I like your video just fine, but may I add that once you drain your oil from the heads and pull all the injectors go ahead and pull all the glow plugs for inspection and testing. make your injector repairs and install all the injectors but not the glow plugs. Start cranking the engine with zero compression and the starter will not overheat that much this will blow out any oil or coolant if you was dealing with a cracked injector cup. Blowing out any fluids out from the cylinder is very important, you do not want to get hydrolocked. After you see your motor oils pouring out of the injectors exhaust port, Stop and install all the glow plugs and start her up. (7.3 Lives on & on)

I purchased my 99 F250 7.3 PS new when it was introduced to the market. It has only 170K over the past 20 years because I have used it for pulling an RV or boat. Although I can work on just about any gas engined vehicle I am not knowledgeable at all when it comes to diesel engines. Thankfully there are people such as yourself who have the knowledge and know how to work on diesels and are willing to take their time and effort to make and post videos of diagnosis 0f engine problems with detailed instructions of how to do the repairs. I think your videos are exceptional in the way that you present the information in a straight forward manner that is concise, easy to follow and understand. Thank you again for your excellent videos, you do a great job making them... keep them coming!!!

Do I own a Ford or a diesel vehicle? No. Did I watch this to the end? Of course.

Remarkably great walkthrough of the procedure. Genuinely solid contribution to DIY knowledge base. Exactly what viewer needs and wants to hear. Complements on video well done Sir!

No diesel... No truck... Very little experience with injectors. Always super intrigued and learn allot by your vids. Oh, I buy every tool you recommend too. Keep it up! Lastly, Auto 101: Rule #1; never ever leave the video without letting the viewers HEAR IT RUN! 🤫

The 2 videos you did about the injector o rings has been the absolute most help! My truck is doing pretty much exactly the same thing right now. Been chasing the problem for days. Did the icp , ebp and tube. I haven't tested my hpop but ill be pulling valve cover and checking injectors.

Absolutely amazing vehicle. No info was skipped or missed. Thank you.

This is the video I needed. I had the injector harness clip break if in the injector when changing glow plugs... I was dreading pulling the injector, but thanks to the vid i know I can just pull off the electronics at the top. One day ill change the o-rings... But today isn't that day. Thanks again

great instructional video.....you reduced the intimidation factor considerably....well done....

Thanks for sharing! As a 99 F350 7.3 owner, great video. No BS, straight and to the point.

Thanks for breaking this down - great video to start learning about these motors!

Great video and I will be referring back to it when I actually perform this task. thank you

And best video I've seen on this! Thank you for being so precise!

Shoot I was just telling my wife I stumbled across at 7.3 video for idiots and it was common problem with rough starts in the morning and now my car is doing my truck's doing the same that yours did so it was the o-rings underneath after all I think I have the same problem thank you for the video sir

Great tech video !! Especially for those who cannot afford $300 an hour diesel shop

Great video...I bought my first Diesel, it's a 02 F350 4x4 7.3...I'm gonna be putting a new Garrett turbo..5 inch MBRB Exhaust..manifolds and Y pipe..and lots of other things so while I'm down that far I might as well service the injectors and replace the valve cover gaskets...thanks to you I know what it's gonna be like..doesn't look to hard.

I just installed the shims on 4 of my injectors. The armature plate on the driver side 4 had no clearance and starting was terrible until the engine was warm. Last night and this morning it cranked with no issue and ran almost like it was warmed up already. Can't wait to do the passenger side too. Just have to find my oil leak and replace the power steering pump. Good videos you make so far. The shims can be done without removing the injectors too. Just have to take your time and be careful.

Very excellent video. This is a project I've already done 4 times to r different trucks. I watched it because I'm having a different problem that you didn't discuss but I'm compelled to comment because you covered absolutely everything a beginner basically needs to know. I do a few things just a tad different but that's ok. You did an excellent job with this video, I am very impressed. Ever try working on the 7.3 on an Econoline van. No room to work.

Your garage looks more organized and cleaner than mine.

Even more fun on a van - thanks man !

Great video Thank you so much for taking your on making it we need more videos like your I just work on my but I didn't make a video is little difficult work and try to make a video at the same time Thanks again

This is excellent, very well done.

Very well done. Thanks!

What an awesome video! Thank you for sharing

Awesome video and very well spoken sir thank you very much!!!!!

Really excellent, thank you!

Great video, very informative!

Thank you Sir you read my mind with this video

Thank you very much amazing instructions

Great instructional video.

Great video and great information

Great video!!! Thanks for sharing

Yes really excellent video, thank you, God bless you

Great video. Thank you

Thats a clean valve box

You make great videos. Can you go into detail about your troubleshooting that took you from suspecting a bad icp sensor in one video to needing injector o rings in the next video.

I drove my 7.3 with nothing but diesel in the cooling system(had no water or coolant only 500 gal. of red dye in the middle of no where) and its running great with the shims I installed 4 years ago...

EXCELLENT VIDEO! GOD BLESS YOU...

Interesting. Learning new stuff all the time. Maybe i should look into doing my o rings and doing the shim check. Mine has 300k and probably original injectors. I am looking into hpop R n R for valley leaks and crossover oil line upgrade while hpop out

Very helpful thanks bud

Thank you.

Fantastic video

Great video! Now I just dread having to do it...lol

Great video bud

Thank you. Sharing.

i never comment on videos. but i had to, great informative information

Very descriptive & detailed video. Much appreciated. My 2003 Excursion 7.3 is surging immediately at startup & check engine light (P0683 glow plug module to PCM communicaction circuit). My ICP is dry & appears fine. I did replace it 3yrs ago w/an inexpensive brand so wondering if I need another. Can U explain how U determined the injectors needed new gaskets? IDK, maybe I missed a video. I'm waiting on delivery of valve cover gasket harnesses from RiffRaff currently.

Awesome….great video

Wow, I’ve been in and out of these valve covers 1 million times (mostly my fault) I learn something new every time though. I never knew about draining the oil rails. I’ve heard about it but never knew how. I always just roll the crank 1000 times. Takes forever and the truck doesn’t like it.

YIKES, what a great video!!

Nice video thanks

To remove the oil drain plugs, I recommend you use a 3/8" drive air ratchet. That is less likely to strip the hex hole in the plug.

That's a really professional work mate 👏 👌👍 you are a really fucking good 👍 👍👍 awesome working 👏👏👍 I learn a lot watching your vedeos 👏👌👍 thanks for showing your experience 👍 cheers from Norway 🇳🇴 👍

You need to evacuate the cylinders of oil and fuel before cranking or you WILL hydro lock and damage your engine! Remove all glow plugs and turn the engine over by hand a couple of times with a socket on the crankshaft, then turn it over by jumping the starter with the ignition off. Then you can reinstall the glow plugs and purge air from the system and fire it up.

i wonder if you would have issues with o-ringing the solenoid to the base to eliminate oil getting in there or is it needed for plunger movement

I plan on doing this to my obs. When I go to open the drain plug on the injection rail does it drain to my oil pan or out the top

I'm thinking I need to do this ... my truck starts in 80° as if it was below 10... once it warms all the way up it runs fine .would this be your suggestion thanks for awsome video and also shouldni drain my coolant down so whats in the motor dosnt get in my oilpan

Wish I would have done this when I changed my glow plugs..

Thanks

I drove VW diesels for 26 years. They were complicated enough, Thank you. lol This was interesting tho. Imagine all this expensive technology and parts replaces the simple Spark Plug with no moving parts. Curious if it's really worth the slightly better fuel mileage over a much simpler gasoline engine.

I thought you had to take apart the injector so you may spray tip out wear it sprays good four directions and a spring in center of injectors but I do like the video and the way you do them one by one

That’s good information I am

Best video!! I'm a big fan and owner of a 1997, turbo diesel 7.3. Quick question? I replace my injectors, not new but from another 7.3 who was running really good. I changed all o rings for new one. Now problem with my truck it smoke blue. Before I had a bit of it but was clearing after few minutes, now idle for 30 mins and still smoking blue. And if I can point another issue, truck idle great but if I floor the gas pedal it doesn't want to pass 2000rpm and smoke like crazy??? Thank you.

How did you diagnose that it was the injector orings. My truck has been surging, running rough, stalling and cranking with no start for a few months now. I can’t seem for figure out what my issue is. I have replaced the icp, IPR, CPS, glow plug relay, and the pickup foot in the fuel tank. The sensors were all motorcraft. I don’t know where to go from here. I am not getting anything but a p0603 from a snap on scanner. Thanks!

Excelent

Nicely done video. So rebuilding them is (far) less expensive than buying new or rebuilt injectors, right? Almost gives me enough courage to try it myself! Thanks for parts list! My early 99 has 317k on it and feels like it's got plenty of life left. ~15.5 mpg combined and all of the power I need so I don't think the injectors are too bad yet. But I am going to have to do something about the EBPV (exhaust back pressure valve) so I might go for the injectors while I've got it torn that far down. I will probably do the delete it but I've not found a video on that process yet. On cold mornings (less than ~35f) my truck surges and sounds like a sick jet for at least 10 minutes and I've already replaced the exhaust back pressure sensor and tube. The tube was totally rotted out so I did see some improvement. Believe or not I learn a ton from reading the comments on these videos which I why made this long comment. Hopefully I can help someone else out.

S to see the bad ORing i think my 7.3 has this issue warning light comes on going up hills shuts off going down loss of power a bit

Thanks dude awesome video

I purchased my 99 F250

you failed to put the armature plate on with the lines going side to side-or front of engine to back, this is how the magnet on the top is made to match. i got this wrong first 2 injs i rebuilt - then i senn the lines and re adjusted them.

Quick question. Did you replace the o rings with the ones from the shim guy(truckrentals)? Or did you get OEM

I'm about to pull my injectors out and get them flow tested. My rig has nearly 400,000 on her and was running strong on a recent road trip. But I know when i buzz test them a couple do sound weak so I figured since I'm going back under there and at a good benchmark why not get them tested as well. I was reading something and they said after you get them reinstalling and pull your glow plugs and try to start the engine with glow plugs out and injectors not hooked up to blow out any oil in the cylinder. Is that actually a good idea at all or sorta frowned upon?

do i have to remove the master cylinder and or the heater box to get the injectors out?

Did you leave the glow plugs out when you started it back up again? Or did you just put everything back together and started it up?

Amigo necesito ayuda mi ford 250 7.3 luego de una reparación no prende

What happend with Part 2 and 3 from the aircompressor installation video?

do you not have to evacuate the cylinders before reinstalling the injector

For a 98 Ford 7.3, that starts up puffing white, will resetting the clearances and O rings correct this?

Overall what was the estimated time it took you to replace all the rings on all the injectors

3:22 Kind of scary that Ford designed those brittle wire retainers in such a way that the tabs can snap off and get flung around by the rocker arms....

How do you know that the o-rings are leaking??

Did you take the injectors apart and replace the inside O rings?

It's been a year.. So do you still have the truck was it worth doing all that work to the injectors? Or would have been better to go on with new...

Question I have a 2002 ford f350 7.3. I just replaced the glow plugs before I put the valve cover back on I wanted to see if the injectors was working right Well the drivers side works as it should however the passager side the oil ports don't pump no oil at all does any have an idea thanks in advance.

How do you tell if the injector needs to be rebuilt or just shims and o rings?

Gotta warn everyone about hydralock so no one goes to crank there truck over and bend the connecting rods or break a piston ring pull the glow plugs all of them and crank the engine over to push all the fuel and oil out of each cylinder. If you don't do this, your weekend project will turn into a month or more pulling the engine out of the truck.

I didnt look through comments. Was your hpop tank draining oil internal?

Caint you use break cleaner to clean injector

I need to know I have stage 2 injectors will the oring kit that you recommend will they work?

Did this fix the problem

I had a shop tell me that three of my injectors have failed in the truck is misfiring really bad, is it possible to rebuild the injectors

Can someone tell me what the reason would be for shimming the solenoid when what is worn is the poppet valve!? The factory specification for the plate on the poppet valve is. 004 so if you shim it back up to that spec, and the solenoid doesn't wear to my knowledge, then why would you need to shim it? I don't believe that there would be a need to do so! Thanks..

So when you buy a "remanufactured" injector say off ebay, is this all they do? how did it run after you did this?

Need to give proper torque way on these injectors as they have 2 bolts 1 of them cant use torque.

Ok, followed your every step! And yea done! However 2 of the injectors were off? Before the .002 would not go under the thing at all. I put a .004 spacer in and checked it, one side ok, the other not. But the .002 gauge did so I just left it like that. What is your thoughts on it?

How are those o-rings holding up? Would you still recommend the same o-ring and shim kit you used?

I run one of these, and after seeing the injector, and knowing that two computers are used, and the various sensors, I think IHC made the design too complicated with too many components, and too much to go wrong. That being said, they are generally very dependable, but a simplification of the design might have been an improvement.

What is the shim and o-rings part number?

Were is the link for the shim kit?

You say quite a few times " you don't want..." give the possible damage
