I had that happen to my 2019 l5p at 48000. Luckily I was still under warranty and the mechanic said the reason of failure was because the valve was made in Mexico
@@CFarmerapparently there is a travel plate on the shaft that broke loose and caused the problem. I also have the Autel 906bt that allowed me to diagnose it before I took it in to the dealer. The funny thing is while they had the passenger side tore apart, there was a recall on the block heater that they never said anything about and I just happened to run across it by running my vin a month ago. The recall expires in July this year. I never received any notification about it at all so back to the dealer it went to be fixed. Good video
Great job! Always good when you have spare part that's good. Love my Autel MaxiSys and it's saved me a number of trips to a repair shop. Thanks for the vid! :)
I really enjoy your video's. I have a 2019 duramax just like yours i bought new with 63 miles on it. I now have 210k on it. Everything that you have talked about and done videos on, I've had issues with also. Had fuel rail pressure sensor issues just under 100k. And fuel injector connectors started having around 190k. I did have my factory lift pump module fail at 75k. Other than that and the nox sensors and 2 egt sensors truck has been great. Thank you for doing these videos.
C Farmer, you need to look into the “Speed of Air” pistons. The Diesel power podcast has an interview that will blow you away! Especially if you are working on your truck things something that may really be useful to you.
I have but it's been a good while back. If I'm remembering right it was when i replaced the position 1 nox sensor. After replacing nox sensor i did a forced regen and it has stayed away. I would try a forced/ service regen
I just replace the engine on my 2017 l5p with a 2020 l5p, I programmed the new injectors to the ecm, it’s there any other engine parts that came with the new to me engine that needs to be programmed to the ecm of my truck???
I installed the one from my 2017 because the one that came with the engine since it was out of a 2020 truck, the connector was pointing the opposite side as the one on my 2017. I also have to replace a cooling line from 2017 engine that Tee’s out of the turbo and runs a cooling line into the def injector that the 2020 didn’t have. Thanks for all of your videos.
8:45 - The point of EGR isn't to "reburn" anything. Only a small portion of the exhaust flow comes back around, so EGR doesn't "clean up" the exhaust via reburning. The point is that exhaust gasses have less oxygen in them. (Combustion consumes the oxygen.) By mixing inert exhaust back into the intake stream, it displaces incoming fresh air, reducing the oxygen content available for combustion. Less oxygen means slower combustion. Slower combustion reduces peak cylinder temperatures, which reduces NOx formation. Ever since EGR was introduced it has been a tool for NOx reduction under part throttle conditions. It is especially effective on diesel, normally operating under excess oxygen conditions. Does soot and unburned exhaust content get carried back for a second round? Yes, but that isn't the point.
I’ve been watching your videos for a while. I did take a break for personal reasons, but I can’t help to think that you put all these mileage on this diesel truck and you haven’t deleted it yet. I’m sure you could toss a rock and find multiple reasons. why the pros outweigh the cons of deleting a truck so why haven’t you done it yet
With the miles i run and the states i run in, i have been checked in a Roadside inspection in Oklahoma to make sure egr and dpf were still on the truck. I feel that deleting the truck would only create more issues for me at this time. As long as the truck keeps doing what i need it to do i well leave it compliant. Almost 600k on stock dpf Filter... if i need to, i will replace it with hopes of another 600k miles. If i would have deleted the truck early on im pretty sure it would have cost double what I've spent in emissions repairs. That being said, My honest opinion is that the emissions are garbage and only installed on the vehicles to line the governments pockets.

Another great informative video. Good thing you have a spare engine other than having to spend the money on a new one.
Nice job! It's a good thing you kept that old engine for spare parts!
Thank you! Me too

i am glad you were still under warranty

Thanks C Farmer for another excellent video!
Thank you!
Great job very good idea to keep that old engine for parts

yes sir and thank you for the comment!
Nice job valuable information to know thanks
Excellent video, thank you!

thanks for video! I might be to the same on my 22 L5P
At least you got it fixed, but what a bunch of useless crap. Glad I took all of it off.

Good video bud
Great video. I suspect my 2018 gmc L5P has a egr issue. It has a deep thumping sound in the air filter chamber. Anyone else experience this sound?
Mine has a pretty agressive thump from the air box as well. it is the same after changing the actuator
Have you ever had a p20ee code on your l5p? Thanks 🙏

None that i know of. might not hurt to do a turbo actuator relearn. i didnt but probably should have

How many miles did you get on the 17 before it failed if you dont mind me asking?
501k. it still ran smooth and strong but lost oil pressure
