Glad you gave those who are needing the visual knowledge to difficulty and the expected time that it takes to do this injector replacement job. One more big issue that I e found with these trucks is that you also may notice the abs and parking brake indicator lights come on and a DTC code be given for anti lock braking system fault detection, the simple fix to this issue is literally just an incorrect bolt used from factory that doesn’t provide the proper grounding as needed to the frame just underneath the drivers side area near where the body mounts to the chassis. Get a new bolt of better metal that will allow for better flow of grounding to the chassis and it will fully eliminate your abs/parking brake indicator staying on issue and trouble code to ever coming up again.

As a disabled ex ford dealer mechanic when I did my first set on a 2003 Duramax I was able to do the injectors, Glow plugs, fuel pump, fuel lines and water pump started on a Saturday afternoon and finished up mid day Sunday with only hand tools in my driveway. It is a job but not a hard one. Watch a lot of KZfaq videos to see how every one dose it and you will have a few options on how to handle the Issues that comes up. My only real issue was pulling the glow plugs I think they were Original (I had just purchased the truck)

Also, I’m worried it could also be that my injector pump is the culprit. The issue I’m having is my truck is filling my crank case very quickly with diesel. It pours out my over flow tubes like crazy and covers under my truck and the poor person that is driving behind me’s windshield. It’s really bad, like fills my crank case with diesel in just a couple hundred miles. I’m changing my oil about 5 times a week. And it fills up a 5 gallon bucket every time. Do you know of anyway to check the injector pump to see if it has a bad seal or something? Im guessing it would be the seal on the input shaft? It lacks a little power when towing and is hard to start only when it’s hot. And of course it has very low oil pressure once it fills up with diesel. Any help on how to check that would be great. Thank you for your time.

I bought brand new Bosch injectors for my LB7. Been sandbagging putting them in. Helpful vid. Gonna kit the turbo same time. 250k miles and 4th injector been bad about 100k. Not making oil. Just smokes when idled in traffic for too long. Injector cleaner actually helped, from massive plume to zero after a 5 minute idle. But they still smoke occasionally when stuck in traffic. % are all good and close and low. Hope I didn’t buy new injectors for nothing.

@tt7hvn 5 жыл бұрын

When I did my injectors last time, reading from the forums gave me a bunch of extra good advice. Like, putting a dab of RTV around the high pressure line that goes to the injector itself. A lot of gunk and get down there over time and I thought it was worth while. Also, given your location Rich, it probably would have been a good idea to change the lines with new ones. But, I'm assuming there was a budget to meet with this. Particularly on an LB7, more so I'd say than on other Duramax generations, fuel filtration is paramount, a lift pump is great for these trucks just for the filtration alone. Along with a CAT filter adapter, you'll have some long lasting injectors.

@stevewaclo167 4 жыл бұрын

While I agree adding sealant around the top of the injector connections will help prevent rust from forming and dropping into the injectors next go around, I’m beginning to wonder if it’s worthwhile since most times the only reason those fittings are coming off is to R&R injectors and anything that drops into the screen will need to be addressed when the cores go back for rebuilding. OK, I put silicon around mine too. 😀 Also agree on new HP lines. I notice Rich left the rail connections open during much of the job and as you noted, debris that’s not even visible can do a number on the injectors.

@devoncoolman88 5 жыл бұрын

The lb7 is a great engine. Very reliable and much simpler design then the later models. Iv’e never waited to torque down the upper rocker cover. Never had one leak yet. Also the rocker cover bolts and the injector return bolts like to strip out. Arp makes nice replacement rocker cover bolts and merchant automotive makes much better return line bolts. Merchant is an awesome source for parts and info for duramax’s.

Have you looked at the Cummins Achates opposed piston engine? According to the information, long stroke to bore ratio equates to much improved efficiency. Two cranks minimize piston speed associated with the long stoke. I remember the Nebraska Tractor Test data seemed to always favor the old John Deere two cylinder diesels for horse power hours per gallon. This is a really old engine design, the British had an OPOC engine in a ship back in the early 1900's. You can see the British engine on KZfaq videos, it is in a Museum......but today again it is new and wonderful in a pickup.....

Mechnical or VP44 lines are equal length because the injector fires once fuel pressure overcomes the spring pressure on the pintle. If the lines are not the same length, you change fill time, and timing on the engines. That is the one main difference between Mechanical and HPCR injection systems. Full authority timing control.

For $600 I’d rather be extra safe and install all 8 new lines with 8 new injectors. I still didn’t have luck even on the third set after 30,000 miles number 7 started having issues so I sold the truck. First set was replaced at 98,000 miles, second set at 140,000 miles and third set at 190,000 miles. At 220,000 miles number 7 was bad balance rate and truck was hazing bad so I was done spending money on injector issues and sold it

B&K Excavating LLC and that sucks you had issues like that with your truck. After owning and daily driving two duramax trucks for the last 13+ years (01’ lb7 , 06’ lbz) I can honestly say that it’s all about filtration and fuel additives with these trucks, if you don’t want a haze. If you want the injectors to last you must run a lubricity addictive and keep the filter changed regular with a tp3012 and watch where you fill up, many many lb7 forums topics have been started with “hazing after fill up” at a shit fuel station. I’ve fixed many hazing issues with a heavy heavy dose of power service mixed with tcw3 and a filter change afterwards.. if one can keep them clean they will last. My lb7 is on its second set with 270k miles and does not haze at idle.

@bwspyder1 5 жыл бұрын

Fantastic tutorial but pulling each injector cup and resealing the tip and new o rings is definitely cheap insurance. When wiggling the injector back and forth to get out, it can break the Loctite and you may never know that it broke loose unless it lifted. Also new hard lines are a must.

Rich, well before this video I bought an 03 LB7 with 200k on the clock and very bad injectors. I replaced them myself learning as I go, following old timer advice and torque specs carefully. I set the valves while I was there and it fired up ran great, but it had a light haze out the tailpipe. It had fresh oil and a new fuel filter. I had my new injectors tested and they were good. The oil pressure sits at 14 psi when warm, close to red. Sry for the long comment, I was hoping to get your opinion on what you think might be wrong Thanks

How much did you spend on injectors? Check your balance rates with a scanner

PLEASE HELP! Any advice on how to get stuck torsion bars out on my 1 ton sierra? Truck originally came from Canada so I figure you'd deal with the same sort of stuck. Have tried heat, sledge hammer, different penetrating fluids and air hammer. All to no avail. Any ideas appreciated! Thanks.

Just picked up a O2 LB7 with 250 K on it. Was running great, started smoking at idle and cruising speed badly, Knocks at idle a bit too. Idle won’t stay consistent and all balance rates are at zero. Command rates for one, two, three and sevenarezero arrest jump around, injectors the only thing it could be? Thanks in advance

Could a bad injector lead to low compression in a cylinder? Along with extra fuel in the crank case …it has a whole bunch of blow by all of a sudden. Thanks

i had tried Canadian diesel pro, his lb7 injectors are not bad, bosch are alot better, but they worked, i also got a reman lbz injector from him and 4 months later the electrical solenoid went bad and when i called him he used every excuse to not warranty the injector, i neveer said my truck was tuned but he tried saying that, said GM doesnt warranty the solenoid when they do, i worked there for 10 years, if anything goes bad with the injector they replace it free.

Say you have a southern truck, or western for you maybe? Something rust free. Would you then pull the cab for best access… or is this really a couple hour job for you? I find that rear bolt on the driver’s side valve cover is a real bear. I’ve done pushrods with the cab on, so I suppose I can do injectors too? Would it be of any benefit to lift the cab just a couple inches?

You can buy a special tool specifically for pulling the injectors out for like $80 on ebay. Makes it alot easier

@stevewaclo167 4 жыл бұрын

Special tool may be best, but just screw on the original HP line and twist back and forth and pull till the old injector comes out. Alternatively, there is a technique using a pry bar (search KZfaq) that is also effective.
