Is buying a 20-year-old 7.3L worth it?

If you can, look for a 6-speed manual. Plan on replacing key sensors like CPS, ICP, and IPR. Stick with OEM parts and get gauges. I bought an ’01 F-250 that needed a clutch for $3k, but I’ve spent $6k more fixing it. That’s just how it goes.

If it’s an automatic, plan for the transmission to go at some point. A properly rebuilt one will last. I’ve got a 2000 F-350 SRW with 250k miles, and it runs great. I added a CAI, Hydra tuner, and next up is exhaust. They’re sluggish in stock form, but upgrades help a lot.

7.3s are solid. I just picked up a totaled ’03 with 104k miles for $8k. People have offered me $10k for my ’01 with 350k miles. My dad’s owned five 7.3s, and none were bad. If you maintain them well, they’ll go 400k easily.

Ask for maintenance records. At these mileages, injectors shouldn’t be an issue if the truck’s been cared for. A failing transmission is more likely. If there’s no service history, I’d pass. Good luck!

Records aren’t always reliable. There are quick inspections you can do—check the oil, inspect for leaks, and look at coolant and filter brands. These tell you a lot about how the truck was cared for.

Fair point, but if they have receipts for a new transmission or major work, that’s valuable info. Always start fresh with an oil change after buying, though.

Absolutely. Also, send in an oil sample for testing. It helps you understand the engine’s condition.

Forget the 7.3. Look for a 6.0 that’s studded and deleted. You’ll get better towing performance and a stronger transmission.

If you want a 7.3, you’re mostly paying for nostalgia or collector value.

If you can afford to keep an old diesel running, you can probably afford a newer one and save yourself the hassle of constant repairs.

Not true. I daily a ’97 Powerstroke and spent about $1,800 fixing common issues. That’s way less than a $1,000-a-month payment on a new truck. Older diesels are more DIY-friendly and cost less to maintain if you’re handy.

Sure, but new trucks save time and are more reliable for daily work. Not everyone wants to spend weekends fixing their vehicle.

Fair, but some people prefer owning their truck outright. Monthly payments on new trucks are way higher than maintaining an old one if you know what you’re doing.

If you’re looking to make working on your truck a hobby, go for it. I have a 2000 7.3 and love it, but show up with a checklist when buying one.

I’ve got an ’02 with 270k miles. It doesn’t need much more than clean oil. I wouldn’t recommend a truck with lots of mods. The 7.3 is reliable when treated like a workhorse, not a racehorse.

I’m a 6.0 guy, but the 7.3 is reliable if it’s been maintained. Look for service records, as they’re often more important than mileage. A well-cared-for high-mileage truck can be better than a neglected low-mileage one.

Try to negotiate the price as low as possible. Assume it’s been worked hard. The market is full of overpriced trucks because of demand, but you can find better deals in rural areas.

I bought my ’99 7.3 16 years ago, and it’s still going strong. I’ve had to replace ball joints and wheel bearings, but regular maintenance keeps it reliable.

I’d take a 7.3 over a new truck. Basic maintenance and mechanical skills are enough to keep it running. I bought mine with 265k miles, and it’s been great. The newer trucks have expensive emissions systems that are a headache.

I got mine for $10k with 270k miles. Needed some basic repairs, but now it’s fantastic. Totally worth it.
