I have replaced a crap load of cams in them and never seen the stuff ruin anything else, bearings still look new in almost every single engine I have torn apart.

I love how they blame the hemi tick on MDS but there is no MDS on that engine.

Good job blaming the lubrication system for the lifter roller failure even though the early ones and later ones don't have that problem even though they have the very same lube systems.

Only 4 bolts!?!?!?!?! What to do? what to do? Scrap all the hemis I guess, they can only handle a thousand or two horsepower so lets melt em all down into 5.3s!!!! Anyone know these clowns? I want to ask em how many 5.3s they know of the factory built with 840 NET HP.

And the garbage aluminum bearings look brand new after 400,000 miles so they are garbage and we put old babbit bearings in because they are so much better... I wonder if they scrape em down with a razor blade to get the proper clearance also?

Why didn't they pull out the worn out cam and show everybody what a piece of junk they are? Because the cam don't get ruined until they changed the lifter in 09.

I'm so tired of the youtube videos on these engines. All the "experts" that make videos explaining things for us and contradicting each other, facts, etc. Enough.


Facts are stubborn things.

Sorry to resurrect this old thread, but what is considered the "later ones"? I'm looking to buy a new to me used truck and I'd like to have the Hemi. I want to avoid the problem years, of course.

Thanks

Who are these guys?
Cam bouncing on the lifters. work haha
I'm assuming they are from Canada with those accents, correct shruggy
BTW, do some people get paid by someone when they post videos?
If so, where do I sign up whistling
Enough complaining about how some people think and talk blush

I have not seen one past 2013 and only one 2013 so as best as I can tell somewhere in 2013 they changed over. I would also not hesitate to buy an earlier one though, just stick in a 6.4 cam and lifters for a real nice upgrade if they go bad.

They didn't get MDS until cars in 05 and there was changes again around 09. So usually later ones refers to ones after that point.

The problem did not start with MDS, the cams did not go bad in 03-08 engines weather they had MDS or not. And I have replaced plenty of cams in ram 2500 trucks that never had MDS.

Some day I'm going to make me a video of all the things wrong with the LS engines.

I hate to say but those things are tough as nails, at least the ones without cylinder deactivation. We have had several 6.0s in our fleet at work and they have been rock solid. 250-300K with nothing but tune ups and maybe a water pump. By then the van they are in is usually tapped out.

Lol title may seem mean but its not, they do videos on all engines to show any faults with them (by far the worst was a Ford 6.0L diesel torn down by a Ford mechanic that had to deal with them when they were new). This case its an old 2004 with 450,000kms on it (280,000 miles). Watch them tear it down and make your own assumption

Those chevy 6.0s are a joke! The oil pump and oil pump pickup O-ring are both junk and frequently destroy engines. Also the cam bearing likes to spin in the block and you have to pull the engine to replace them as some of them only come in through the back of the block. I can't for the life of me figure out why the 6.0 has these problems while the 5.3 is built the same way and doesn't have the same problems but we replace about 10X as many 6.0s as 5.3s and finding a good used 6.0 is a lot more money than a good used 5.3, it usually saves $1000-$2000 to swap in a much more reliable 5.3 and so far every customer has said they can't even tell the difference in power but MPG is significantly better. Also unlike the Hemi MDS system those newer LS engines with their version of MDS are horrible.

Ok we have had 6 or 8 that were no joke and required zero reason to open the engine. We change the oil via the reminder(7500miles) run them over GVW, idle them way to much etc. They only get the finest whatever they have on the shelf oil also lol. We recently got a ford transit van because there is no chevy vans available new or used really. I am afraid the ford engine will not be near as tough.
