This guy seems to have a lack of appriciation for the 6.2L. What is wrong with them. They are on my bucket list when the F-250 aluminum bodys drop in price.
I seem to think the 6.8 / 7.3 is worse from what I am seeing here.

The 7.3L is a pushrod engine like the LSx family and the HEMI's, they've had the same cam/lifter issues as those two engines as well. Other than that, I think it has the potential to be a fantastic platform for hot rodding.

To be specific to your question in the thread title ....
There's not really anything wrong with the 6.2L Ford. Yes - they did have a few engines that had valve springs break very early in the series; back in 2010 and 2011. But that got cleared up long ago. Other than that issue the 6.2L Ford is a stalwart of reliability; they are coveted in many circles. I think the guy in the video has a clear bias against them, but he goes to no effort to describe why. Probably means his bias is unfounded. There are about a bazillion of the 6.2Ls out there in rough field service and rare is the complaint about them.

What is happening in the manufacturing that is causing cam/lifter issues? From what I remember after the 70's cam problems went away and then 2000 on they came back. Is it the machining or issues with the alloys being used?

Could be a ch-ch-ch-ch-CHINA problem, lol.
Supply chain issues. Verifying that the quality of raw materials is within spec is long gone.

Cummins in the last few years also moved away from the flat tapper lifter and has roller lifters (you don't have to adjust lash in hydraulic/roller lifters like you did with the old flat tappet) and wouldn't you know, they're now starting to see lifter failures.

Huh? Hydraulic flat tappets don’t have lash, just preload which once set it’s set…..
I think he means roller lifter failures, like the Hemi, etc.
Keep in mind this is the same guy that says that oil dipsticks should not exist because checking your oil level is unnecessary. I don’t take anything he says seriously.

Did you watch the video? First few minutes. He's a heavy duty diesel mechanic who fixes these engines all day every day, just in case you doubt his creds.
The old cummins needed adjusting every 150k miles.

Roller failure and QC issues on Cummins stuff isn't new unfortunately, saw it with the ISX:
Nothing wrong with a 6.2L Ford!!!
The only possible dig against the early 6.2s is the valve spring issue. My '11 was built in March of 2011. I've owned from 130k to 180k with no problems.
It typically only operates at 6500 to 12,000' elevation and I regularly push it to 5k rpm. Maybe I'm screwing myself but no problems ‐‐ I mention because some claim you're more likely to break springs at higher rpm
The valve spring thing seems VERY sporadic and isolated. A TINY percentage of engines experience it while most do not. Kinda like GM piston slap but FAR less prevalent I'd say <---no data to support that. Furthermore it's far from catastrophic; you just replace the offending spring under the valve cover and continue with life.

Agreed with the sentiment stated here, the 6.2 is a great engine.
