The 7.3 gasser has been around a while now. There seem to have been a few small patterns with certain failures. I can't think of a single massed produced engine where that is not true. At this point, it seems to me the 7.3 is in the upper echelon of performance and reliability for its class. I would choose it over the others in its class and run it with confidence. I'm glad to see Ford make a big block pushrod V-8. Great match for an HD truck in my opinion.

All BS aside and F-ing with you guys, the 6.2L is a great engine. It's been around for a while though and they worked through the bugs. It had valve spring issues early on, lots of cam phaser issues and misfires...at least thats what comes to mind. So I would agree with you, at the moment, in the Ford platform, I'd rather the 6.2L than the 7.3L. I know the direct injection is a concern for many but it's not like it's new tech. If your designing an engine and want to be able to manage fuel at higher compression ratio's, you would want direct injection. The higher compression provides a much broader torque band, which is felt when compared to the old 6.0L. We haven't personally had any issues with that system. As a business owner, It came down to cost, I was able to get the gm trucks for much cheaper. That said, I didn't even consider Ram...been there done that...hot garbage.

I do not see any reason to not choose the 7.3 and this silly thread is proof as to why, Not a single actual failure reported, the 7.3 must be awful after several years in production and nobody is here complaining... My 6.2 was a 2012, only the second year of the 6.2 in the SD and like I mentioned, our son is still driving that truck with nearly 250k miles and thousands of hours of idle time. I never even changed the plugs, maybe he has... Never gave either of us a seconds concern and the PO's service records revealed nothing odd. I considered a 6.2 6 speed ruck for my '22 but even by then, there were not any real 7.3 issues and clearly, there still are not. My 7.3 truck is doing great. More power, better mpg than the 6.2 truck and rock solid 67k miles in, not a single concern or repair needed. I share your opinion of Ram but I also swore of GM a looooooong time ago because of issues. Besides a GM truck just would not hold up to my use, and they are fugly...

I think you guys have to consider the fact that most people that have had these failures are not on this forum. Not saying they don't read it, but the chances of someone wanting to chime in here to tell the world about their engine issues is slim. Like mentioned before, you have to have thick skin around here. Just because it's not on this site doesnt mean the failures aren't real. I wasn't a member back in 2019, but when Ford purchased my f250 back, I didnt share anything on this site.
Here's mine a V10 self inflicted, I knew it was ticking louder.

The Ford 6.2L Boss is bullet proof, camphaser issue claim is BS. Almost any shop will tell you they’ve never even had to work on the Boss engine. Even FordTechMakuloco stated in a video he’s never seen the inside of one because they never need work.

People used joke on the 6.2 section that the reason why it's so quiet over there is because there's never any issues to discuss. Seems to be one rock solid powertrain on the ford 6.2 6spd.

Show us "lots of cam phaser issues."
No credibility again.

I remember when I bought my 2012 with 6.2L gas engine. In those days, there were about a half-dozen valve spring failures and on the forums the sky was falling. Everyone with a 6.2L was freaking out about their engines. Now 12 years later, that engine is considered one of Fords best. I put 100k on mine before selling it without a hiccup. That is the nature of the internet. From politics to trucks, little things get amplified to the point of hysteria.

The 7.3 is so reliable that this “7.3 failure thread” has turned into an oil, 6.2, and everything but a 7.3 failure thread.
The 6.8 makes more power than the 6.2, it’s probably lighter, less expensive to produce/maintain and is based on the 7.3.
I think Ford should have just continued making pushrod engines like GM. A dual plug, SOHC is unnecessary for making the amount of power the 6.2 makes.

Based upon current F250 ordering, delivery and pricing, looks like I'll have to hold onto it a little longer.

So you are telling us you are new to internet vehicle forums... The truth is exactly the opposite of your claim. People come to internet forums SPECIFICLY to complain about issues they have had, some even looking for answers, most wanting just to vent. The forum is full of these posts. If there was a problem it would show up here before the dealer even, guaranteed. The failures just are not happening, not at any rate above what is normal for any mass produced thing.
