THANKS FOR THIS. I HAVE A 2021 L5P WITH THE EXACT SAME CONCERN. FIRST TIME IVE SEE THIS CONCERN, SO FINDING THIS VIDEO HELPS.

Wow I’ve never seen that

Great info

Most informative no-BS video I’ve seen

you explained it awesome. thank you.

I'm new to the diesel world. This video was amazing explaing that entire system appreciate you taking the time to break it all down.

Well explanation

Enjoyed your video. Great job, clear and concise in providing an overview of each components function. Thanks

Awesome demonstration and explanation for the issue. Keep up the great work!

Thanks. Excellent info.

I really like these kind of videos, new sub, thank you sir!

That's crystal clear, thanks man awesome video!

Awesome video would love to see more of these informative videos from you guys

Great job explaining the different steps.

Good thing you got all the junk off of it. I just bought a 2023 last week. I'll be deleting it very soon

Very well done explanation. Thank you!

Great video and explanation of the system. 👍🏽

Great through video

Excellent tutorial

Very informative 👍🏻

Thank you brother !!!

Love the videos! Awesome rundown on the emissions system for the L5P. I would be 100% doing a full delete and tune with most of the gear already on the table! Cheers!

Awsome video. Good information. I have an 18 L5P as soon as my extended warranty is out I'm all over this!

l5P duramax is a hot topic...lol sure is BRICKS great explanation !!!

Very clear and informative video. As a fellow KZfaqr and L5P owner, I appreciate the content. Subbed.

Great explanation! I am researching into trading in the Wrangler and getting a diesel and an 5th wheel. But great information here. SUBSCRIBED!

Great video!

Great Video! I am new to Diesel and this whole delete and why people do it and what is even in these newer Diesels. Explained the emissions system while also learning how to diagnose other problems that may arise. Truly awesome, thanks.

I have to say that,, you just saved me a lots of money and frustration. Thank you. Been looking at a diesel truck to replace my 11 years Tundra due to change in use. Given that GM and Isuzu worked together on these motors , I was pretty sure that this would be the most reliable diesel you can buy. Seen and reading on forums how many trucks have issues and for how much you have to pay for one of these trucks these days, ,,, Is completely unacceptable for these truck to crap out like this at under 500 k miles. Thank you again for opening my eyes.

New sub! So in detail and dummied it down for me to understand!😂

Your videos are a great help to un understanding my vehicle I have the Duramax 2017 Sierra Denali 3500. Your video helped out greatly with letting me know exactly what was wrong when I had sick coming into my air intake. A question was how do you clean the DPF filters manually. Thank you for your time and your videos

So many inaccuracies in your descriptions while trying to describe what is wrong will lead people who don’t know a thing about it down a bad path. You’re correct in that there are plugged exhaust components but not in the description of some of those components and there use in the system. Accuracy is key here.

Awesome video and easy to digest!!! What could he have done to prevent this from occurring? I have a 2021 L5P and want to make sure this never happens.

Force a regen every oil change and never plug up.

Just like a clogged catylitic converter on a gasser

Best explanation on how the system works.. I feel like I could fix mine .. when this happens great video definitely subscribed

Great explanation of how everything works but it would have been nice to hear exactly what kind of trouble codes or symptoms preceded this train wreck.

Love this vedoo very explainable . My Silverado 3500 hd desiel dersmax high country duelly is the first desiel I've ever owned I planned on opening a hit shot company with the truck but it's down n it sound exactly what's going on with my truck . My question is this problem covered by warermty n if not how would if cost to repair I hope it is covered

Great video of why you should get that garbage off of your truck as soon as possible.

Ty👍👍

That’s why every diesel needs deleted etc, screw the emissions ppl and DOT

Diesels,Harley Davidsons & Corvettes were meant to breathe freely & that’s it-so without saying anything thing else everyone needs to fix their free breathing capabilities 👍🏼Fresh air in & combusted gases out in a 100% free flowing manner.mic drop🎤

thats why weight loss is soo great

Well, if you had that off on my truck (not l5p owner) but a diesel owner. It wouldn’t go back on

So did this guy do a delete with out losing the weight or was he just not going into regen properly

That much soot accumulation, in a short life, was there any power adding modules installed on the truck? Something like a derringer or edge pulsar? Something is creating more soot than normal on this truck, and I’m not so sure that stock programming and power would create that much soot, that fast that it can’t regen itself on a regular basis.

Thoughts on a water methanol injection system if he is out of warranty? Before diesel power mag went out of business, they stated it made a world of difference by steam cleaning the entire system and doubling regeneration life.

I have a 2020 duramax 6.6 that did exactly what this truck did we did fix particular filter regen and it cleared all code, running good until test drive, during drive reduce power message came back would only go 65mph and made like a vacuum air sound im guessing its coming from turbo we did not pull it , did y'all just clean the turbo or replace it

Great content and how you broke it all down . This person must have been getting engine default messages right ? Why didn’t he take it in for a check up repair before he got it to this stage of it . Thanks

Shouldn't the truck throw any check engine codes when the exhaust system is clogging up? usually the computer also knows when these filters are clogging and overheats the exhaust to burn the soot before even throwing any codes. Also isn't the EGR's job to recirculate this extra soot to make sure the engine burns it so it doesn't clog the filters? Did you find anything else wrong? because just replacing the exhaust filters will only be temporary fix, the problem will come back, won't it?

THE valve not the .

Great video, one good reason some do away with these factory systems.

My air filter is always bright white and clean on the top. Usually slight darker color on the bottom foam pirce. I just replaced the dpf due to stealership recommendations after blowing turbo inlet hose and various dpf related dtc codes. Do you recommend cleaning the egr?

Another great video thanks!! Question i use my exhaust brake everywhere i go can this cause premature ware on the turbo? I do have a L5P thanks again!

Great video. How does the truck still run with a clogged dpf ? Shouldn’t limp mode be the safe guard to a clogged dpf until you can get it to a dealer ?

You should have took The opportunity to delete the egr and that thing behind the turbo.

You can clean the filter with citric acid and water.

I have had problems with my map sensor getting soot all over it since day one which was causing limp mode codes etc . The SB filters relocation helped a little bit but I still get the code from time to time . What a headache.

I just bought my first diesel truck. It's a 2019 Silverado 2500HD with 66k miles. I'm pretty excited about it. But Im very overwhelmed with all of the information I need to learn and retain. I know nothing about diesels other than basic beginner things. What would you recommend I do or read or learn to help me keep my truck from out of the shop and in good working order? What mods should I put on it? I'm not looking for power at the moment. Just longevity and reliability. So any advice you can give me would be nice! This video was very informative and helped out a lot! But now I'm worried there's a lot more parts I should look at before I drive my truck too much to make sure it doesn't break down. Thank you.

How could this have been prevented ( if possible)? Less idling and or more load on the engine to clear it out?

So how in the hell with so much back pressure it would even run ? Also didn’t any piston rings got damaged ? Oil rings? And also what was the mileage on the truck that exhaust filters got clogged ?

I have 2005 Miramax doing this , do they have the emission filter on the other side of the turbo . I was hoping it was an EYE valve causing this .

Yes brother, but show us how you changed everything

Always wondered what Blake Bortles was up to

Do they make a high flow cat yet for the l5p or will they not do that due to emissions.

how does intake side of air filter stay clean was it installed upside down????

Did the exhaust gases overpressurize the cooling system also? Considering part of the EGR system is the EGR cooler. Excessive pressure of exhaust gases in the cooling system could lead to blown head gaskets. Just curious on the overall analysis of this truck. Well done sir! Emissions is junk.

Good video, I own a 18 3500 silverado. Not sure if I missed it but how do you keep those filters after the turbo from getting plugged?

It is just so sad that they put all this crap on these great trucks and completely ruin them all this dpf egr crap. It’s a real shame

Isn’t the emissions system covered under warranty for like 7yrs or something? Anyway, I liberated my L5p at 3900 miles, I was shocked at the soot already inside at that low mileage. Cleaned what I could... don’t have to worry about anymore though!

And that’s the reason people delete that diesel headache

My 2017 just rolled up on 750,000 km and still ran like a top until about a month ago and started staying in Re Gen and wont stop showing the " keep driving" message. It kept going into limp mode especially towing my 45 foot toy hauler. After the first 2 hours in ReGen it really started pumping out the coal for 10 minutes and it went through about 7 stages of this and every time it started blowing out the coal the power got better and better then it went from feeling like a 450 HP truck to a 200 HP truck. Pulled the MAP sensor and it was solid black sludge - cleaned it and no difference. Now I have to unplug the MAF sensor to get anywhere and still goes into limp once in a while. Have to keep my reader plugged in to clear limp mode to keep going. KInda stuck because at work for another month and very limited to no shop support way up north and still have to make the 1300km drive home with this trailer when im due for days off. Its got the DEF treatment all the time, never threw codes before last month. What can I do to this thing - to either clean the entire system out or hack some shit off to keep me going until I hit civilization?

did you guys fiquire out what caused this ? open egr? not enough heat build up?? be nice to know how to cut off the problem, thanks

Great video!! How many miles did this truck have at the time of disaster?

Brand new to diesel motor just bought a 2021 2500 high country duramax. Isn’t that what the DEF is supposed to clean out when the truck regins???????

I wonder if he was running emission equipped tuning ?

Thank you EPA for ruining light duty diesels might as well just deal with 9-12 mpg and buy a gas burner my Ford 6.2 gas running trouble free 180+ k miles. They did the same to heavy duty class 8 semi truck's, ruined the reliability and fuel milage.

That's why you delete that bd

Is only the clogged piece being replaced or other parts as well?

Will the new blue def platinum help with that

And this is why you delete that SOB and stop pooping exhaust into your engine.

Will the banks exhaust system help with issue… due to it decreasing back pressure?..

Dame how much was the repair?

Hey brotha what’s the best engine oil and filter to use on these L5p engines ?

My understanding is the L5P has a regen mode/process that supposed to burn that material out?? Is that not correct?

The air filters on my L5P haven’t had a trace of soot on them before tho, is it broken?

How meny miles till this happens im at about 100k same year and truck

how many miles were o. the truck

I have a '20 Sierra 2500 Diesel Denali with 55k on the meter, bought it used couple months ago. Currently broke down with it and our RV states away from where we live. Cannot get a service appointment anywhere around us at a GMC dealer. They're telling me could be weeks to look at or fix. WTF!!! I've got extended warranty on top of factory warranty, Onstar full subscription w/Roadside Assistance and they won't tow our RV, just the truck. Anyway, the truck is running so rough the engine is shaking the entire truck. When it first started happening I was on the highway with cruise at 65mph, felt like the axle on the trailer came apart or locked up or blew a tire because the vibration became extreme. But then realized it was the engine running rough. Another thing I noticed is that the truck started going through DEF really fast. I got a message that I had 999 miles left and then 15 minutes later it said 222 miles left. Also, once I parked the truck the gauge said I had half a tank of DEF but my phone's app was giving me a low DEF alert. So I looked it over, the hose clamp on the black box on top that says "Duramax" was loose. I thought maybe it was sucking air there and that was the cause, so I tightened the clamp and took the truck for a drive without the RV. It was still doing the shaking/vibrating, so I thought maybe the DEF DPF regen was clogged up or something, so I ran the shit out of it (first time ever getting on this truck and wow is it fast for as big as it is), sooo that sort of seemed to help, but now even at idle the truck goes from running perfectly smooth for about 5 seconds to running rough and shaking the entire truck for 5 seconds and back and forth. Any ideas anyone? I have no clue about diesels, this being my first and the GMC garages are bending me over.

what is your opinion on the L5P ccv bypass system? worth the price?

Awesome video!! What were the miles on the vehicle?

Have there been problems from running a K&N airfilter?

Exactly why my 2020 doesn’t have those failure prone parts on it.

So why did the filter get stopped up and how can you clean that filter out to prevent this from happening.

Was this truck stock? No pulsar or banks?

and this is why we delete the whole EGR and DPF system - its continues to cause problems like this - very informative video

There is no way the check engine light never came on - these motors will not regen if a mil is triggered !

How many miles were on this truck

Too much idle time??

Isn't it amazing how much extra shit they put on these trucks just to make them run worse and less durable?
