Maybe the next thread should be: who's worried about how many miles they will get out of their 7.3L Godzilla....

 

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.

 

I'm glad to see Ford got back into the pushrod game as well but they have a lot of catching up to do. For decades GM has been perfecting the pushrod engine. The three shop truck I own are gmc 6.6L gas 2500hd's. The reason is simple, they work...and forever. Yes the 6.2L has had some valve spring issues but by in large, the 5.3L,6.0L,6.2L, and 6.6L are some of the most reliable engines on the planet. The 7.3L doesnt hold a candle...not yet anyway.

 

Are the direct injection 6.6 gas motors from GM proving to be durable with severe duty use like long idles, short trips, etc? Their old 5.3 and 6.0L vortec were the gold standard of OHV truck motors, but I am not too familiar with their 6.2L (which is only used in 1/2 tons and SUVs) and 6.6L.

 

the 6.6L gas has only been available since 2020? How is it proving to be the most reliable yet the 7.3 that has been out for the same amount of time is not reliable? That statement sounds like total B.S. with nothing to back it up. I would choose the simplicity of the 7.3L over a 2000psi direc injection system with higher cylinder pressures any day. GM has been perfecting the pushrod v8 game 😆. Thats why the 6.6L doesn't make as much power and they've known how much the godzilla makes for years at this point. Less power 3.42 rear ends. Sounds like GM is really in the towing game huh?

K.I.S.S.

 

We've had an exhaust leak to deal with on one. I would say the oil consumption of about 1qt every 3000 may iritate some people. Doesn't bother me, and I've not heard of cylinder issues. They run alot daily with service beds and stay loaded down. My guys keep the idle times low, thats a killer for all engines.

 

Hurts the soul doesn't it lol. Think of the 6.6 as Kong and well you know the rest.

 

Maybe they all used AmsOil and that is why their engines failed...

 

Burns 1qt of oil every 3k miles. Doesn't hurt my soul one bit.

 

I would take the 6.2 Ford OHC engine over ANY of those GM pushrod engines, any day of the week. Better power and reliability. Idle time clearly isn't an issue as I had one with 7000 hours of idle time by 110k miles. That truck has now doubled those miles and still works everyday without having to add oil every 3000 miles. The 7.3 makes more power than the GM gas engines and doesn't use a complex failure prone direct injection system to do it. I personally do not see ANY competition there. Voting for Ford with my pocketbook on my last three trucks, not the least bit disappointed .

 

Guess you forgot about all the 5.3 afm issues.

 

Threads for days of the 6.6 gas using oil. Even found some with lifter issues and a few that grenaded.

 

Piston rings and valve guides are going to get worn with higher mileage. Oil consumption is going to increase, it’s normal.
I’ve had more Chevy V8’s than I can count, they would all use oil eventually, but they all were rock solid.
I’m sure the 7.3 is going to be no different.

 

Yeah the 6.2L in my Sierra Denali was certainly reliable, but only until 102k miles when an afm lifter collapsed, spun, wiped the cam, and trashed the block around that lifter. But hey, that's why I'm here now. Still have a 6.2 now, just not from GM .

 

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.
