I have a lly with 345,000 on factory injectors. Last year when I had the injectors out for head gaskets, the injectors were on the edge of needing replaced I just didn't have the funds to do so. Well they r to the point of hazing at idle and balance rates are getting pretty bad. I ran across a kit that includes nozzles, pintles, o - rings, the ball and seats as well as the crush washers for about $500. I have seen people rebuild lb7 injectors, just not lly and was wondering how big of difference there would be and if anyone has done this?
Injector rebuilding

What these guys said^^^^^^^
I've seen nothing but headaches from the "home rebuilt injectors".
As a matter of fact I've seen more then one engine destroyed from a stuck injector after a "money saving" "self injector rebuild".
If you don't have the money to fix it right the first time, you definitely don't have the money to do it a second time......

Problem is that I can't afford them. When I had to do the head gaskets I had to replace a piston due to a glow plug tip had broken and cracked the top of the piston. I had to refinance the truck to afford that. Plus the 2 kids usually take most of the money
well since they are not all they way out id suggest just try and save up money and replace them when the need it.
Post up the balance rates

From the sounds of it you don't have the money to replace with new ones. I will say that when you spend $500 on this "rebuild" chances are you won't have the money to fix it when the band aid fails and wipes out the rest of your fuel system, or worse the money you just invested into the trucks motor. These injectors use precision machined pieces and need to be tolerance checked to make sure they are within spec. You also won't be bench testing them to make sure they flow properly either. There is more to it than nozzles, pintle springs, check balls and washers.
Believe me, some of know from experience and learned the hard way.:thumb:Start saving and reaching out to Brent from Lincoln Diesel, he is a good man.

I read a post on here a while back and it had to be some of the best damn advice I've seen on this forum to date.
If you own a diesel put money aside every week in a separate account because it's not if but when the injectors fail.

You have 2 options.
One, save up the $2000 or so to buy good quality injectors and do it yourself.
Or spend $500 now, and then a minimum of $2000 shortly after to buy good injectors.
So, $2000 now and it's reliable and you do it once. Or $2500, have to do it twice, hope you don't destroy your engine in the meantime.
I don't mean to be a dick but you WILL NOT be successful rebuilding your own injectors!!!
So tell me how it is your saving money again?

I'm with Awenta, they ALL fail, not just LB7's. And I don't think LB7's are the worst anymore either. SEVERAL who do these for a living(I used to, not anymore) have said LLY's now hold the title. Do a search on P0087, most of those on stock trucks are bad injectors, yet many just keep running them putting on lift pumps, 2nd cp3, extra coolers, shimming the rail valve, and so on, but the true problem is injectors with high return rates. But when you tell them its injectors, they say only LB7's have injector problems.
I'm not trying to start any shit but I'm trying to save money and also wanting to understand why they fail. I know all go bad at one point or another I have operated enough class 8 trucks to know that even new rigs can have bad parts. I asked this question to see if it can be done and correctly by me and not have to pay out the ass to get injectors. If the injectors can be re manufactured then what process and parts do they use and can we get them. It's like this big atomic secret to rebuilding injectors, why. I did not pose this question to be told if you can't afford it then don't get that kind of vehicle. I'm not against spending money but would like to save it when I can. I have seen people do this but it haven't been able to find out if the rebuild worked or not. I may not be able to afford new ones right now but there is a rainy day fund set aside for costly repairs. People say u can't rebuild a automatic transmissions either but I have successfully rebuilt 4 Transmissions in the past for family members in the past with them being on the road for years with no issue. If I don't have the equipment necessary I don't mess with things but I'm not against trying...
You don't have the equipment necessary to rebuild your injectors. That's what these guys are trying to get you to understand. There is more to it than throwing a few parts in there. You need the proper equipment and knowledge to do it right or you will end up costing yourself way more than a set of injectors. Save yourself the time and headache and just buy some quality injectors.
They are just saying that it's not a good idea. People come on here and ask questions and get answers they don't want to hear and do it their way anyways then next thing you know it's messed up worse then what it was. Just trying to save you from a costly mistake.
You don't have the equipment necessary to rebuild injectors. Especially not common rail injectors.
Automatic transmissions are a walk in the park compared to a common rail injector.
Lots of people have the same attitude as you. Since I've never attempted it myself I can't say exactly why they fail. But I can tell you I've tried advising a bunch of people not to try it themselves. Those that ignored me ended up regretting it. Not one single person that I know of has been successful. They always end up dumping the truck because it ran like shit afterwards, or buying good injectors in the end. Or like I said earlier, stuck an injector and trashed an engine.
Your not starting shit. But if you don't listen to those of us who know better you will be left with a big pile of it......

Thank u for the answer, and yes u did give me answers that I wanted to hear. Until now I haven't heard if the rebuilds worked or not, so thank you. Usually no body says anything about it. With that said I'm going to ask another question. With my commercial discounts I can get a set of BWD remans for close to wholesale pricing. I haven't heard much except what was said earlier, good quality injectors. Has anyone had experience with them?
