The change interval on the 2V is also 60k and not 100k. Gotta get your facts straight if you want to prove a point.
my 2022 f250 7.3 is my new replacement fir my 2005 f150 5.4 and if I could go back to 2005 I would have bought this truck again. No regrets at all as my 5.4 really runs! I pull a 20' enclosed trailer fully loaded, sometimes an open trailer and a slide in camper, or some really heavy loads. My f150 has only gone over 5,000 miles for an oil change one time and it currently has 124,000 miles
now having the 7.3 I can't believe what this truck will tow! I had the camper in and towed the open trailer over the holiday weekend and there is almost no difference between loaded or unloaded. You just don't know it is all back there!

My 22 250 4.30 has been good so far with 12k on it. Towed my 12k camper, and a 15k trailer / mini excavator and it handles it fine. I have 35's on stock suspension. Coming from a tuned 6.4 I do miss the power of a diesel driving empty and with a trailer, but mine has been reliable so far no trips to the dealer since I've picked it up. It's such a relatively simple motor I see this being solid for the long haul.

Like anything If you maintain it it will serve you well. I just got rid of a 2008 expedition with the dreaded 5.4, and it had 200k on it minimal issues outside of cam phasers, but that was easy to do in the driveway.

I’m watching 7.3 threads for high mile engines. Not seen any yet, i suppose most like myself that do 50k a year just go diesel. Seems like an ok motor so far.

The machined slots between the cylinders which has a record of creating head gasket failures in some other engines is my biggest concern. If you look at the shiny surface on both sides of the machined slots, there's very little sealing surface between the head gasket and the block.

We'll see I'm at 85k now after 20 months. So far so good.

I haven't seen any reported issues regarding head gasket failures on 7.3L engines. Not one.
Please report back if you find any.

I can't find it now but I was reading yesterday about one guy that has 350k miles on his and another with 250k. I'm sure there are a few high mileage 7.3's out there by now.

I've been watching for reports of issues since it's 2020 release.

1. Initially (2020) there was the ignition coil wire issue. Ford redesigned the ignition coil wires. Problem solved.

2. I've read about a couple lifter failures. Doesn't seem to be a wide spread issue at all. Like I've only read about 2 or three reports of this issue (2020-2022)

3. One report about a front crank seal leak.

I'm sure there are some other examples people can find out there. I'd love to know how many 7.3L have been sold since 2020?

I'm convinced the 7.3L is a very very reliable, solid motor. Ford designed it old school, solid, beefy and simple. Port injection, push rod, 6 bolt mains, iron block, over sized skirt, over-sized head bolts, forged crank, chain driven oil pump.

The only thing I don't "like" about the design is the seemingly lack of iron between cylinders...small head gasket sealing surface (due to the coolant slits). BUT, there have been zero reports of head gasket failures. Those coolant channel slits are there to carry away heat between cylinders. Heat is a head gaskets worst enemy...so real world performance is proving the design is working in the 7.3L's naturally aspirated application.

I'm loving my 7.3L...only 6,200 miles so far (daily driver), but absolutely 100% glad I chose the Godzilla for my Super Duty. No weird noises, nothing.

My 2018 5.0L F-150 had an annoying 'throttle off' chain rattle when cold. Very common. Had since day 1.
My 5.0L also had a VCT solenoid failure at 60,000 miles. Fairly common as well. Not hating on the Coyote...very very good motor overall. I've owned two (2nd Gen Coyote in Mustang GT) and the 3rd generation in the F-150. I'd buy another 5.0L no question.... So fun to beat 6.2L Camaros and 6.4L Challengers with a 5.0L Mustang (Go Ford) 😀

I'm hearing nothing about 'common' Godzilla issues. Nothing.

Can't say that about the 6.7L Powerstroke (as good as that motor is).
Things I've read about concerning 6.7L issues:
* Upper oil pan leaks ($)
* Radiator Coolant Leaks
* Turbocharger failures ($)
* DEF tank issues / sensor issues
* HPFP failures ($)
* EGT Sensor Failures
* EGR Cooler Clogging ($)

Pretty cool picture, thanks for sharing! I don't understand the engineering on automotive engines as well as a lot of you guys, but to me the trade-off between thinner cylinder walls and better cooling sure seems like a good idea to explore. Surely Ford tried their best to destroy a bunch of these on a dyno before going into production to find the best combination of cooling / wall thickness / gasket longevity, right? I agree that real world proof in lots of high mileage engines will tell the real story, but I'm crossing my fingers and hoping this 7.3 gasser turns out to be another legendary engine for Ford, similar to the 7.3 diesel.

hate to ask, but what’s your mpg and what kind of driving do you do, your close to my yearly mileage. I do 50k a year, tow 15k maybe 3 or 4 times a month at most but my truck has about 1000lb of tool and equipment. My trucks mpg shows an average of 16.7, even with idling at lunch. Been doing some figuring and there is a pretty big fuel saving at current fuel prices if a 7.3 would average at least 13 mpg for my situation.

I do mix driving but alot of highway, when at the job sites it's mostly off road and when at the 5th wheel it is off road. Truck always has 1,300#+ in the bed, when towing the Wolverine X4 @ 3,000#.
I misspoke the truck only has 84,100 but after the new year I'll have a 3,000 miile trip to make.
As of this morning total miles since new pulling the toy. I set it up in the truck towing menu to records it once hooked up.


When it was at...50,426 miles ÷ 3,80.17 gallons of 87 octane = 13.26 mpg of combined city/ highway/ long idle time on job site, towing the toy (3k) roughly 24x a year.

From my 50k thread, there is misc road trip mileage in it...https://www.ford-trucks.com/forums/1...l#post20352799

At the end of the year I'll go through the mileage book and get the year end #s and start a new mileage book for 2023.

I see you have the 3.73. Also what’s with the engine light? Just where truck isn’t started?
