the ford 7.3 sounds to me like very bearing on the front of the engine is about to explode like a hand grenade. I have also noted there is a very different level of noise depending on the particular truck at idle, one has the bearing grenade sound and another could have way less of it.

Huh?


Are you referring to single vs multi shot injectors?

My 01 F250 only has 198,600 miles. I don't figure I'll ever have to shop for another diesel, unless this one gets totaled in a crash. Does what I ask of it and only thing I've had to do under the hood is a water pump and GPR. Although I did also have to put a tranny in it some time ago. Apparently the early 01's had a manual diode, whatever that is, that caused the tranny to loose 2nd gear. Exactly what happened to mine.
Are the new diesels much quieter? Yep. But mine is paid for...and doesn't need DEF.

420k and counting on my early 99, 6-speed manual. I spent the dough last summer to rebuild the turbo with a bigger turbine wheel and billet compressor wheel, and a programmer. Towed the 12k boat+trailer twice to the top of Vancouver island, first stock, second with the programmer set to 20hp tow setting, and modified turbo. Night and day difference; no downshifting on the lower island's rolling hills, and big power pulling the hills on the upper island. Stock I was in between direct and overdrive all the time on those mild rolling hills.

Stock it had less poop than a 7.3IDI with aftermarket turbo. That's not much poop.

It is a mix of lots of complicated parts, but generally they're reliable and easily diagnosed. Every 7.3 owner has a cam sensor and 10mm wrench in their glovebox, and every 7.3 at some point needs new glowplugs and injectors, and some top end oil sealing and fuel bowl rebuild work, none of which is difficult. My injectors are stock at 420K...I'm entertaining a swap but will see how this tow season unfolds. Will probably do some compression/leakdown checks before swapping injectors. I bought the truck cheap, have put in some money/effort on springs/shocks/brakes, engine top work (fuel bowl and high pressure oil), and some comfort items (soundproofing and better seats) and now it works great and doesn't owe me much.

It doesn't take much work or modification to harness the big 7.3L displacement and blow the pants off of any non-variable-vane single-turbo 5.9 cummins, of any configuration. Big 5.9 power with a single turbo is certainly available, but you can't have that cake and eat it too: low rpm power is replaced by clouds of smoke. Different story with the variable vane turbo on the 6.7 cummins; that one is a monster.

It's kind of a shame that gas engines have gone from late 70s 7.5:1 low-compression hot constipated big blocks (454 and 460, carbed and fuel injected) to high-strung fuel suckers, with zero reprieve. GM's 8.1L was getting close to sanity, but it too was constipated by poor head port design and engine air/fuel programming. Ford's new 7.3 gas should be a welcome change back to real big block gas power.

Diesels with EGR, SCR, Exhaust Filtration and such are non-starters for me. Way too much drama. Next truck will be big block gas, old or new. If old, the engine will be modified to address poor compression and quench and increase airflow. A 454 or 460 making legit 400hp at 4500-5000 rpm should be a monster.

Not since the recall on them. They seemed to have fixed the issue.

could never understand why Ford, when it bought Volvo, didn't use the Volvo diesel, long considered the best marine diesel.

I have 2 friends with F350's with the 7.3 one has 300K and the other has well over 500k on the motor. Neither of them have any desire for a modern diesel and they both love that old 7.3.

Personally I am a year in and 15K miles on a '17 model year 6.7 and don't have anything to complain about as the truck and motor put a big smile on my face every time I get in it. The modern diesels do use DEF. Mine uses so little DEF it's hardly a concern or expense worth talking about.

Compared to the Cummins inline six it makes much less power and is less durable. I still have one on the farm, but I sure wish my ex hadn’t wrecked the dodge.


Chuckle chuckle chuckle. Cylinder kits? When will I need them? My injectors were replaced under warranty at about 60,000, but the new ones are fine. I did replace the water pump at 250,000, but it still has the factory heater and water hoses.
A cummings is OK, but I can't drink a bottle of beer in one without knocking my teeth out.
You guys sucked me into mine is bigger than yours. Chuckle chuckle, ain't no winners here!
