Everything to know about the 6.9/7.3 idis

[@rc5693]

Might add on the 6.9, if you have all good glow plugs run a solid state glow plug controller, have good batteries and a gear reduction starter to spin it at 300 rpm and follow ford recommendation for full throttle to start below 32 degrees which will also advance pump timing they actually start quite well

[@savage_heck5713]

Good advice!

[@papabigballs3288]

Better advice: bypass the glow plug controller and route a push button to your dash area. That’ll save you having to replace 8 glow plugs when the controller decides to have a mind of its own.

I have a 7.3IDI in an ambulance camper (89 E350) and I appreciate all the info I can get about maintenance and operation. It’s a great engine!

[@aaronkeiser6349]

A very Honest and truthful view of the ford IDI. This is coming from someone who's daily drives a NA 87 T19 4x4. The problem i've noticed from many used IDI trucks is they change hands and maintenance is unknown since the Odometers roll over at every 100k. You don't know if the motor has 100k or 500k. You'd hope there's service records but most don't so you're just replacing stuff left and right. It's always good to write dates on the fuel filters and oil filters and really anything that's serviced as a reference. One thing I will say is I love/hate the ZF5. I'm in a group on FB and literally every other post is someone cracking the case on those transmissions. Whether it's the belhousing area or the rear case by the t-case. Everyone wants big money for a used ZF5 transmission(500-800-1200$). With that being said i'll keep my dime a dozen T19 with 3:54's and 35" tires.

Great video and quick response. I commend you for answering comments and being involved on a personal level with your viewers. I appreciate you're knowledge and input.

[@ColtWR]

Always try to help when I can!

[@subshooting8414]

Thanks for the super fast response!! Thanks for all the info. I'm looking forward to working on it. It's a diesel copy of my first truck I ever owned.

[@ColtWR]

That's awesome!

[@tylerb8179]

Great video, and info for the IDI engines, and trucks! I would love to see an up close walk around of your IDI, thanks! Would love to be able to get an IDI of my own someday!

[@ColtWR]

Will do!

[@seijirou302]

Wow I've never seen a user request video fulfilled so fast. Hope you blow up man, I enjoy your content!

[@ColtWR]

Thank you!

A properly maintained 7.3 idi will start just fine in any cold weather.

[@PapaMurph-dg6gj]

I’ve had good luck with Classic Diesel Designs in Texas as well. Really underrated motor and chassis. Excellent work trucks.

[@ms.carroll5574]

I second them. Right in my home town

[@raycecil4643]

A properly tuned IDI with no air intrusions, a healthy glow plug system, and a healthy starter/battery cables will start in below freezing conditions as reliably as anything else.

[@ms.carroll5574]

I would also like to add Classic Diesel Design out of San Antonio for a IDI source. I drove on a long road trip in a turbo 7.3 NA idi 5mt in a 5.13 geared F-Supoerduty flatbed 2700 RPM highway not terrrible on fuel just loud.

[@jamesmooney5348]

Dang after watching this, I almost want one now.

[@strokedmule3838]

Would love to find a good idi truck that hasn’t been hacked up, they will run on just about anything. tough old trucks.

[@grahamgeiger3206]

My grandparents bought a 94 f250 4x4 7.3 factory turbo 5 speed brand new. It's been a great truck and has plenty of useable power but one thing I'll give a 5.9 over the 7.3 is even for being mechanically injected simple design the underhood is way less inviting to work on. I know they aren't that bad but the 5.9 is way easier to work on.

[@ColtWR]

I'm with ya, the 5.9 wins that battle

[@mick5740]

Enjoyed this video !

Nice dog. Heelers rule.

great video!

I've got the same hat!😂

[@wadetate6459]

I’ll disagree with the idi trucks outrunning a turned up first gen VE truck. My dad had a intercooled 93 5 speed with a turned up pump. It would out-pull everything but a 6.7 Cummins/powerstroke. It made 320/1000 uncorrected in Denver on the stock turbo. He put 200,000 miles on it like that. He used to do 70 mph up Eisenhower and veil pass at 25,000 combined. 3.54’s + 4th gear. A idi is a good truck, but its $15,000 in parts to make one do that. A turned up ve pump is $1500 and a luk heavy duty single disk is $300

[@ColtWR]

1000lbfts on a turned up stock ve pump????

[@wadetate6459]

@@ColtWR I’m seeing several VE trucks on KZbin making 400+/1300+ on pretty mild VE pumps and something like a he351 or a s362. Your probably looking at significantly more money into a transmission at that point.

[@dieselwrench3621]

I have a 86 for F250 6.9 that’s been sitting for about 2 years, and I was wondering is there anything I should be concerned about after sitting this long? I already drained the old fuel and put new in before starting it. Thanks

[@ColtWR]

Not in particular. Fire we up and see what leaks

[@Austinsairplanes]

My 1993 f250 7.3 idi only gets 10-11mpg, I have replaced the IP and the injectors twice.

[@gavincarroll2553]

I took mine up the mountain and i was on the floor all the way up never broke 190 idk how

[@ColtWR]

It takes horsepower to create heat lol.

[@gavincarroll2553]

@@ColtWR it also never broke 25 mph up hill

[@GlennInLaguna]

Thinking about buying a 1994 School bus. How can I tell if IDI or PowerStroke?

[@ColtWR]

The easiest and quickest is the oil fill. If it is up front and center it is an idi, the powerstroke is on the passenger valve cover

[@NHamel123]

Why does every welder name their dog "Tig?"

[@noah_loans]

Is the oil cooler 6.9 the same as oil cooler on 7.3 idi?

[@ColtWR]

Should be yes

[@jadinzack9271]

What kind of oil pressure are you getting on a stock 6.9

[@jadinzack9271]

i only get 40-45 psi on the highway

[@RickSherrin]

Can you put a 5 speed out of a 92 7.3 in a 6.9 idi. Tks

[@ColtWR]

I believe so yes

[@ufftackthegamer]

Little late on this but yes you can. If you are swapping it into an auto truck you’ll need a pedal assembly, clutch master, and most likely need to drill a couple of holes in the frame for the trans crossmember
