Update on my injectors install-
1- These videos are amazing, and I followed everything step by step.
2- The drivers side is a bastard, but took my time. My lower gasket slipped and I had to rework, but that was my fault. Glad I found it before I was finished.
3- I opted to do my glow plugs because everything was exposed.
4- My LB7 started immediately, runs great, and I’m more confident to do more if I need to.
You are a rockstar! Keep these videos coming!
Thank you…
Thanks for the update! I am glad to hear that you found my videos to be helpful and informative. Yes the driver side is a pain because of it being so much tighter than the passenger side. That’s good that you found that your gasket slipped when you did rather than after starting it up. That is a great time to do glow plugs because you are right and they are very easily accessible. There is not a better feeling then doing a job like this and having it start up right away and no other problems! Great job and shout out to you for doing this repair yourself! Thanks and I am in the process of getting my transmission rebuild videos edited and posted. Thanks for your support on the channel!
Ordered the same injectors for my LB7 and thank you for these videos. I've watched all three and feel confident to go ahead and do the job myself. Lots of good information.
That is so awesome to hear and I am glad that the video's are going to be able to help you out! You are going to really like these injectors! If you have any questions feel free to ask and I will do my best to help you out. Thanks for watching and commenting!
Glad I found this video. I just ordered injectors from Lincoln for my LB7. Thanks for being thorough with all the specs.
That is awesome to hear and they are such a great company! You are welcome and I hope this video is helpful for when it comes time for changing your injectors. Thanks for watching and commenting! 🐝

Muy bien explicado el bideo muy interesante
Great videos thanks you for the info
Thanks! You're welcome and glad you found them informative. Thanks for witching and commenting!
In the trenches doing this job right now. This is the best "instructable" by far I have seen. Well done and thank you for taking the time to document this. Have you had any stuck injector cups? I just ordered the cup removal tool as I have at least one cup which is being difficult coming out of the bore. Also, fought the 5mm allen bolts for both the valve covers and return file line bolts. Had to use a torx to get the VC bolts out after the 5mm heads stripped and drill and easy-out the banjo bolts. Ordered upgraded hex head banjos and VC bolts from Lincoln Diesel as I don't want to have this problem again. This seems to be a common issue on the LB7. This truck spent 10 years in South Texas (Brownsville, TX) which means there is a lot of salt corrosion, could be a factor. Also, the previous owner was my Dad and he had injectors done 3 times by dealer so who know what they did or what bolts they re-used.
UPDATE: Finished the R&R of the injectors, once I had all the cups out, resealed, and new hardware kit the LB7 went back together nicely. I bled the air out with by running my FASS pump and the bleeder on filter housing and the truck came to life with a rrrappp! 40 mile drive yesterday and it seems to be running well with no hazing. Thanks again for your videos.
Hopefully this job went smooth for you. Sorry for the late reply. Thank you so much for the kind words and I am glad to hear that this video is very helpful for you. I didn't have any stuck cups but I also did not pull them to reseal them just only if they were stuck on the injector then I resealed them. The cup removal tool should be a huge help though. Those bolts can be such a pain in the you know what and you 100% did the right thing by ordering the upgraded hex bolts. Steel bolts in aluminum is just never a good thing and they will always corrode and get stuck. Dealers love to reuses any and all things that they can just to save money so its hard saying how many of the 3 times they could of been reused.
Thank you so much for the update and I am glad that it all went good for you! Hopefully the video series helped you out as well. Having a FASS makes the priming process such a breeze. One thing I would say to also keep and eye on is your oil level. Sometimes if the return banjo seals leak it will put diesel into your crankcase and (make oil) but as long and your oil level doesn't rise then you are good to go. Thanks again for your time commenting!
@@MeanBee392 Another update, truck runs great, not making oil. I made a 1200 mile r/t from San Diego to Cedar City, UT and back. Truck ran like a charm. I do have "a weeping head gasket I noticed during injector R&R but 100% unrelated to injector swap. I will be source another LB7, or pull mine out, regardless it will get new head gaskets, head studs and swapped injectors. In the meantime I did use blue devil HG sealer and it worked! No water lost over 1200 mile trip.
That's awesome to hear! That's a good trip and a great test run to see how it would do. That's kinda a bummer about the head gasket but if you can do the injector job then you can do the head gaskets as well. That is impressive about the blue devil HG sealer and good to know. Thanks for all the updates buddy!
Thanks for the video, I can use all the help I can get. I have seen a couple of other ones and I think with all of them I can get it handled. But thanks for the professionalizem.how did you clean the cups?
You are very welcome and I hope my video will be able to help you out a lot! Glad you enjoyed it and thanks for your support! I used a wire injector cup cleaning brush. 🐝
This is a fantastic video! Great job laying it out in a fun to watch well lit video. I am literally studying tons and on fb groups learning everything i can about these trucks. I will be buying one soon for my little lawn care business.
The way you worked with gloves and a clean bench with rags was very professional. Great work!
Ive heard of sac 45% over injectors. Im gonna have to go look them up now. Are they modified refurbished oem or completly custom aftermarket ones?
Thank you and I am glad to hear that you enjoyed the video! Nothing wrong with doing a lot of research. What kind of truck are you wanting to get?
Thanks! I have always been a firm believer that a clean and organized working area is one of the most important tings. This is how I have always been even being a mechanic.
You can get them new or reman. They use the injector body and are just updating the tips to the SAC style.
@@MeanBee392 Me too, I have a small portable car garage I work out of and it's driving me nuts that it's a mess. I keep my tools oragized in some of my toolbox dwawers with keizen foam. working on the rest of the drawers next. thanks for the reply. I'm hoping to get a 2500HD 2000-2004 lb7. But I'm used to the reliabilty of my 2011 Tundra. After researching I think I'll stick to a newer gas chevy/gmc 2011-2013 body style 2500hd for my lawn care business. I'de like a 3/4 ton thats reliable and can put a dump insert in. the older deisels are my favorite but I can't be fixing headgaskets and injectors unless it's a hobby truck. They just don't seam relibalbe. no offense. But I love them.
Very helpfull
Glad to hear that! I love it when my videos are helpful and informative for you guys! Thanks for watching and commenting! 🐝
Muy buen bideo puede mandarme el video cuando la prienda yo nesesito aser lo mismo com mi 2001 duramax
Excellent video!!! which injectors do you recommend for 2001 LB7?
Thank you and glad you liked it! I would 100% recommend the SAC style from Lincoln Diesel Specialties! That is what I used and they have been AWESOME! Thanks for watching and commenting! 🐝
You also need a 36mm 12 pt socket to turn the engine over to adjust the valves.
You can use that but I did not have to. If you leave the injectors out the engine will not build compression and it very easy to turn over with out that socket. Thanks for watching and commenting! 🐝
That makes sense...unfortunately I installed the injectors and then decided to adjust the valves after and it kicked my ass. Great set of videos!
O man that sucks! Then you will definitely need that socket. Thanks and glad you enjoyed them! Thanks for your support! 🐝
Hey I was wondering if you ever had any leaks on the return line torqued at 106"lb
No I never did.
Hey bro did the assembely all good but my duramax doesn't have the push type prime pump. How do I get this one primed
Glad to hear that the assembly all went smoothly. Do you have a lift pump? Sorry for the late reply.
I had a question about TDC. How do I find TDC for the rest of the cylinders?
Easiest way to find TDC it to look for "valve overlap" That it when the exhaust fully closes and right before the intake opens. Both rocker arms will be loose at this point. Hopefully that helps.
So question for you after you have replace these. I see allot of folks use reman injectors rather than buying new Bosch? What do you recommend?
I would never use a reman injector in a Duramax unless they come for a very reputable company. But for the price difference I would always go new because they are not that much more. If you are needing some injectors I HIGHLY recommend Lincoln Diesel Specialties . Thanks for watching and commenting and hopefully that was helpful! 🐝
Thanks for responding. I want new everything for this job but want to make sure I get them from a good company. Lincoln sounds good so I will contact them. I want everything that you got including the new hardware. To remove the prone to strip valve cover bolts going to try the impact hand driver to break them loose. I don't plan on reusing them but don't want to screw with them either. I like your method removing the injectors with one of the old fuel tubes which are getting replaced anyway👍 your video is the best one on CZcams.
You are welcome! That is the best way to do it IMO is to have all new parts. I am glad you liked how to use the old injector line to remove the injectors and it works really well. I would highly recommend Lincoln Diesel and hopefully this video will be helpful for you! 🐝
More Duramax Content!
Sorry I have been slacking on the Duramax content but I will get back to it soon! I have had a few people now wanting more Duramax content and the support is awesome to see and it will drive me to make more content on it. What kind of content would you like to see on the Duramax? Thanks for your support buddy!
@@MeanBee392 More install videos (turbo, cp3, headgaskets, upgrades etc), reviews, exhaust notes, all things duramax. Really enjoyed how detailed/professional the install was.
@@MeanBee392 ya man definitely a professional attitude and presentation which you gave lots of good pointers that if I would of went off truck masters video id of done it wrong so right on man much appreciated from Saskatoon SK Canada peace out bro.
What torque wrench are you using ?
I am using a Matco torque wrench in this video. 🐝
one of my high-pressure fuel lines doesn't seem to be exactly lined up, it almost feels like it's about to cross thread, but it gets on the whole way if I get it positioned right & tightens down. could this indicate i don't have the injector in the whole way, or that the injector / cup isn't seated properly? thanks
Sorry for the late reply. Did you figure out this issue? I would say it could be either the injector or the cup not seated all the way down or possibly a bent fuel line. have you torqued down the injector? I wouldn't force it because you don't wat to risk damaging the threads on the injector or fuel line. If you don't mind let me know what it ends up being.
@@MeanBee392 I literally just finished putting the driver's side back together tonight, so I haven't tested yet. I pulled the cup & injector after asking this question & redid the passenger side, and the fuel line was slightly easier to put on after I redid it, but I still had a little bit of difficulties & the line didn't line up exactly perfectly. Hoping I don't have to pull it all apart again haha
Nice and I bet you are glad you just got it back together. I think that was a good call pulling it apart again and redoing it. From what you have said about it not lining up perfectly the second time but getting it back together I would say the line is just tweaked a bit. Hopefully start up goes well for you and you don't have any problems I will keep my fingers crossed for you.
@@MeanBee392 Haha thanks - your videos were a godsend literally got me through the process so thanks for these. If the cup is unseated, how would I be able to tell? Would it be evident quickly?
You're welcome! That's so awesome to hear and I am really glad my video's were able to help you out! You you will know almost right away. It will pressurize your cooling system and start to blow coolant out your overflow. The cup is designed to seal the cooling jackets off in the head so the injector will stay cool but is never in contact with coolant. When it is running cylinder pressure will go around the cup into the head and that's how it will pressurize your cooling system. Hopefully that all makes since.
Still no startup video on the lb7 after injectors? I was thinking about getting 45 over injectors on my lb7
I am very sorry I have the video and I need to get it posted I have just been a bit busy but I shouldn't be making excuses. I absolutely love them and I will get that video up as soon as possible for you buddy! Thanks for your support and patience buddy!
I did 30 over on mine 2 years ago made a big difference however I'm going to have to do them myself now my #4 is way out of balance the guy that did them I think did a half ass job😠 so I'm going to do them some time this week to make sure they get done right this time and still stick to 30 overs...
Great video thanks for giving all the torque specs and torque sequence
@@MeanBee392 how do I prime the system
Everything was going good till I saw you torquing with a crows foot the wrong way you always put the crows foot at a 90 degree angle when torquing so you don’t over torque or under torque other than that good job explaining the process 👍
