Oh the 300 Inline 6. I loved that motor as well. I just sold my 94 f150 with one and man only issues with that truck was keeping an alignment. The factory radio with tape cassette player finally bit the dust. It had its second water pump on it and alternator but a few other small part here and there. But she would just perform. I drove it daily 70 miles one way for 3 years straight. Only twice it put me on the side of the road. Once I was hauling but at 80 and hit a spot on interstate that asphalt eater machine had not gradually picked up so it was like hitting a curb. Broke the form in transfer case and locked into 4x4 low somehow. I limped it to next exit and had it towed home. 2nd was I somehow didn’t have one of the spark plugs in tight and it wiggled loose. Driving home one afternoon from work and sounded like dodge city on a Saturday night. Some lady actually called the police on me she thought i had taken a shot at her. Thankfully when police arrived and i was under the hood in a suite and tie he said sir where you shooting a gun. I said no sir officer i blew a spark plug. I got it back in and tightened down and headed home. Good motor. Easy to work on and very reliable. I did nothing much but change oil and filter and air filter. Changed plugs and wires as needed. Fuel pumps were no fun but it was my biggest complaint. Went through 4 brand new ones that failed within a week of install. But all else i had dual tanks so made it home. I am hoping the 7.3 will do me well also. I bought it because of its simplicity of design. And a lot of help from people here. So far i have no complaints. I am driving a 2021 CCLB 4x4 7.3 4.30 rear and it gets better gas mileage than my inline 6 did It hauls a lot more weight and the whole family including dog all fit in the truck nice and comfy. Now it only has about 30k on odometer so far so we will see long term. But easy to do maintenance. Air filter was a little stubborn for me to get new one in until i got my glasses on to see what i was doing. It needs a bigger windshield washer fluid tank. Geezers the truck is huge and they allow a small amount to be placed in the tank. I use that a lot on the farm so I keep extra jugs in toolbox. But that’s about all I can complain about so far. It’s a climb to get in bed which I will be fixing as soon as winter gets here with one of those step things under bed. I opted for not getting the tailgate step because of weight. My young daughters are often helping me on farm and it was a lot harder for them to open and close the tailgate with that step built in. Although I might be wishing i had bought that. As they are getting stronger wrangling small squares of hay now.

Now that it has been brought up the Ford 300 and AMC 242 were such reliable durable engines.

Inline 6 engines are great. I had an 4L jeep and my 300 Ford. Just miss them both.

Sorry but I call BS on both stories... This forum would be flooded with posts if there was a real problem with the tens of thousands of trucks Ford has sold with this combo. You found 6.... Bet I can find 6 blown up diesels in the same time period.
complete ignorance.

I dont know why antidotal evidence offered in response to a question about reliability on a forum where this sort of evidence and question is normal must be met with anything but open arms, especially when it is as detailed as it was here.

Before the 7.3 came out, there were LOTs of people here that felt like passing on the first gen of this motor would be the right thing to do since most first gens of anything have some bugs that get worked out at the buyers expense.

Well guess what. The 7.3, 10 speed, first gen 6.7, everything, has bugs that get worked out at the buyers expense. Especially now days.

I appreciate the examples being offered here. I appreciate the members taking the time to list them. If I were contemplating buying, I'd like to know those stories.

I had the option in 2020 to buy a 2020 SuperDuty or a new old stock 2019. I chose the new old stock 2019 because (1) I read enough on this forum about initial problems with the trick 10 speed from people that took the time to post about it and (2) the 6.7 in the 2019 was tried and tested and most of the bugs were worked out CP4 notwithstanding, and the 2020 had an "improved" 6.7 that was not field tested with years of impressions in feedback. Yeah I know the 6.7 upgrades for 2020 were not massive, but how much of a problem with a new thing are you willing to endure when it's in YOUR driveway or on the side of the road?

So I appreciate the antidotal evidence on the 7.3.

Care to share your local dealer's name?

There are nine (9) Ford dealers in my immediate area. VERY few Super Dutys...Basically zero 7.3L versions on lots anywhere.

The claim was 70 customer trucks awaiting repairs... I bet they don't have 2 new Super Duties so I am not sure how naming the dealer helps but Montrose Ford, Montrose CO.

I emailed the Montrose Ford Service Manager asking about these ~ 70 Super Dutys w/ lifter issues (7.3L).

Here is his response.
"Good morning. I am not sure where you are getting your information, but we don’t have any 7.3 super duties here. We sell very few 7.3 liter trucks. Most of our heavy duty trucks that we sell and service in this area are 6.7l power strokes. People love their diesels in this area. That being said, of the few 7.3L that we have serviced here they have been good trucks."

Edit:
Oops, I thought I had the dealer that was supposed to have 70 7.3L trucks waiting for repairs.... Sorry RidgwaySD.
I should of been getting that info from FishOnOne.

@FishOnOne Post what Ford dealer you're talking about (70 Super Duty 7.3L waiting on repairs).
Would love to verify this claim.
