Uncle Tony says Gen III hemi has inherent lifter lubrication problems. Agree?
cuda416 said over reving but I don't think the computer would let that happen. There was too much in his post to quote him. I have an 05 Ram with 88,000 miles, but do mostly highway miles and no real problems yet. A 2010 SRT with 11,000 miles and all hi way also.
That's a fair statement if you accept the default rev limiter is up to the task of compensating for inadequate valve springs etc. I have a 2010 1500 with 180k and no problems yet, other than two busted exhaust manifold bolts. I know at least one person who got a motor replaced via warranty after he reprogrammed it and raced it. Blew it up and flashed it back. I'm sure the dealer knew but he raised enough of a stink when they went back on what the manager had promised, they gave in. It happens. I'm sure not enough to say it's the cause of the problem but people lie and do stupid things.
Again, I don't know what the problem is but I'm just tossing out possible causes. Never claimed to be an expert but I do have quite a bit of experience "debugging systems" and have learned to never discount the "odd" because don't agree with it at first. Occams Razor can be a *****. This could all be simple as has been said about poor materials and de-lamination. I can certainly accept that, but find it hard to believe the factory wouldn't be able to figure that out and call the manufacturer to say "Hey, put more of XYZ in this proportion in the mix"...
The analysis showing the movement of the metal is interesting to me. We all know even the hardest metal has a plasticity to it. This would certainly lead to de-lamination, after taking a pounding, but from a roller? Pound on a bar of steel and it will eventually do the same thing if it's done cold. That's the part that strikes me as odd. Barring something causing the valves to float and bounce the roller, if it's properly lubricated, the roller will NEVER contact the lobe. That's what oil does after all.
Once again, I'll state I am no engine or metallurgy expert, and I am very interested in the final determination, even if it's just bad metal. But wholly cow there's a lot of **** slinging about how "stupid" other people are with nothing more than "because I said" mentality....
This next part is just a general observation....
I also find it telling how many people seem threatened by the smoking man who has a channel. It's hilarious to me how many people gave him crap for not doing things "right" when building that 318. From the get go, it was stated that it was to be an extremely low dollar build to see what they could get out of it. No, they couldn't stay off of their high horses though and put toss their two cents into the well hoping to bring him down a notch.... sad really....
