This truck has no blowby at all. Check this video, ua-cam.com/video/5HeO0UYBjZg/v-deo.html The problem was we couldn't bleed the the air out of the high pressure oil gallery. So you crank the engine until the injectors do it for you.
Did the injector cups on my 02 7.3 a few weeks ago. I expected to crank it a lot before it started. But it took soooo long and I was watching my ICP on the Autoenginuity sit at zero during the cranking. I was close to giving up and peeling off valve covers to find an oil leak when it finally squeezed enough air out of the rail and fired up. Runs good as new now. So anyone pulling and reinstalling injectors, relax and be prepared to crank that girl a while.
Hell yeah, I didnt get all of our cranking on video, but we were just about to cut the camera and see about bleeding air out of the fuel system. If anyones going to do this make sure your batterys are charged. It ran rough for the first 10-20 miles or so too, but then cleared up. Its been running great since.
Starter motors have about 10% duty cycle when operating under full load, meaning you can crank on it for 1 minute out of any 10 minute period. I've burned my starter out trying to get a cold blooded 7.3 to start.
it can be messy but if you pull the glow plugs out and hold a rag over the hole where the glow plug was that's a good way to prevent hydro lock. and when the injectors are removed it does take a long time of cranking to get the fuel system to get prime
It takes a long crank time to get the air compressed in the oil rails. Then they miss on 7 and 8 until the air works it's way out. Nature of the beast.
It's amazing how big these engines are my mustang was a 4.6l v8 and had decent power and these are 7.3liter engines! Beasts lol I have one and it's a big truck theses nothing it hasn't been able to do
I Just did all 8 injector cups on my 99 4x4 7.3 I had fuel floating in my degas bottle so I had at least one cracked cup. But I just did all 8 of them. I messed up and did not drain my heads first and got a lot of oil and fuel in the cylinder also!! But what I did was install my injectors back in and left my glow plugs out and harness unplugged. Then cranked it with the key to clear all the crap out the cylinders through the glow plug holes! then installed the glow plugs back in! And yea, Lots of cranking before she started and she blew white smoke for 30-40 miles before she cleared up!! No more fuel in coolant!!
+Danny Reaves We forgot to drain the cylinders of oil and had to take several hours to turn the engine over slowly by hand to push the oil out of the cylinders. Ring gaps are very small it takes a while. Of course we changed the oil after we fired it up.
Not a good idea. Using ether will destroy the ring lands on the pistons. Don't use ether on any modern diesel engine, particularly the small ones in pickup trucks, unless you like wrecking them.
You guys really should have taken the glow plugs out and blow the oil out that way, any other way is asking for trouble and you can tell that there was still oil in the cylinders when it was tough to crank at first, great way to screw your engine up real bad.
Before we tried the starter the engine was cranked over by hand for 10 complete revolutions with a 1/2" ratchet so there was no chance of a hydraulic lock . I was very aware of the issue at the time.
We also own a Chevy truck. We are equal opportunity truck owners. The only real criteria is that they are cheap to purchase and fun to modify. Check out our 84 C10 LS swap build, ua-cam.com/video/KROTR2Vyqec/v-deo.html
Yes we didn't prime the injectors as we had no way to do so. So we knew it would take a bit of cranking to start but no idea it would take so long. Knowing the starting current requirements of that diesel engine and the condition of those batteries I was very surprised that it cranked for so long. The glow plugs alone draw 200 amps.
+MrJj1620 To tell you the truth I don't know if you have to remove the valve covers. As I have said I haven't worked on an IDI engine although we are planning on getting one in the future. If you look on UA-cam you should be able to find a vid that will show you how to do it. I have always been able to find what I needed. Matt
my 92 idi 7.3 is blowing alot of white smoke on idle and even when im driving and i step on it it blows more and it smells like raw diesel can somebody help
+MrJj1620 Sounds like one of your injectors is leaking into the cylinder. I have not worked on an IDI engine before so I am no expert but I have read that new injectors are not too expensive nor hard to replace. Do a search on UA-cam for injector symptoms and replacement videos. Good luck.
When I replaced my injectors I filled the oil and fuel rails, i also has a fuel return line from the back of the heads and an oil crossover pipe but it fired right off as if i I had just turned it off and back on again
domantor11 I think that is the vacuum pump. The diesel engine doesn't produce any vacuum so there is a little electric pump mounted on the passenger side inner fender. It would normally only run for a few seconds but while working on the truck someone had accidentally knocked the vacuum hose off of the bottom of the heater. So the pump was running continuously. We figured it out when we took the truck for a drive and the heater didn't work.
1993 7.3 idi turbo clicking glow plug relay when i turn the key that is normal? Engine is hard to start in first try smoke coming under the hood. Also engine run good in idle not smoke but on the road the engine miss what is can be wrong
No the miss was caused by the fact that we didn't have a long tailed injector in #8 cylinder and the glow plugs were not working as the relay was toast. We changed the oil to Rotella T6 synthetic, changed all the glow plugs and replaced the relay. Check out our -20 degree cold start glow plug test and see the difference. It still smokes a little at first when it is that cold due to the fact that our truck is from the US and doesn't have the incoming air heater.
+THERIPPER216 If you had read the caption you would have known that we had just changed the injector cups and it always takes forever to start after that job as the high pressure oil pump takes a while to refill the injector oil galleries. If you would like to see how it really starts look at our -20 degree cold start movie and see how a real diesel starts when it is in good condition.
Cold start nou
Here is one, on another one of my videos. ua-cam.com/video/1NpDcp2s-5k/v-deo.html
LOVE THOSE FORD TRUCK'S
You won't find an arqument here👍😎
That’s why this truck has a blowby

Next time plug it in

we gave it rest stops, I did not want to change the starter😨🤷♂️

+Mike Jankoviak Thats a good tip! Thanks for that I will keep it in mind!
+Matthew Bergin (The Bergin's Garage) make sure the power is unplugged before you crank on it as well

7.3 powerstroke is a bad choice but could def go for something like a 6.9 or 7.3 idi

that looks like a very clean 7.3 engine and truck
sometimes you just gotta keep cranking'er until she fires. no other way to get'er started. glad to see you got'er going.
I've driven a couple of Ford 7.3 alittle hard on fuel but always got the job done
Our truck really likes an additive that contains cetane. Adding some seems to give about 4 or 5 additional MPG and the engine runs quieter..
now THAT was some serious cranking. MMMMMMMM. great video
Aw man look all that cheech
I can't believe my sons perfect timing on "getting the shot".
Hit it with some either
Not a good idea. Using ether will destroy the ring lands on the pistons. Don't use ether on any modern diesel engine, particularly the small ones in pickup trucks, unless you like wrecking them.
Nice just gotta get tow mirrors for that truck.
Its funny you say that, they were our first buy for the truck lol. $20 each at our local yard Kenny U-PULL!!
no, tow mirrors look so stupid
+Kenyon Payne nope lol. Love the big mirrors
Dude, what a perfect time to get under the truck.

Patrick TheBaptist Please try to keep up.
Bad idm I had the same problem before doing my injectors I replaced my idm and problem was solved try it
You need to warm up the glow plug, then turn the key off without cranking it over. I have the same one and it always works.
thanks I'll give it a try

Idk if you guys knew this or did this but the reason why she didn't start up right away may have been because you didn't prime the injectors
Yes we didn't prime the injectors as we had no way to do so. So we knew it would take a bit of cranking to start but no idea it would take so long. Knowing the starting current requirements of that diesel engine and the condition of those batteries I was very surprised that it cranked for so long. The glow plugs alone draw 200 amps.
No wonder why they put two batteries in trucks lol
If I had a Super Duty that color I would call it Big Smoke cause of the color (only og GTA fans/gamers will get the reference)
Two number 9s, a number 9 large, a number 6 with extra dip, a number 7, two number 45s, one with cheese, and a large soda.
do i have to remove the valve covers to remove the injectors sorry for asking to much is just that im new to this
+MrJj1620 To tell you the truth I don't know if you have to remove the valve covers. As I have said I haven't worked on an IDI engine although we are planning on getting one in the future.

Neah just cut holes in the valve covers LOL.
my 92 idi 7.3 is blowing alot of white smoke on idle and even when im driving and i step on it it blows more and it smells like raw diesel can somebody help

How many miles does it have
Whats thst noise when hes isnt cranking im ne wto diesels so im curious

Perfect timing on being underneath. Way too persevere haha.
1993 7.3 idi turbo clicking glow plug relay when i turn the key that is normal? Engine is hard to start in first try smoke coming under the hood. Also engine run good in idle not smoke but on the road the engine miss what is can be wrong
Yea it really worked out perfect, thanks for your comment!
This truck sounds like a broken washing machine
(Not hating)
damn that did not want to start how many miles on your truck I always liked that green still a nice color
Our truck had about 175,000 miles on it at that time.
do you work at burgins farm
+Derek sochia Derek No we don't.
actually looking at it rigth is blue
Trade u for my Rust free ex cab long bed 7.3 it's a 2000
That does not sound right
Sounds like a dead cylinder

Typical fords
+THERIPPER216 If by that you mean ``Good solid dependable trucks`` then I would have to agree.
+Matthew Bergin (The Bergin's Garage) it didn't even want to start
