Who’s still using a 7.3 diesel truck

2000 F350, 7.3 PSD, 4R100, 224K, CC, LB, DRW.

All Original; 12,000 Warn Winch/CG.

New technology will always come with baby teeth, but just from my experience.
3 years ago new DPF was $3000, while cleaning shops were rare and DIY cleaners not available. Also lack of driver education, when aborted regenerations create cascade of troubles.
Now aftermarket DPF cost $600, you can buy monitoring scanner for $49, plenty of DPF shops around and DIY cleaners are not needed, when you monitor the system work and accordingly.
The 230-250 HP 7.3l is slow and gas guzzler comparing to "not so new" 6.7l.
I can only wonder what newer diesel will bring.
My huge Sprinter van delivers 22 mpg, when the engine introduced 4 years ago in Europe delivers even more, with more HP.
Can we expect 25 mpg from new Powerstroke?
Bottom line, I am not looking back to 7.3l and I am not picky about pollution.

Early CPS were very bad, oil cooler leaks, ATF cooler inside radiator, turbo pedestal orings, maze of sensors who can fail at any time.
Never have been stranded with them thought, although leaving oil trail with leaky oil cooler can get scary.
Not engine-related, but wheel sensors and ABS sensor on rear differential. Sold both truck with over 300k miles on each.
I remember Adamis had to drive like 2000 miles on 7 cylinders when his injector failed.

You're like a big bowl of Christmas cheer with this post...

I often tell my wife, she can burry in my 2001 Jetta TDI (345k miles and still going strong) that parked in the bed of my 1999 7.3. The newer Diesel engines have more power / performance but they are very complicated and very expensive and the emissions when they go will cost you a fortune.

I think the 7.3 is the pinnacle of Ford diesel performance pre EPA strangling the industry. They will be very much like Muscle cars pre 1976 before the EPA strangled those as well. I also think they will be show trucks and collector trucks in a decade or two. To be honest, I think Diesel pickup trucks are on a limited lifespan. EPA regulations and the complexity / cost plus the industry moving to electric means 2021 diesel trucks will be possibly the last generation or at least the second to last generation. I see hybrid trucks with small 4 cylinder turbo'd engines and 4 wheel electric motors with midsize battery packs being the future.

That being said... I've probably gone down the path of mods on my truck further than most (though not all). To list the things my truck has...

1. Alliant AC Single Shot Injectors
2. KC300X Turbo
3. Hyradtuner
4. Upgraded Bellowed Up-pipes
5. Banks Torque Converter
6. Banks Exhuast Brake
7. Banks 3.5" Exhaust minus the CAT
8. Upgraded T500 HPOP
9. 6.0 Tranny Cooler
10. Airbags
11. Upgraded Alternator
12. Upgraded S&B Intake
13. Torqlift Tie Downs
14. Torqlift Super Truss
15. Gooseneck Hitch
16. Amsoil 2 Stage Bypass Oil Filter System
15. Inline Tranny Oil Filter
16. Patridge and Pear Tree...

Truck runs fantastic now and pulls hard and fast unloaded. Towing camper plus cargo trailer (~9000lbs) on 6% grade is no problem. EGTs have dropped at least 200 deg if not 300 deg for same load. Making now 30+ lbs of boost versus 20lbs previously. I only have two future planned upgrades in mind, a Mishimoto Intercooler and 4" exhaust to drop EGTs further.

In short, if you get ahold of a clean 7.3 in good condition, I am convinced it will be a highly sought after classic if it isn't already.

Still chugging along in my 2002 f350 PSD.

7.3 diesel isn't going away anytime soon.

I have had mine for 3 years, upgraded from a f250 with a 5.4 in it. Had to replace the bed and do a bunch of work to it due to PO neglect.

The shocks got upgraded to Rancho 9000's and I have airlift 5000 bags on it with upgraded overload bumpstops.

Just had to put a new clutch in it at 236K, went with the Southbend HD clutch so it should hopefully last another 200k.

Oh, forgot coolant reservoirs who deteriorate at about 10 years mark and alternators. Those were easy to replace, although my coolant reservoir start to leak on desert, 250 miles from Ford dealer.

Ole Frosty keeps chugging along, I am looking at 280k miles (bought it with approx 190k) over 10 years ago for 8k and 90% of those miles are with the TC. I have replaced the alternator, coolant reservoir, parking break cable, and on my 3rd set of BFG’s. Added Torklift upper and lower stable loads that’s pretty much it. 4th gear (stick shift) occasionally slip out of gear sometimes :(. Also need some batteries soon.

I had breakfast with a good friend yesterday and he just got his 7.3 out of the shop.

He said guilt was getting to him so he had the glow plugs (three of which there was nothing left), I believe the controller and new injector O-rings.

The engine itself has never been touched and he just passed 400,000 miles.

had a 1971 7.3 would tow anything you hooked to it, truck camper and walleye boat from ohio to wis just great.
