" is funny.
 
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.
 
Sounds like NON routine maintenance. And/or inferior quality oil. Granted, once any engine hits its"high mile" mark, they seem to start sludging up. But, overall, I would be inclined to agree in a perfect storm situation.
 
Sludge is also a byproduct of short runs not letting the oil to get hot enough to burn off the byproducts and poor maintenance. My srt Challenger has an oil temp. readout and I always run it till oil is over 212*.

I think you're on to something there , all my cars are high mileage and when taken apart they are super clean no sludge , they run a min of 100 miles a day , short trips where the engine never gets hot enough to burn off crap is an engine killer , that and cheap oil
 
I had 80 Civic that I drove 50 miles from work and drained oil when I got home, eat dinner and went back into garage and finished oil change. I also kept filling filter till it was saturated and then installed it. 205,000 miles but clean inside. Although I never had to take it apart.
 
Tony just posted this "revisited" video so I thought I would bring this back up to the top to give new argument material. lol

 
Nope, he is a moron, and if you believe this bulls$%t explanation, your either a idiot, or a moron also.

I have 2014 Dodge Ram 5.7 with 65,000 mi. on it and and a slight ticking sound at idle. It runs absolutely perfect right now except for the tick. At what point would you recommend repairing it and what do you charge for the repairs?
Thanks, Steve
 
Wow. I have to totally agree with racer43. That was the absolute MOST scientific study ever(REALY!). Gee, after an hour on the phone with one of the most well known gen 3 builders(hour of badgering?), said builder agrees with uncle Tony. Idk, I'm no ******* expert. I've seen alot of these failures. I posted pics earlier in this thread. And posted my thoughts for debate. He can suck wind.
 
They changed the lifter design i believe to a larger needle bearings in the later years.
 
So I happen to own 3 of the gazillion, 200,000+ mileage gen III hemi's on the planet. Have a 4th in R&D about to make 1000 crank HP.

Can't say I see these in any way design flawed. Especially in comparison to an LS, or a coyote.

I don't see Rob Goss having issues either.

When Chrysler was developing the G3 they consulted with Tom Hoover on the design. He recommended raising the cam in the block to improve geometry. Too bad the father of the Hemi isn't around anymore to ask his opinion.

Hmmm......who to trust? Mr. Hoover or King of the dirty low buck 318?

If there is something inherently wrong with lifter lubrication, it would probably entail a drastic revision and an admittance of guilt. Not good when there are millions out there. I have to believe FCA knows why they are failing. So far, they seem to be remaining silent except for now using "hellcat" lifters in ALL engines.
