Dude, I work on semi trucks, and with these EGR systems on all diesel engines now, its crazy how much carbon is in the intake, and some manufacturers route the crankcase ventilation into the intake and it makes a black gooey mess thats almost impossible to clean off, its ridiculous
100% AGREED! I rebuild Cats and Cummins, and the occasional Detroit and these systems are nothing but a money pit for their owners and massive headache for me
This is why we bought our last diesel one tons in '08. All gas now except for our five yard dumps/Vactor truck. Had a Navistar mechanic tell us "Drive 'em like you stole 'em"!
I wish I had done that as regular maintenance on my 6.7. It would have made it more reliable. Ended up selling it at 150k miles. Rust was starting to get to it also. Decided to switch to the 7.3 gas. It’s quite impressive and I can tell they were trying to make a gas equivalent to their diesel offering. It’s also there in many respects .
My cummins has 306k miles still all factory. Took the egr off at 260. It is a maintenance interval job. For ford i think its 70k. And same for cummins. Per warranty book. But mine was never done. So i was almost 4x over the mileage when i did it. Even still mine wasnt bad. Could still see light through it. Diyed it at home pretty easy. Purple power melts that crap.
It’s not so much if you can see light through, if too much carbon sits on the cooler. It won’t cool as effectively increasing egr and intake air temperature as well.
I have been fixing emissions engines since they came out. Maintenance is always the key. Most people don’t want to hear that. The other thing is idling is a KILLER.
In Australia, lots of people put a catch can between the crank case breather and the intake, eliminating the oil going through the intake and stopping all the exhaust particles from sticking to the intake.

One of the things Dave never points out is WHY the EGR gets this way. Too much idle time and too much fuel that can't be burned. That's why EGR was put in. There's a solution: Stop idling for hours and see if you can get better injectors. This issue went away for gas engines when companies abandoned the carburetor which wasn't efficient at mixing gas and air.
My old 4.2 ford gas v6 had the same issues. I frayed the end of a 1/2" cable chucked in a drill and ran it through all the intake ports in a parts washer. Worked amazingly.
Scary video. That is a crazy amount of soot. Makes you want to put a big bottle of diesel clean in every tank. I never knew diesels had true EGR systems. I thought only gas engines had them. The carbon buildup is awful. This is a necessary maintenance procedure. I wish every shop had this much dedication to do the cleaning and reassembly right.
Diesel additives would do nothing to help this particular problem. It's directly related to the EGR, PCV, and driving profiles. The buildup is worse on vehicles used for short trips.
@ivorscruton5121 I know they say long and hard for these vehicles, but let's be honest here this isn't a perfect world you are gonna either make a long or short trip this is just fuck you now give us money
Id love to see Dave and maybe some other youtuber do full in depth scientific emissions test on the same vehicle with an egr and then without and give us the true numbers
I'm pretty sure Gale Banks has done this. He's got the emissions down to near zero with just tuning and some other stuff(SOA pistons, intake, exhaust, etc).
@@digger105337 Dave has mentioned doing something with him. He said stay tuned several videos ago so there's gotta be something in the works. Hopefully soon we'll see it.
Truly enjoy watching your content. Great bunch of men you have there. Thanks for all the informative videos. God bless you and all your family and extended family
Anyone who puts miles on where I live (east coast Canada) deletes all this BS from day 1. Which voids your warranty but they know it’s better in the end.
😮😮Do it at home then. If you live in Comifornia or one of the other states that restrict what you do to your own property, oh well sorry about that, you should move to a free state! Ironically the government orders non-emissions equiped trucks for themselves(military) but prohibit John Q Public from doing the same. 🤔🤦🏻♂️Do as I say, not as I do!
Dave, from South Afica, I absolutely love your TH-cam channel! As a trained aircraft tech I celebrate your systems. Regarding this truck at 220 miles. Yes, things are bunged up. I think you should have mentioned that the owner must have serviced regularly for the engine to be good with only performance issues due to breathing problems. Go fot it! I love your problem analysis motto's
CCV valve to an oil catch can or 2 oil catch cans in series. And EGR pipe rerouted to tailpipe after DPF Or ECU Tune and oil catch can (s) Addition of an oil bypass filter can also help with the carbon buildup in the oil.
You guys do absolutely great work. I love watching your videos. I'm from Panama City Florida but I come to Utah once a year for 2 months because we work out at Dugway Army Proving Grounds and I just love Utah because there is so much to do and the dry weather is what I love. I just wish Utah didn't have State taxes like Florida.
While I do like both of them, I think that the four C's are way better than the four O's. I do realize that they can/do go hand-in-hand, but I'm just saying that I like your four C's better!!! Great stuff Dave and crew… Keep it up!!! 👍🏼👍🏼👍🏼
I agree with Dave that this is going to need to be considered a maintenance situation for many of the diesel trucks after about 2005 roughly. However, instead of waiting 200,000 Miles or more to do this, the reality is is it probably should be done about every 70,000 to 80,000 Miles roughly. The problem is, if you wait until about 150,000 miles or 200,000 miles, by the time you have all of that stuff inside of the engine and all the components at these higher miles, you have a lot of soot getting inside of the combustion Chambers and on the Pistons as well as in the Rings like he mentioned and the problem is with it slowly getting worse and worse with more mileage and hours, it's just going to compound to become a really big issue and if you wait until 150,000 miles or 200,000 miles to do this maintenance, you're going to have major issues as time goes on. If you are doing it more frequently, you will reduce the amount that is potentially going through the engine so you get even less and less as you are doing it more frequently so you will increase the longevity of the engine overall obviously. I'm not saying that this is necessarily something that you should have to do every 30000 Mi or 40,000 Mi because perhaps that's a little bit too frequent but if you are idling your engine a lot and you are not using it to tow and running the engine in a manner to try and get this cleaned out, then perhaps you do need to do it a little bit more frequently. But, either way, I think waiting over a hundred thousand miles might be a little bit too much. My advice would be to understand how to take these components apart yourself and do this yourself to save yourself potentially thousands of dollars in paying somebody else to do it. I'm not sure but my guess is that the reality of this is is that it's just more time involved and maybe there are just a few gaskets that would have to be replaced and so you might have less than $100 in parts to do this potentially if you were to do it yourself but if you pay somebody else to do it it's probably costing upwards of $800 or potentially $1500 or more depending on how long it takes to get all these components off and cleaned. Just get educated on how to take this stuff apart and do it yourself and save yourself a lot of money and hopefully make your engine last four or five times as long.
I have a 2021 L5P. Ever since it was new l have used the Pittsburgh Power Max Mileage fuel catalyst. It's supposed to help the soot burn off at 650° instead of 1100°. Just recently at around 20,000 miles, I installed EGR filter by FASS. I'm hoping these things help my engine live longer.
Have u notice a reduction of def after using power max ? Does it help ur motor oil maybe not as dirty? I have a 8.3 Cummins I pull a large horse trailer,with highway miles . No idling. Be great to have some feedback
I Agree, also, Regular oil and filter changes are needed more frequently because of oil contamination which is a big problem, if not done will reduce engine Life. My EGR and DPF gets stripped and cleaned every year, it just makes sense, maybe need to go further, thanks Dave.
I recommend getting a pressure washer cabinet with citrus degreaser or simple green. Especially since you're going to see a lot of these for regular maintenance. I work at the largest aerospace repair and overhaul for valves, and we use an ADF pressure washer cabinet with daraclean 235.
It’d be interesting to see one on the dyno before and after, including emission levels, NOT easy for sure, running a choked engine to max and hoping it doesn’t de-coke itself mid run. I remember the nat aspirated Transit with the bananna manifold, took a few apart to clean, sometimes just a pencil sized hole through them. There really needed to be a better way of recirculating the nitrogen etc.
Exhaust gas recirculating system is always causing problems. I learned that an efficient engine produces lots of nox. It’s produced when air get time to react at high pressure at high temperatures. In my opinion a good after treatment catalytic treatment is the best solution. If you add a heat up burner to the SCR reactor with an heat exchanger for pre warming your intake air, you would get a faster warming up time. Always remember to use an electric engine heater and let your fuel burning parking heater heat up your engine when starting. Best regards from Norway
Funny watching this after seeing Dave make a short. Then I saw his son, Miles on MonsterEngines short. Now I'm watching Dave doing a full video. The circle of content. To make people realize maintenance is important. I mean my dad was surprised when I pulled my dash apart to replace something. I was surprised he never realized topping off oil doesn't mean oil change... I'm sure he grenade his Toyota...
Prefer to breathe clean air. Dave knows how bad the winter air in his locale yet would remove diesel EGR systems if the EPA would not hit him with fines.
@@benchoflemons398 Bs if you have a proper crank case ventilation filters you don't need a catch can If you getting oil vapour carry-over EGR has already killed your rings
Hi Dave, great video on the cause of carbon buildup in diesel engine/engines due to the EGR and DPF application. Would like to see one on the same subject on cars and or trucks with a gasoline engine/engines? Keep-up the good work 😊😊😊
Great video, would love to see your shop sometime, love my 02 7.3 service every 5,000 miles,one camshaft sensor, 162,000 ,I think I'll keep it,to much to go wrong with the other engines
You could clean whole intake system without dismantling intake and egr with cooler with machine called TEXA H2 BLASTER. In Europe we are using it as regular service to prevent clogging intake system with soot, but this machine cannot clean system when its fully clogged up, it only serves for regular mainteanence every 40000 to 60000kms or 25000 to 38000miles and it really works unlike other solutions on market such as chemical or other kinds of tools.
I have a 2007 Ram 2500 with a Cummins 6.7. Mopar recommends a "EGR service" at 67,500 miles. It consists of a crankcase filter, EGR cooler cleaning and a EGR disassemble and cleaning. It's a very easy service and makes a difference in the engine performance.
It's amazing what maintenance does, All these people act like it's some unfeasible unreliable thing. And people who know how to take care of their stuff don't have any problems... Crazy
I did my 6.7 at 100k. The EGR cooler was plugged and carbon in every passage. Not a professional but was able to do in a few days. When I got tired I stopped. Truck now has a 145k and still runs great. I guess I will look at a redo at 180k. My total costs were the gasket set.
Just a heads up, Purple Magic works wonders cleaning off carbon from EGR coolers. Its not as corrosive as oven cleaner and does need a few treatments to get everything off but it does work well if the parts are submerged in a tank full of it for a day or two.
2019 with 200k miles? Holy moly that guy must've driven a cross the country and back a couple times. 2019 was only a year ago! Oh wait.... it's really been 5 years already.... sheesh time flies
I've followed your channel for a few months now and really impressed with your honesty. My question is what is the largest engine you can test in your sim-tester? Another question is what experience you have with marine engines? With your state of origin being Florida I would expect you to understand that question.
Now you have me worried. My late cousin gave me his father's 2000 Camry LE 4 cylinder. The egr valve wasn't working when my cousin gave me the Camry on May 23rd 2018. I didn't know this at the time. I've driving the Camry this way ever since. So are you saying I have damaged my 4 cylinder engine? Oh geez. I have all the things to hook up the new egr valve. But I'm worried this won't do any good. The Camry needs alot of repairs for which I'm doing. Anyways thanks much for the video.
Thanks Dave for the wonderful information I was curious if you could discuss what diesel additive is the best in your eyes snd what would you use and can you also explain why today's diesel fuel is such crap compared to yesterday's diesel thank you for all this wonderful information you supplied to us I enjoy every one of your videos and I've even liking the ones that Miles is putting on hopefully Joey can start putting videos in this well you guys have a blessed day
I had to clean out my throttle body it was full of carbon afterwards my fuel mileage went from around 15 mpg to around 20+ mpg, it does help your beast breath much better
Pittsburgh power sells a fantastic fuel conditioner which was developed by a very smart lady . It was introduced into the class 8 truck market where 12 liter and 15 liter diesels were having nightmare issues with emissions . The additive is not cheap but it only takes ounces for months usage. These are engines will go a million miles.The product have help many . It keeps dpf clean with less regens , no more inframes at 250,000 miles cause of cabon pack piston rings and plugged up egr flows sensors , boost sensors .Also troublesome down stream sensor stopped acting up The cost of live has trippled . Not every diesels owner fork out 1000.00.-2500.00 partially disassemble an engine to clean carbon.
It would be awesome of you guys could get Into putting on water methanol systems on these stock trucks. would clean it up and keep emission standards while being better for the engine: lower egts, more power, cleaner burning, etc
This happens a lot with people that buy these big diesel trucks as grocery getters and tow their little boat down a couple miles to the boat ramp, also see it a lot with ambulances or any other service vehicle with tons of idle time. If you actually use them for what they’re designed for (pulling a load), you won’t have issues. 400k on a 17 6.7 and have 150k on my 19. They pull 20k lbs every other week.
@@jellyfrosh9102 could be an unloaded highway machine. However my point is that diesels, and especially the newer ones with emissions, need to run with a load to keep everything clean. People that use these trucks to pull, regardless of brand (PowerStroke, Cummins, or Duramax) tend to not have these issues with the emissions systems clogging up
Oh I see is diesel trucks idling around. My neighbor has a landscaper who pulls up and leaves their truck running the entire time. Which means that truck probably runs 10 hours a day and only drives 150 mi. People act like it's good for their diesel truck to idle
unless you've removed the egr cooler and intake systems from your truck, you have no idea what condition they're in. They could be just as full of soot & you wouldn't know it. It has very little to do with how they're driven & more to do with the strategy the manufacturer has chose to control NoX.
@@jeffs2809 strongly disagree, it has a lot to do with how it is operated. A diesel regularly operated under load will have minimal have egr or dpf issues compared to a truck that is unloaded most of the time. Not saying that the emissions equipment aren’t a hindrance, but in my experience, if you use these new diesels how they are meant to be used, you minimize these issues.
I blocked the egr on my tata hexa 2.2 when it was 10k kilometers. engine is clean. No problems. Efficiency has reduced a bit, but it saves a lot of headache later.
Hey Dave, gasoline engines can normally operate with up to about 15% of the total flow volume through the engine, being redirected through the EGR.... Diesel engines on the other hand, they can operate with up to 50% of the total volume that's going through the engine, being redirected back into the engine through the EGR system..
My 2016 F350 DRW was that bad with only 50,000 miles, it only has 52,000 miles now. I had the intake off to put on a S&S disaster kit and was blown away by how dirty it was
Team, the upper and lower intakes for these trucks are relatively cheap, possibly compared to your hourly rates. Consider replacing them with motorcraft parts and clean the more expensive components such as the throttle. Just a thought.
Maybe exchange systems that are refurbished,cleaned out etc , then it becomes simple exchange service with someone doing the cleaning of the components! See if the manufacturers can do a mean deal on new parts to get you going ,once you have one set your good to go
I always love learning from you Dave about engines. I am curious as you start building engines with the speed of air pistons and total seal piston rings, will that also extend the life of the engine by being less regens over time? If that would help extend the life of the engine, then it should definitely be pushed by you for every build you do. Keep up the good work, love the channel
The concern is the lungs and territory systems of those around the vehicles, little kids. Organs aren't cheap or easily replaced like engines. Granted cities build huge developments right near rail yards. Check out the children of the capital city of Mongolia.
@@aaron___6014you do realize it still gos into the air correct? It just builds up reduces fuel mileage, which makes you buy more fuel to go the same distance and then your truck goes into a regen and Burns most of that out it all goes out into the environment, one way or the other They can produce diesel engines to get better few mileage and last longer and produce less emissions without the use of these devices. All they do is destroy the engine they are on.
What I’ve noticed with these diesels with egr’s is the guys who use them as work trucks ,towing heavy ,foot to the floor everywhere they go have 400k on these even non deleted..The ones that use them as day to day pavement pounders around town are losing EGRs ,turbos and fuel pumps before 100k…These things need to work!
It would be interesting to see if those "cleaning additives" would help with the buildup inside those parts, or if you are better off just physically removing them and treating them mechanically/chemically and going from there. I do agree with Dave it's way cheaper to just bring it in, do a little maintenance, than come in since you have a burnt valve, etc where you are talking $_$ to get it going!
I did this experiment and it helped only a little. However, when i spoke to a diesel expert he said strip it all every 2 years and clean the EGR valve(which is easy to get to on mine. More important is to change oil frequently 5-10k because of oil contamination. Also some engines need 1/2 tank of diesel to allow DPF Regeneration, and a regular long run to clear the loose soot into dpf..before Regeneration is effective
I was talking to a guy with a brand new Kenworth truck it was beautiful he said that it's hard to get a million miles on it this is before EGR it seems to me if you're blessed in the EGR pre-cooler clogged up and won't let exhaust gases into your engine you might get another million miles out of because the system that they created clogged up and bless you if they perfect that
I think this cleaning every 100k miles would be a fair compromise to get the life out of it you want. You have to balance the expense with the results and 100k is when it definitely needs it but not too far gone. The main reason maintenance is not done is cost so every 100k would be a more realistic interval.
just incase you didnt know but Fass has made a filter for the EGR on the fords and I know guys that clean there systems every 100,000km or 60k miles same with the DPF and SCR injector
Source the Exhaust for the EGR from after the muffler or cat if in the car. Or you might be able to use a cyclone to remove the carbon particles from the exhaust. That could dump them in to a catch container that could be cleaned on a regular basis. I is why a Dyson vacuum works so well. Yes the same Cyclone could be applied to remove carbon fines from Diesel exhaust. Yes by by DPF. Get a patent.
I understand there is two types of diesels, the older diesel runs cooler and produces carbon particles, which a DPF is used to filter out and burn off the particles. The new diesel runs hotter and produces nitrates in the exhaust, which is catalyst with the def fluid. I would be changing the thermostat's on this one, it could be running cold.
I have SWORN up and down to many trucking companies I worked for in the past. That cleaning EGR components and inspecting the sensors and valve on it should have a cleaning maintenance interval every 50,000 miles. But shop foreman's, and mechanics just brush that off. Thinking I know nothing but also Wondering why the trucks in their fleet have soo many engine problems. Larger engines like Paccar, and Cummins make it so easy to access those parts with a standard socket set and adjustable wrench.
Make a bath of ethanol, it desolves carbon. Worked really great on cleaning my particulate filter when it was plugged. Just soak it for a night or two.
The egr needs to run hot to work. My 2litr audi a3 diesel engine works very hard for me.i live in a hilly Hereford UK. I seldom get to 6th gear.I have done 254000 miles and zero problems with the sensor getting sooted up. Most people with similar engine get the coil warning sign. They just need to find a very steep hill and load the car up with a few heavy people and drive up the hill at 4000rpm afew times. The coil icon will go off on the dashboard and you wont need to waste your money on the mechanic
With the Supreme Court findings on the Chevron Deference case, we need to go after the EPA on the EGR and DPF issues they have created. The cost to the environment to manufacture and maintain these systems is more than what is prevented. The EPA has exceeded their authority to create laws and now the courts can do something about it.

@@CoachJay7212nope
😮😮Do it at home then. If you live in Comifornia or one of the other states that restrict what you do to your own property, oh well sorry about that, you should move to a free state! Ironically the government orders non-emissions equiped trucks for themselves(military) but prohibit John Q Public from doing the same. 🤔🤦🏻♂️Do as I say, not as I do!
Dave, from South Afica, I absolutely love your TH-cam channel! As a trained aircraft tech I celebrate your systems.
Regarding this truck at 220 miles. Yes, things are bunged up. I think you should have mentioned that the owner must have serviced regularly for the engine to be good with only performance issues due to breathing problems. Go fot it! I love your problem analysis motto's
I wish you guys would make longer videos! I could watch your videos for hours.
Noted!
Yessss this too!! Totally agree. Going through all the long videos binging
How much would that maintenance cost?
CCV valve to an oil catch can or 2 oil catch cans in series.
And
EGR pipe rerouted to tailpipe after DPF
Or
ECU Tune and oil catch can (s)
Addition of an oil bypass filter can also help with the carbon buildup in the oil.
You guys do absolutely great work. I love watching your videos. I'm from Panama City Florida but I come to Utah once a year for 2 months because we work out at Dugway Army Proving Grounds and I just love Utah because there is so much to do and the dry weather is what I love. I just wish Utah didn't have State taxes like Florida.
While I do like both of them, I think that the four C's are way better than the four O's. I do realize that they can/do go hand-in-hand, but I'm just saying that I like your four C's better!!! Great stuff Dave and crew… Keep it up!!! 👍🏼👍🏼👍🏼
Fair enough!
NICE!!! Thanks for the response. Love the work you guys do and love the content and the channel.
I agree with Dave that this is going to need to be considered a maintenance situation for many of the diesel trucks after about 2005 roughly.
However, instead of waiting 200,000 Miles or more to do this, the reality is is it probably should be done about every 70,000 to 80,000 Miles roughly. The problem is, if you wait until about 150,000 miles or 200,000 miles, by the time you have all of that stuff inside of the engine and all the components at these higher miles, you have a lot of soot getting inside of the combustion Chambers and on the Pistons as well as in the Rings like he mentioned and the problem is with it slowly getting worse and worse with more mileage and hours, it's just going to compound to become a really big issue and if you wait until 150,000 miles or 200,000 miles to do this maintenance, you're going to have major issues as time goes on.
If you are doing it more frequently, you will reduce the amount that is potentially going through the engine so you get even less and less as you are doing it more frequently so you will increase the longevity of the engine overall obviously.
I'm not saying that this is necessarily something that you should have to do every 30000 Mi or 40,000 Mi because perhaps that's a little bit too frequent but if you are idling your engine a lot and you are not using it to tow and running the engine in a manner to try and get this cleaned out, then perhaps you do need to do it a little bit more frequently. But, either way, I think waiting over a hundred thousand miles might be a little bit too much.
My advice would be to understand how to take these components apart yourself and do this yourself to save yourself potentially thousands of dollars in paying somebody else to do it.
I'm not sure but my guess is that the reality of this is is that it's just more time involved and maybe there are just a few gaskets that would have to be replaced and so you might have less than $100 in parts to do this potentially if you were to do it yourself but if you pay somebody else to do it it's probably costing upwards of $800 or potentially $1500 or more depending on how long it takes to get all these components off and cleaned. Just get educated on how to take this stuff apart and do it yourself and save yourself a lot of money and hopefully make your engine last four or five times as long.
You guys rock the mechanic industry…Saludos!!!!👋😃👋
I have a 2021 L5P. Ever since it was new l have used the Pittsburgh Power Max Mileage fuel catalyst. It's supposed to help the soot burn off at 650° instead of 1100°. Just recently at around 20,000 miles, I installed EGR filter by FASS. I'm hoping these things help my engine live longer.
Have u notice a reduction of def after using power max ? Does it help ur motor oil maybe not as dirty? I have a 8.3 Cummins I pull a large horse trailer,with highway miles . No idling. Be great to have some feedback
To the video editing guy, your videos look great and I love the chill beats and working scenes, keep it up!! 😁😁
Thanks! Will do!
I Agree, also, Regular oil and filter changes are needed more frequently because of oil contamination which is a big problem, if not done will reduce engine Life. My EGR and DPF gets stripped and cleaned every year, it just makes sense, maybe need to go further, thanks Dave.
I recommend getting a pressure washer cabinet with citrus degreaser or simple green. Especially since you're going to see a lot of these for regular maintenance. I work at the largest aerospace repair and overhaul for valves, and we use an ADF pressure washer cabinet with daraclean 235.
Great idea! An even better idea would be to incorporate FASS's new EGR filter solution. You should really check that out!
It’d be interesting to see one on the dyno before and after, including emission levels, NOT easy for sure, running a choked engine to max and hoping it doesn’t de-coke itself mid run.
I remember the nat aspirated Transit with the bananna manifold, took a few apart to clean, sometimes just a pencil sized hole through them.
There really needed to be a better way of recirculating the nitrogen etc.
Exhaust gas recirculating system is always causing problems. I learned that an efficient engine produces lots of nox. It’s produced when air get time to react at high pressure at high temperatures. In my opinion a good after treatment catalytic treatment is the best solution. If you add a heat up burner to the SCR reactor with an heat exchanger for pre warming your intake air, you would get a faster warming up time. Always remember to use an electric engine heater and let your fuel burning parking heater heat up your engine when starting. Best regards from Norway
My local workshop have invested in an ultrasonic cleaner specifically for cleaning all the EGR gear, comes out like new
Funny watching this after seeing Dave make a short. Then I saw his son, Miles on MonsterEngines short. Now I'm watching Dave doing a full video. The circle of content. To make people realize maintenance is important. I mean my dad was surprised when I pulled my dash apart to replace something. I was surprised he never realized topping off oil doesn't mean oil change... I'm sure he grenade his Toyota...
Hears a good idea stop recirculating exhaust gas
Better idea: maintain your shit or buy something that can be neglected. Also get a catch can, soot is not sticky without oil.
it's much easier to maintain your shit when you're not sending soot through the intake.
@benchoflemons398 even better idea- get the epa out existence.
Prefer to breathe clean air. Dave knows how bad the winter air in his locale yet would remove diesel EGR systems if the EPA would not hit him with fines.
@@benchoflemons398
Bs if you have a proper crank case ventilation filters you don't need a catch can
If you getting oil vapour carry-over EGR has already killed your rings
Hi Dave, great video on the cause of carbon buildup in diesel engine/engines due to the EGR and DPF application. Would like to see one on the same subject on cars and or trucks with a gasoline engine/engines? Keep-up the good work 😊😊😊
That was crazy amount of carbon there man waw it really did lookike a coal fire place getting cleaned dave waw! Great job once again nan!.. 👌✨👌✨👍👍👍
I used to see this and have to clean things like this all the time in my Automotive Machinists days!
Great video, would love to see your shop sometime, love my 02 7.3 service every 5,000 miles,one camshaft sensor, 162,000 ,I think I'll keep it,to much to go wrong with the other engines
You could clean whole intake system without dismantling intake and egr with cooler with machine called TEXA H2 BLASTER. In Europe we are using it as regular service to prevent clogging intake system with soot, but this machine cannot clean system when its fully clogged up, it only serves for regular mainteanence every 40000 to 60000kms or 25000 to 38000miles and it really works unlike other solutions on market such as chemical or other kinds of tools.
I have a 2007 Ram 2500 with a Cummins 6.7. Mopar recommends a "EGR service" at 67,500 miles. It consists of a crankcase filter, EGR cooler cleaning and a EGR disassemble and cleaning. It's a very easy service and makes a difference in the engine performance.
It's amazing what maintenance does, All these people act like it's some unfeasible unreliable thing. And people who know how to take care of their stuff don't have any problems... Crazy
the egr cleaning was removed when DEF was added to the Ram in '13 or '14. They use much less EGR, now thanks to DEF, to control NoX.
I did my 6.7 at 100k. The EGR cooler was plugged and carbon in every passage. Not a professional but was able to do in a few days. When I got tired I stopped. Truck now has a 145k and still runs great. I guess I will look at a redo at 180k. My total costs were the gasket set.
It's literally just a filter!
I use a power washer to clean out the intakes, works pretty good.
My solution on my truck…FASS egr filter for future and water methonal injection for existing . Truck runs best ever.
This looks like black paste and charcoal. You have done more work in 3:35 then most half way house shops. Great job Mr. Mechanic.
Just a heads up, Purple Magic works wonders cleaning off carbon from EGR coolers. Its not as corrosive as oven cleaner and does need a few treatments to get everything off but it does work well if the parts are submerged in a tank full of it for a day or two.
Great video Dave really good 👍
2019 with 200k miles? Holy moly that guy must've driven a cross the country and back a couple times. 2019 was only a year ago! Oh wait.... it's really been 5 years already.... sheesh time flies
All facts. Throttle body cleaner, EGR valve cleaner, intake cleaner. Should be apart of maintenance.
I've followed your channel for a few months now and really impressed with your honesty.
My question is what is the largest engine you can test in your sim-tester?
Another question is what experience you have with marine engines?
With your state of origin being Florida I would expect you to understand that question.
Now you have me worried. My late cousin gave me his father's 2000 Camry LE 4 cylinder. The egr valve wasn't working when my cousin gave me the Camry on May 23rd 2018. I didn't know this at the time. I've driving the Camry this way ever since. So are you saying I have damaged my 4 cylinder engine? Oh geez. I have all the things to hook up the new egr valve. But I'm worried this won't do any good. The Camry needs alot of repairs for which I'm doing. Anyways thanks much for the video.
Thanks Dave for the wonderful information I was curious if you could discuss what diesel additive is the best in your eyes snd what would you use and can you also explain why today's diesel fuel is such crap compared to yesterday's diesel thank you for all this wonderful information you supplied to us I enjoy every one of your videos and I've even liking the ones that Miles is putting on hopefully Joey can start putting videos in this well you guys have a blessed day
You may want to give disclaimer that you're not trying to promote the product because you may get lol
Great suggestion!
Miles uses Everyday Diesel Treatment and Hotshots Diesel Extreme
Oileater brand degreaser works great. Off the shelf.
I had to clean out my throttle body it was full of carbon afterwards my fuel mileage went from around 15 mpg to around 20+ mpg, it does help your beast breath much better
I've seen an aftermarket company that makes an EGR filter, would be cool to see how well they work
Pittsburgh power sells a fantastic fuel conditioner which was developed by a very smart lady . It was introduced into the class 8 truck market where 12 liter and 15 liter diesels were having nightmare issues with emissions . The additive is not cheap but it only takes ounces for months usage. These are engines will go a million miles.The product have help many . It keeps dpf clean with less regens , no more inframes at 250,000 miles cause of cabon pack piston rings and plugged up egr flows sensors , boost sensors .Also troublesome down stream sensor stopped acting up
The cost of live has trippled . Not every diesels owner fork out 1000.00.-2500.00 partially disassemble an engine to clean carbon.
It would be awesome of you guys could get Into putting on water methanol systems on these stock trucks. would clean it up and keep emission standards while being better for the engine: lower egts, more power, cleaner burning, etc
PACCAR uses a cleaning solution for EGR cleaning (called air management) that works amazing.
My gmc truck got deleted 2 weeks after i bought it in 08 16 years later and 320k miles later and still going strong
This happens a lot with people that buy these big diesel trucks as grocery getters and tow their little boat down a couple miles to the boat ramp, also see it a lot with ambulances or any other service vehicle with tons of idle time. If you actually use them for what they’re designed for (pulling a load), you won’t have issues. 400k on a 17 6.7 and have 150k on my 19. They pull 20k lbs every other week.
The guy has 220k miles on a 5 year old truck. I wouldn't say it was a high idle engine.
@@jellyfrosh9102 could be an unloaded highway machine. However my point is that diesels, and especially the newer ones with emissions, need to run with a load to keep everything clean. People that use these trucks to pull, regardless of brand (PowerStroke, Cummins, or Duramax) tend to not have these issues with the emissions systems clogging up
Oh I see is diesel trucks idling around. My neighbor has a landscaper who pulls up and leaves their truck running the entire time. Which means that truck probably runs 10 hours a day and only drives 150 mi. People act like it's good for their diesel truck to idle
unless you've removed the egr cooler and intake systems from your truck, you have no idea what condition they're in. They could be just as full of soot & you wouldn't know it. It has very little to do with how they're driven & more to do with the strategy the manufacturer has chose to control NoX.
@@jeffs2809 strongly disagree, it has a lot to do with how it is operated. A diesel regularly operated under load will have minimal have egr or dpf issues compared to a truck that is unloaded most of the time. Not saying that the emissions equipment aren’t a hindrance, but in my experience, if you use these new diesels how they are meant to be used, you minimize these issues.
I blocked the egr on my tata hexa 2.2 when it was 10k kilometers. engine is clean. No problems. Efficiency has reduced a bit, but it saves a lot of headache later.
Hey Dave, gasoline engines can normally operate with up to about 15% of the total flow volume through the engine, being redirected through the EGR....
Diesel engines on the other hand, they can operate with up to 50% of the total volume that's going through the engine, being redirected back into the engine through the EGR system..
My 2016 F350 DRW was that bad with only 50,000 miles, it only has 52,000 miles now. I had the intake off to put on a S&S disaster kit and was blown away by how dirty it was
Team, the upper and lower intakes for these trucks are relatively cheap, possibly compared to your hourly rates. Consider replacing them with motorcraft parts and clean the more expensive components such as the throttle. Just a thought.
disband 3 letter federal agencies.
It’s getting closer to that point.
I got an early 99 7.3 with 430k miles still running the day it needs to be opened up id like yall to open it and do a video review about it 😂
So very thankful I live in a place where I don't have to leave this crap on my truck. Informative video though thank you.
Oven cleaner... yes, I love it too... I buy the cheap stuff from Dollar General... I just need to post some of my videos
Maybe exchange systems that are refurbished,cleaned out etc , then it becomes simple exchange service with someone doing the cleaning of the components!
See if the manufacturers can do a mean deal on new parts to get you going ,once you have one set your good to go
I always love learning from you Dave about engines. I am curious as you start building engines with the speed of air pistons and total seal piston rings, will that also extend the life of the engine by being less regens over time? If that would help extend the life of the engine, then it should definitely be pushed by you for every build you do. Keep up the good work, love the channel
The EPA at its finest. I'm sure the chemicals to clean the system's out and the energy spent making new motors really saves the environment
It’s not about energy it’s about particulates and smog
@@joemclaughlin8657 and what is a byproduct of creating the energy needed to maintain these systems.......wait for it.......
The concern is the lungs and territory systems of those around the vehicles, little kids. Organs aren't cheap or easily replaced like engines. Granted cities build huge developments right near rail yards.
Check out the children of the capital city of Mongolia.
@@NotBackstretch not particulates and smog if that’s what you’re asking. How do you think we make energy?
@@aaron___6014you do realize it still gos into the air correct? It just builds up reduces fuel mileage, which makes you buy more fuel to go the same distance and then your truck goes into a regen and Burns most of that out it all goes out into the environment, one way or the other They can produce diesel engines to get better few mileage and last longer and produce less emissions without the use of these devices. All they do is destroy the engine they are on.
What I’ve noticed with these diesels with egr’s is the guys who use them as work trucks ,towing heavy ,foot to the floor everywhere they go have 400k on these even non deleted..The ones that use them as day to day pavement pounders around town are losing EGRs ,turbos and fuel pumps before 100k…These things need to work!
It would be interesting to see if those "cleaning additives" would help with the buildup inside those parts, or if you are better off just physically removing them and treating them mechanically/chemically and going from there. I do agree with Dave it's way cheaper to just bring it in, do a little maintenance, than come in since you have a burnt valve, etc where you are talking $_$ to get it going!
I did this experiment and it helped only a little. However, when i spoke to a diesel expert he said strip it all every 2 years and clean the EGR valve(which is easy to get to on mine. More important is to change oil frequently 5-10k because of oil contamination. Also some engines need 1/2 tank of diesel to allow DPF Regeneration, and a regular long run to clear the loose soot into dpf..before Regeneration is effective
Curious if you could get together with FASS egr filter guys and look into whether or not those new egr filters are worth it.
good idea Dave, but what about designing a high pressure percolator filter for the soot
I was talking to a guy with a brand new Kenworth truck it was beautiful he said that it's hard to get a million miles on it this is before EGR it seems to me if you're blessed in the EGR pre-cooler clogged up and won't let exhaust gases into your engine you might get another million miles out of because the system that they created clogged up and bless you if they perfect that
I think this cleaning every 100k miles would be a fair compromise to get the life out of it you want. You have to balance the expense with the results and 100k is when it definitely needs it but not too far gone. The main reason maintenance is not done is cost so every 100k would be a more realistic interval.
Hey dave, where is the video of a full rebuild of on the for 7.3 powerstroke? Love the powerstroke videos, thanks
just incase you didnt know but Fass has made a filter for the EGR on the fords and I know guys that clean there systems every 100,000km or 60k miles same with the DPF and SCR injector
My 15 LML Duramax has 198k on it and now I’m thinking this needs done for sure
Great job! Very informative
Glad it was helpful!
Ultrasonic tank makes these like new. I do it every build
Source the Exhaust for the EGR from after the muffler or cat if in the car. Or you might be able to use a cyclone to remove the carbon particles from the exhaust. That could dump them in to a catch container that could be cleaned on a regular basis. I is why a Dyson vacuum works so well. Yes the same Cyclone could be applied to remove carbon fines from Diesel exhaust. Yes by by DPF. Get a patent.
Love your videos, Thanks!
All that Back Pressure Chuffing up Everything Keep up all Filter Changes , oil Never take your foot off the Pedal !.
I understand there is two types of diesels, the older diesel runs cooler and produces carbon particles, which a DPF is used to filter out and burn off the particles. The new diesel runs hotter and produces nitrates in the exhaust, which is catalyst with the def fluid. I would be changing the thermostat's on this one, it could be running cold.
Thanks Dave!
I have SWORN up and down to many trucking companies I worked for in the past.
That cleaning EGR components and inspecting the sensors and valve on it should have a cleaning maintenance interval every 50,000 miles.
But shop foreman's, and mechanics just brush that off. Thinking I know nothing but also Wondering why the trucks in their fleet have soo many engine problems.
Larger engines like Paccar, and Cummins make it so easy to access those parts with a standard socket set and adjustable wrench.
Make a bath of ethanol, it desolves carbon. Worked really great on cleaning my particulate filter when it was plugged. Just soak it for a night or two.
The egr needs to run hot to work.
My 2litr audi a3 diesel engine works very hard for me.i live in a hilly Hereford UK. I seldom get to 6th gear.I have done 254000 miles and zero problems with the sensor getting sooted up.
Most people with similar engine get the coil warning sign.
They just need to find a very steep hill and load the car up with a few heavy people and drive up the hill at 4000rpm afew times.
The coil icon will go off on the dashboard and you wont need to waste your money on the mechanic
DAC fir the win ,if you can doucument enough to get a clear fix ,you win ,😎
