I wanna do an egr delete on my truck it’s a 91 k1500 5.7 tbi but the only thing that is stopping me is the talk of engine knock and higher exhaust temps and obviously I don’t want that just a little more context my truck is straight piped I have no clue if that matters or what but what should I do I need your opinions
There is an option that you can do if you are worried about engine knocking. You can put a plank but with a small hole in the middle of the plank. You can adjust the hole size depending on your preference.
This is WITHOUT A DOUBT THE BEST EXPLANATION about the EGR! All the other videos ive seen only focus on the egr recirculating exhaust gas into the intake, but they never explain why, what for, the way it all operates. This video COVERS IT ALL! I could honestly say that i was one of those who considered the egr a dumb idea and question what it was for. THANK YOU FOR THE VERY INFORMATIVE VIDEO!
@skata skatata as if getting an EV makes less pollution and reduces carbon footprint. *cough cough toxic lithium pools & cobalt mining* Fuck your EVs. Hydrogen-powered ICE is the future of clean combustion.
mechanic here , this guy is correct, also D4D hilux/prado etc pistons crack due to high engine load (full power up a hill towing a caravan example), hot piston ,cold fuel shot at piston.......so if you can lower the combustion temp you improve the chances of pistons lasting. so EGR needs to stay. sadly it will soot up the intake but there are ways to mitigate this. im sure ill get critics but its true (i wish it wasnt haha)
I have been a heavy duty diesel mechanic for over 30 years now. None of the emissions changes they have made have given trucks better fuel economy. But like he mentioned deleting the egr system greatly effects the combustion temperature. I have seen many deleted engines and they are know for cracking the head due to higher temperatures.
Hi sir, I own a BMW E46 320d 150hp. I deleted the egr without problems after it. It's an euro 3 car. Do you think I could have those head problems on the future on It ?
@@Adrian-re9fh From the research I just did on your BMW it looks like they are using the same head casting before and Afters they added EGR to that engine. So as a everyday driver not trying to be a high profor
Ive watched at least 10 videos on EGR and NOTHING has explained it with so much clarity as you have. I feel I fully understand it and other things now regarding engines, such as pumping loss which I have never heard before today. Subscribed INSTANTLY 🏆
You should be a teacher if you are not already.absolutely brilliant video explaining everything including pros and cons.even if 1 person benefits and is educated your work sir is a triumph.education is empowerment and you have empowered already 60k plus people.bravo may you keep helping people and get your just rewards.
Woah ,if you don't understand will never understand. What a top notch explanation and details. Superb. Very smooth and a calmly way no background music ,I really enjoyed and learned from it.Thank you for your precious time and effort. 😊
I'm not a mechanic, and I have no wish to get dirty, but I'm here to educate myself about the EGR on my BMW X5 XDrive, which triggered my engine management indicator twice, then self cleared. My mechanic confirmed via diagnostics that it is egr. Now then, your explanation and detail delivery is top notch. You make me want to come out of electrical engineering retirement to be a mechanic. Well done sir.👍🏿👍🏿
I doubt anybody could be bored with such a well presented and comprehensive explanation of the workings of the EGR valve, up until now I had no idea it was so complex and desirable. Thank you for this video I'm subscribed and about to further educate myself with your help
Very well explained about the egr system 👍 I have a 1KD-FTV 3L turbo diesel and what I did after removing and cleaning the whole intake system was put a blanking plate with a 7mm hole in between the egr cooler and number 1 pistion intake . This still allows the egr to flow at a lower rate sloweing down carbon biuld up with no codes coming up 😊 worked 4 me .
Brother...that was so to the point..and informative...I watch Chris fix, Scotty , a handful of other vehicle diagnostics and repair channels..dude that was delivered in a manner that I have to say is one of the easiest to get a good mental grasp of the egr system..the illustrations the slow pace.. the constant explanation of everything mentioned previously. ..dude you got a like and subscribe today...id rank this video up there with a few of my favs from project farm...so yeah. Um guess I'm about to binge watch the rest of your videos until the Dallas cowboys game comes on. Thanks boss
Literally this guy answered questions as my mind was thinking them up! I'm same as you as in chris fix, scotty and everyother tom dick and harry. I have not had such the pleasure as watching this guys videos, explaining every detail we actually require! Spent hours searching on youtube and google and forums and to finally get somewhere!
A friend of mine removed the EGR on his Mercedes Sprinter and got 20 - 30% lower fuel consumption, with todays prices on Diesel this is a HUGE saving....
Outstanding. No one else has explained the EGR as an entire system, and most importantly that there are real benefits to its design, like pumping losses and combustion chamber temp. It settles it for me, I will not blank mine but will simply clean or replace it when needed, and this will prevent me from confusing the ECU. Cool speech accent too.
WONDERFUL EXPLANATION!! We know that people know what they’re talking about, when someone who doesn’t understand a thing about these topics, finds it easy to understand.
Absolutely excellant coverage of the EGR system, your methodical and measured approach to teaching your subject is phenomenal! Thank-you, well worth the time spent!
Yes! Thank you for mentioning pumping losses in relationship to the EGR. Clear explanation and demonstration, excellent! Well done. Love the little throttle moving from underneath the sheet of paper, nice🙂
@@MrDIYer explanation and illustration was very good and informational, oh and who ever got bored did not want to learn something new, god bless you keep the good work.
@@MrDIYer If the egr is deleted on a diesel, doesn’t the intake valve being open during intake prevent pumping loss? If not open wide enough, it could be tuned to open more, allowing the piston to move as intended? What about the excessive heat? Is there a software/tuning solution or hardware (cooling) solution besides obviously an egr?
16:53 carbon buildup is EXACTLY why I deleted the EGR....Owned 4JX1 car since 2000, now 35000km's...deleted EGR 3-5 years ago...Excess black smoke STOPPED during acceleration...Performance SAME....Economy SAME...Oil is CLEANER now at changes....Needles to say what I think about EGR :)
Probably it was faulty already. EGR cycle only happens at low rmp without power demand. If you floor it, EGR just disengages. Probably your egr was stuck open and your engine did not get enough oxy during hard acceleration, it was the root cause of the black smoke. Nevertheless I deleted mine as well... TDI has lot of kms, slight amount of oil coming from my turbo and pcv valve too. If it mixed with diesel exhaust gas, it just makes huge mess. I don't give a shit about a small amount of inefficiency or greenhouse gases, if I do not have to disassemble the whole intake system and clean it with harsh chemicals every 100k kms.
@@wolforla My 2000 now has nearly 370km and continues to run fine with egr disconnected. My only problem is 1 litre of diesel gets into the sump every 1000km due to injector issues, NOT sleeve or seals since they have been done twice recently. I have purchased an injector spring and o-ring overhaul kit but requires actual dismantle of injectors to fit, do-able and not too hard but simply cant be bothered.' Instead I simply change oil every 2000km and low refill with just 5 liters of any cheap 20w50. Yes, car starts and runs fine even in winter with thick oil. Drain when dipstick shows overfull and then fill with 5l which brings it to just below ADD LINE on dip stick. Good thing is that diesel in oil plus regular changes (every 2k) is cleaning crankcase - been doing it nearly 18 months now - 20k
I had an old Eagle Talon with an EGR delete. Other than the PCV garbage the intake was clean. I did get quite a bit of part-throttle knock on hot days at low speeds, but highway gas mileage in the USA was about 31-33 MPG depending on ethanol content at a steady 70-75 MPH.
@@wolforla Mine was throwing out too much black smoke DURING hard acceleration now no longer does since blocking vac line to EGR valve. EGR valve is still fitted but no longer opens :)
This is a great video. I had it explained to me that the EGR cooler was responsible for cooling the exhaust down to less than ambient, which I thought didn't make sense. This explains how the EGR reduces temperature much better
I wasn't even looking for EGR Info but decided to give this a watch based on the rave reviews.. I am now so much richer for having watched this, thanks! One day I might clean my EGR valve.. maybe..
By far the best videos to learn why things are designed this way and how it properly works, watched a few videos of yours. Very thoroughly explained. Funny that after I was set to do several modifications, all recommended by shops and 100s of videos on you tube why its good to do, come here and all is overturned!
Awesome video and a huge thank you. I was about to blank off my EGR system and bypass the cooler on my 3.2Lt Ford Ranger due to an issue this vehicle has with the EGR cooler failing and hydraulic locking the engine due to coolant entering the intake. Now I think the best approach is to install a new EGR cooler instead.
I cracked the head on my ranger 3 months after deleting egr. Mechanic I took it to said he sees it all the time when egr is deleted due to higher combustion temps and so forth. Doing research I found this video, probably best not to delete it.
@@NoOne56488 ohh that's why it takes forever to warm up compared to petrol? Cuz it's hotter? And Like at 0 degrees it has to do high idle in order to stay at operating temperature? Can't speak for cylinder temperature but I saw reduction in egt after turbo. After egr delete. And after straight pipe temperature reduction was even greater. Hey if you love all that sand(carbon) in our oil by all means leave it all in place! More power to you!
This is almost word for word how I was taught this system by a master mechanic who was my teacher at North Oakland Technical Training Collage. If you are not a teacher you should consider doing so, thank you for your insight and I will subscribe! As a licensed mechanic, I cannot legally delete any OEM system or change the system in any way. I use a Catch Can on my direct port injection Cadillac BUT I will not install one on a customer vehicle out of an abundance of caution.
bored ? you joking right ? this is the best video i've seen man you made me happy and very wanting to learn more and more about mechanics i wish but the best for you man you are a legend
Nice explanation, I've been driving diesel cars for taxi for years. my advice, if you don't want endless costs, issues and codes, get a diesel car with less sensors, egr, dpf, adblue, additives and other complicated components that needs the car to be plugged in to figure out what is going wrong. diesel cars only needs service and that's it.
hopefully you can still buy completely analog diesel engine that can pass modern emissions requirements. Especially Euro V/VI requirements. Nowadays you can't do that anymore without aftermarket exhaust treatment systems.
Absolutely fantastic! So clear and unhurried and captivatingly well explained. Best “How it works” video I’ve ever seen. Thanks so much for taking the time to put this together. Huge thumbs up! Regards Guy
That explains exactly what was happening to my Ford Transit. Started knocking noice and low power after not a great amount of miles. Still a young motor. Still went but slow build up to 100kilometers. Had i seen this awesome video earlier. I would have cleaned the EGR. I literally wrecked the entire vehcle because of it and sold it as parts.
First, brilliant explanation of the EGR system, purpose & functionality! Literally the best I’ve seen. I have a 2022 ecodiesel 1500 Ram in the US. A narrow Q re the portion of video explaining potential power loss and efficiency loss from excess fuel being used in combustion due to lower combustion temps that would result from egr delete (esp on diesels), IF that is the only modification done & the OEM ECU parameters & programming remain the same. So If I understand correctly, this would apply ONLY if the ECU remains programmed & tuned to OEM parameters and thus the ECU still ‘thinks’ there is a fully operational EGR system in place & functioning as it did straight from the factory. HOWEVER, almost all EGR deletes on modern diesels also include a tuning or remapping of the ECU to deal with that issue; so with BOTH a) EGR delete and b) ECU tune, that issue is resolved, correct? doing BOTH should actually result in more oxygen for combustion, thus higher combustion temps and thus both some INCREASE in BOTH 1) power output (HP & TQ) AND 2) better efficiency (MPGs), correct?
Thanks sir planning to delete my egr....luckily i saw ur video....and i understand the purpose of egr ...ur voice sounds like my teacher on college...he is a marine engr officer....
That was so well explained I've decided not to do an EGR delete on my Amarok. I've had the carbon build up twice in 160,000 klms and now know that it won't be a problem if I drive it like I stole it from now on.
Very good explanation. Very informative. Problem is that only 1% of vehicle manufacturers train their workshops on the cleaning of the EGR systems and intake. Second problem is it adds to the maintenance costs for the owner. A manifold full of carbon will have huge power losses. I dribe a 3.2 Diesel and cleaned my manifold afyer 75000km the amount of carbon in the inlet manifold was scary. To remove and clean everything tool about 4 hours. Labor rates is the most expensive part of services can you immagine how much it will cost a owner to have this work done every 75000km When the EGR cooler fails and it will it will add huge cost to the repair bill.
The exhaust gas going into the engine (or your torch in your experiment) is reducing complete combustion of your diesel and in your torch the butane. That is why it lowers EGTs. I would just use an uprated FMIC to lower intake charge temperatures, the colder/denser air going into the cylinder, will cool the cylinders more, the ensuing EGT will be lower. I recommend you remove EGR from your ECU map - remap. I took off my intake manifold after 80K miles and it was covered in an oily carbon sludge reducing the intake volume. Fortunately it was not hard and could be removed easily without the need for walnut blasting. The oil carbon sludge leads to compromising the intake butterfly flaps which can then break off and go into the cylinder and scrapping the engine and turbo; not worth the risk...
Brilliant video - what you failed to mention is that EGR is also used to control combustion overtemp. Diesels EGT runs away under heavy loads - resulting in cracked pistons and cylinder heads. EGR opens to protect the engine from overheating.
i was planning to delete my EGR. Thank you so much i stumble on your video. ang galing po ng pagkaka explain nyo.... kaya napa subscribe agad ako sa inyo.
I recently deleted my EGR but after watching this I am considering refitting it. I must admit I didn’t really see any improvement in power after removing and blanking it. I’ll keep an eye on engine temp now too. Thanks again. Guy
@@jarethbower9665 if I’m really honest, I have noticed no difference. I have an MOT coming up on the 3rd Feb so let’s see if it passes emissions, if not then the EGR is going back. That said, I have also recently replaced the air filter with a good after market one which DID make a difference, now whether the delete works in sympathy with that is a question that may be answered if I switch back plus, when I fit my Vortex exhaust which will move more air, that may also benefit from the EGR delete and may offset the emissions issue… if there is one. So all a bit up in the air but as of yet, no difference.
So to follow up. I just had my Discovery 2 go through it’s MOT and it passed with flying colours including emissions despite the EGR valve delete. So it would seem it doesn’t do much. I haven’t noticed any increase in engine temperature or any other negatives. I would say there is a very slight improvement in the turbo lag but that might also be due to the performance air filter which I fitted about the same time. Regards to all Guy
Brilliantly explained with a clear language! Looking forward to watch more! But when I watch my engine with a OBD-App, I can see, that the EGR is also working in cold engine during idling. No faults in ECU. Greeting from Germany!
I apprichiate your videos and hope you keep making them for the rest of us to grasp a better understanding. Could I ask what would cause a gasoline and diesel engine to go into high revs or be stuck in high revs? My friends engine is doing this and he said he has tried everytging he can think of...
Everyday we should learn something new, today I did. I learnt that the engine/air shut off is not just to prevent runaway in a diesel engine. With servo motor control, more can be done. My question is though, could older systems with vacuum control modulate the valve/s openings accurately ? Great video, very informative 🙏
Deserve mo Sir ng maraming views... One in a million vlog ito congratulations 👏🥳 keep watching and support especially Ads from Al Khafji Saudi Arabia 🙏
Problem with that solution is that you can’t find anyone to do a tune for you anymore. They’re all afraid of getting caught. Also, his video assumes the optimal running conditions in either EGR or deleted setup. A tune just turns off the EGR computing so as to allow the engine to run “normally” again without it. This doesn’t change the pros and cons.
thank you for that video, honestly, it's the best explanation about the EGR on the TH-cam. your explanation is very precise, I found in this video the information I search for several years.
are you Filipino sir? this is the best explanation about EGR, I own a nv350 & someone suggested me to condemned the EGR , I just laugh coz he doesn't own a car.
I was looking for this video a few weeks ago cleaning my egr passages on my 4cylinder honda 2.4 i had the intake off intake plate egr egr passage/water outlet off i was getting im there like swimwear but i couldn’t figure where it was sourced from i eventually decided cylinder number 4 has a passage without confirmation i was right im glad to see

I've been driving diesel cars for taxi for years. my advice, if you don't want endless costs, issues and codes, get a diesel car with less sensors, egr, dpf, adblue, additives and other complicated components that needs the car to be plugged in to figure out what is going wrong.
diesel cars only needs service and that's it.
hopefully you can still buy completely analog diesel engine that can pass modern emissions requirements. Especially Euro V/VI requirements. Nowadays you can't do that anymore without aftermarket exhaust treatment systems.
Best explanation video about EGR I have ever seen on Internet !
Absolutely fantastic! So clear and unhurried and captivatingly well explained.
Best “How it works” video I’ve ever seen. Thanks so much for taking the time to put this together. Huge thumbs up!
Regards
Guy
Genius ito na paraan para ma double ang gas consumption at madaling masira ang makina. Good business sa mga manufacturer 😅
That explains exactly what was happening to my Ford Transit. Started knocking noice and low power after not a great amount of miles. Still a young motor. Still went but slow build up to 100kilometers. Had i seen this awesome video earlier. I would have cleaned the EGR. I literally wrecked the entire vehcle because of it and sold it as parts.
First, brilliant explanation of the EGR system, purpose & functionality! Literally the best I’ve seen. I have a 2022 ecodiesel 1500 Ram in the US. A narrow Q re the portion of video explaining potential power loss and efficiency loss from excess fuel being used in combustion due to lower combustion temps that would result from egr delete (esp on diesels), IF that is the only modification done & the OEM ECU parameters & programming remain the same. So If I understand correctly, this would apply ONLY if the ECU remains programmed & tuned to OEM parameters and thus the ECU still ‘thinks’ there is a fully operational EGR system in place & functioning as it did straight from the factory. HOWEVER, almost all EGR deletes on modern diesels also include a tuning or remapping of the ECU to deal with that issue; so with BOTH a) EGR delete and b) ECU tune, that issue is resolved, correct? doing BOTH should actually result in more oxygen for combustion, thus higher combustion temps and thus both some INCREASE in BOTH 1) power output (HP & TQ) AND 2) better efficiency (MPGs), correct?
Nicest explanation of EGR. Slow, steady and clear.
Thanks sir planning to delete my egr....luckily i saw ur video....and i understand the purpose of egr ...ur voice sounds like my teacher on college...he is a marine engr officer....
Second Explorer's comments ... THE ABSOLUTE BEST EXPLANATION about the EGR. Thank You Very Much for SHARING THIS VERY INFORMATIVE VIDEO !!!
That was so well explained I've decided not to do an EGR delete on my Amarok. I've had the carbon build up twice in 160,000 klms and now know that it won't be a problem if I drive it like I stole it from now on.
This video deserves MILLIONS of views. FANTASTIC work here. It's so informative
This is the best I have seen to explain how a egr valve works. Very simple to understand. Great job thank you
Man you are very talented. I understand your explanations very well. You know how to explain details. You need to be a teacher.
One of the best well presented videos I’ve seen on this platform. Thank you!
Excellent explanation of the recirculating gas system on the diesel and ICE engine. Thanks for making this so accessible.
Very good explanation. Very informative.
Problem is that only 1% of vehicle manufacturers train their workshops on the cleaning of the EGR systems and intake. Second problem is it adds to the maintenance costs for the owner.
A manifold full of carbon will have huge power losses. I dribe a 3.2 Diesel and cleaned my manifold afyer 75000km the amount of carbon in the inlet manifold was scary. To remove and clean everything tool about 4 hours. Labor rates is the most expensive part of services can you immagine how much it will cost a owner to have this work done every 75000km
When the EGR cooler fails and it will it will add huge cost to the repair bill.
Thank you for recording this video. Your explanation was so simple to understand. You explained like a university professor.
Man, you’re a master! This is the best explanation about EGR available on YT. Very well done!
Kudos sir! Hindi man lang ako inantok. Mas naging attentive pa tuloy ako. More power sir!
This is by far the simple and very understandable explaination i ever came across
The exhaust gas going into the engine (or your torch in your experiment) is reducing complete combustion of your diesel and in your torch the butane. That is why it lowers EGTs. I would just use an uprated FMIC to lower intake charge temperatures, the colder/denser air going into the cylinder, will cool the cylinders more, the ensuing EGT will be lower. I recommend you remove EGR from your ECU map - remap. I took off my intake manifold after 80K miles and it was covered in an oily carbon sludge reducing the intake volume. Fortunately it was not hard and could be removed easily without the need for walnut blasting. The oil carbon sludge leads to compromising the intake butterfly flaps which can then break off and go into the cylinder and scrapping the engine and turbo; not worth the risk...
For me, This is so far the best explanation
Brilliant video - what you failed to mention is that EGR is also used to control combustion overtemp. Diesels EGT runs away under heavy loads - resulting in cracked pistons and cylinder heads. EGR opens to protect the engine from overheating.
Nope. Not true. Over temp protection wether it's oil, water, intake or exhaust is controlled by fuel management.
i was planning to delete my EGR. Thank you so much i stumble on your video. ang galing po ng pagkaka explain nyo.... kaya napa subscribe agad ako sa inyo.
Sir very well explained, ang galing nyo po na instructor. Expert po kayo when it comes to this topic.
Maraming salamat...
Absolutely mind blown by how comprehensive this video was, thank you!!!!
I recently deleted my EGR but after watching this I am considering refitting it. I must admit I didn’t really see any improvement in power after removing and blanking it.
I’ll keep an eye on engine temp now too.
Thanks again.
Guy
Has deleting it affected in anyway
@@jarethbower9665 if I’m really honest, I have noticed no difference. I have an MOT coming up on the 3rd Feb so let’s see if it passes emissions, if not then the EGR is going back. That said, I have also recently replaced the air filter with a good after market one which DID make a difference, now whether the delete works in sympathy with that is a question that may be answered if I switch back plus, when I fit my Vortex exhaust which will move more air, that may also benefit from the EGR delete and may offset the emissions issue… if there is one.
So all a bit up in the air but as of yet, no difference.
So to follow up. I just had my Discovery 2 go through it’s MOT and it passed with flying colours including emissions despite the EGR valve delete. So it would seem it doesn’t do much. I haven’t noticed any increase in engine temperature or any other negatives. I would say there is a very slight improvement in the turbo lag but that might also be due to the performance air filter which I fitted about the same time.
Regards to all

@@garviereso your egr remained deleted?
Brilliantly explained with a clear language! Looking forward to watch more! But when I watch my engine with a OBD-App, I can see, that the EGR is also working in cold engine during idling. No faults in ECU. Greeting from Germany!
I apprichiate your videos and hope you keep making them for the rest of us to grasp a better understanding.
Could I ask what would cause a gasoline and diesel engine to go into high revs or be stuck in high revs? My friends engine is doing this and he said he has tried everytging he can think of...
Amazing clarity of explanation.Subscribed as soon as I completed this vdo. Looking forward to watching all the videos. GOD BLESS U.
A great lecture. I believe I know more about egr and diesel throttle valve than my mechanic now😂 .
Best video i have seen for EGR on TH-cam
Definitely not bored, this is one of the best explanation videos I have seen.
I reached the part where you explained the flames and its colors and damn this deserve a like and follow
Thank you for making it simple ❤️
nailed it. cooler combustion temps can also reduce risk of pistons cracking.
Congratulations... regards from Athens Greece..
Everyday we should learn something new, today I did. I learnt that the engine/air shut off is not just to prevent runaway in a diesel engine. With servo motor control, more can be done. My question is though, could older systems with vacuum control modulate the valve/s openings accurately ? Great video, very informative 🙏
Deserve mo Sir ng maraming views... One in a million vlog ito congratulations 👏🥳 keep watching and support especially Ads from Al Khafji Saudi Arabia 🙏
Maraming salamat sir.
Best explanation of the egr system to date!
Best and most carefully explained account of the EGR valve I've ever watched. You have a new subscriber!
💯best explanation I’ve ever had 💯
Wow bet a few who have had a incorrect explanation are thinking 💩
This is a whole EGR masterclass.
Liked and subscribed ❤❤❤
Great sir
U could have explained ECU remapping when they delete EGR.
just blanking ❌
recaliberate ECM remaping tune 🤝🔥
Problem with that solution is that you can’t find anyone to do a tune for you anymore. They’re all afraid of getting caught. Also, his video assumes the optimal running conditions in either EGR or deleted setup. A tune just turns off the EGR computing so as to allow the engine to run “normally” again without it. This doesn’t change the pros and cons.
Wow
That's a precise explanation by an engineer.
Because of you your videos I did not get a oil catch can thank you !
Please make a video on how to get diesel fuel economy back and engine power back
thank you for that video, honestly, it's the best explanation about the EGR on the TH-cam. your explanation is very precise, I found in this video the information I search for several years.
are you Filipino sir? this is the best explanation about EGR, I own a nv350 & someone suggested me to condemned the EGR , I just laugh coz he doesn't own a car.
ang galing magturo! veryinformative and straight to the point.
Thank you for taking the time to help me understand the EGR system. That took a lot of time and effort.
I was looking for this video a few weeks ago cleaning my egr passages on my 4cylinder honda 2.4 i had the intake off intake plate egr egr passage/water outlet off i was getting im there like swimwear but i couldn’t figure where it was sourced from i eventually decided cylinder number 4 has a passage without confirmation i was right im glad to see
You are a very good educator clear concise and understandable thank you for your explanation
Very well explained. Malinaw ang pgka explaind sa english.... mechanical prof teacher kayu cguru sir. Ur always relate the subject w things w same principle.
Im not bored. So informative. Thank you so much for giving time for this videos.
Salute x 3. The best explanation on egr and the pros and cons of it. Thanks alot buddy.
Good explanation that is why i didn't trying deleting egr,cleaning regularly is better
Ma dude, this is the best egr video on TH-cam. Thank you for that. Subscribed!
Thank you Mr DIYer for a fantastic explanation of how the EGR works The best video I have seen on youtube
