My dad always said “It doesn’t matter what brand you buy, just make sure it wasn’t built on a Friday.”

The most current problem I have heard about this engine is at around 40k the lifter rollers delaminate and take out the cam shaft.

This is a very well engineered engine. There have been zero oil pump failures. Talk with Brian Wolf how far you can push this engine. High quality oil is critically important. There have been some heat treat issues with the cams a some followers/lifters. I have been an engineer (electro/mechanical) 2 and 4 stroke race engine building school and a master mechanic. In the automotive industry we are always striving for 0 PPM failures however, you will always have some failures. Want to get int Bosch's CP4 failures? GM 6.2 issues? I think the biggest failures with this engine have been chassis cab configurations, which would be used in motorhomes etc . Full load from day one without any break in period. The variable oil pump is similar to a Racine hydraulic pump which has been around since the 1930's/40's, very, very. reliable . I could go on and on. BTW I do not work Ford, but have been in the automotive industry for over 35 years. Also the transmission is used on both the diesel and 7.3 engines.

I’ll keep my 300 straight 6 with 140, 000 miles.

Went back and re-watched video. You qualify with stating use a quality oil. Let's start with cam phasers, they are there to provide the low end power while still meeting EPA emission requirements. As you stated good quality oil and proper change intervals and they will work fine. This is not a design flaw. The viariabe oil pump is a great design. Helps with fuel economy while not over burdening load forces on the chain or pump. Oil should flow out of the bearings, as this is how the bearings and journals are cooled. Thicker oil reduces fuel economy and fails to take heat out, hence a variable pump (Racine design) compensates for viscosity changes. Slots between cylinders allows for cooling and expansion coefficients, engineering 101, yes it is a thin wall area, but no expansion compensation in this area will result in many more failures. Gears vs chains, I also prefer gears but, valve train noise is/was a complaint in earlier engines and why we went to high vol chains. Staggered preloaded gears helped but ultimately start making noise also. Heck, we have had people complaining about the pendulum weight rattling in the seatbelts retractor. With all DPF issues and intercooler issues on the diesels this will prove to be a very good service vehicle engine (utility vehicle, ambulances, etc) that have high idle hours and no load, which is terrible for modern emission diesel

Amazing that after all the problems with oil pumps and phasers in the 5.4l triton, Ford engineers still insist on these inadequate designs.

First year or 2 of any engine will be issues it's best to wait 3 years or longer so they can get the bugs worked out of the new engine

[gannonfamily]

I wonder how many of the engines are on the road and what the percentage of failure is. That really tells us the story. And of those common failures, did they get addressed as known? Even bigger factor.

[freddykruger]

Breaking News, Ford teams up with Briggs and Stratton to provide an engine line guaranteed to fail for completely avoidable reasons!

My 2021 F-350 7.3 has been flawless in 17K miles fingers crossed 🤞. I change the oil myself every 3 K religiously! The oil pump is a multi vane design & provides more oil pressure with more load on the engine . Looking for 300K on this engine I’ll let you know when she blows lol 😂

[CaptainLongbeardTuds]

transmission failure is NOT a testament to an engines reliability. we all know automatic transmissions are garbage

[gilvietor]

I had to move my parents from Arizona up to us in Wyoming, I flew down and got a moving van, specifically chose one with the new 7.3 to try it out. Was very impressed, told my wife we finally have a replacement for all those expensive diesels we have owned. Then I find out about the lifters and just WTF FORD

[hunterkennedy]

so, I'm going to eat some crow here and admit you have some valid I do think for most people this engine will last 300, 000 miles at least. I change my oil religiously. so, I'm not worried about the Singular phaser it has. coming back to the head design, yes, the Eco boost had problems, but you have to understand the Eco boost had a lot more cylinder head pressure than the 7.3. this engine was designed for a medium duty truck application to replace the V10. It has forged internals and will be just fine in a naturally aspirated and even boosted applications. still this motor will NEVER be as bad as the 5.4. And most of the 7.3's that were replaced were first year model 2020's that is to be expected with a new engine.... I talked with my uncle who is a master ford tech, and he hasn't seen one 7.3 come through his shop yet with a failure.

We have eight 2021 E-450 series chassis vans up-fitted as Para-Transit buses with the 7.3 V8, have had eight lifter / camshaft failures, one before 30K the other two around 35K
The buses all get serviced, engine oil / filter changes at 3, 000 miles using the recommended 5w/30 Valvoline full synthetic engine oil and Motorcraft filters

[garyhamman]

Dude, these are not design "flaws". They are success. Greed

Full disclosure : I own a '22 Regular Cab F-250, 4x4, 10R140 transmission, 7.3L gas motor, and 4.30 axle. With my current driving habits, I'm only going to put around 3000 to 5000 miles a year on the truck.

I shopped this truck against a similarly equipped '22 Chevrolet Silverado 2500 with the 6.6L L8T motor and the 6L90 6-speed transmission. I ended up going with the Ford because of the Port Fuel Injection over the Direct Injection used by GM (and the known issues with carbon buildup on the valves with GM's direct injection motors of the past).

As far as the transmission (10R140) goes : I have found that if you don't let the vehicle warm up for at least 10 minutes from a cold start (more like 15 minutes in the winter time), that transmission is *very* unhappy about shifting in low speeds (this apparently is a known issue when these trucks are ordered with the 4.30 gears). I realize this isn't a Cadillac so I don't expect these shifts to be butter-smooth... but it was bad enough that I literally thought the transmission was skipping/slamming gears. The only thing I can think that's going on here is : The transmission needs time to cycle enough fluid through the entire unit, or is there is some kind of viscosity issue with the trans fluid when it is at ambient temperature.

Ford does indeed have a ridiculous maintenance schedule on this vehicle. Their schedule calls for a 5W-30 synthetic blend, with an oil change interval of *10 Thousand Miles*. Yea, that's freaking insane and I would never wait that long to change the oil in a passenger car, let alone a heavy duty pickup truck. Even with my low yearly mileage, I'm going to be changing the oil twice a year (so every 6 months).

For the transmission, I plan on filter and full fluid replacement every 2 years. This is annoying because the 10R140 has no drain plug, so you basically have to drop the pan every time you want new fluid. The trans pan also has no gasket, so you get to play the game of scraping, brake cleaning, surface prepping, and balancing the trans pan with RTV while trying to perfectly line up the plan with the bottom of the trans...yay 🙄

My Ford dealer insists I don't need to do either of these things at this frequency, but quite frankly I am happy to spend the $$$ as preventative maintenance costs given the rash of issues that folks are having with the 10R140, and Ford's claiming that an engine that puts off this kind of heat can go 10, 000 miles on an oil service with a synthetic blend.

Thanks for the content!

I have a 2020 F250 with the 7.3 Ford had to replace short block at 17, 100 May of 2022 took 10 weeks for the repair issue I had was rough idle at stop lights had no check engine light to come on but when they put it on machine it was miss firing on all 8 cylinders I have not had any issues since

[howabouthetruth]

There have been a rash of problems with the cam lobes and lifter rollers de-laminating in this engine. This happens with owners who are using good oil with proper oil change intervals ( NOT the ridiculous recommendations by Ford Motor Co. ) Sorry I don't have any video links to offer, but do a search, and you'll see the videos I'm talking about. There's a serious problem going on with the manufacturing of these cams & roller lifters for this engine.

[chrisrossman]

Improper valve lash or valve float can cause the same issue. If the lifter is leaving contract with the cam roller at any point, the valve spring slams the lifter back into the cam and is basically hammering the roller into the cam. This could also be a oil pressure issue, the Godzilla has a variable oil pump. The gauge on the dash is basically an idiot light that trips at 8psi. The loss of oil pressure at higher rpm will effect the backlash. I am not 100% convinced that is a lifter or cam materials problem
