You are single handedly making my todo list even longer😁😆
Hahaha
Same here...!!🤣🤣🤣
2nd that 🤣.. one thing after another 🤣🤣🤣
I love how the entire lifetime’s work of the EGR and emissions control is now running down your driveway into the sewer :P
Physics.
Nah the egr recirculates to return exhaust gases. To reduce spicy emissions. The soot it normal.
Ok Captain Planet don’t you have better shit to do.
One way of putting carbon back into the ground lol
Along with a bit of oven cleaner just to really dirty up the ocean. Clean or at least rinse it in the sink, then it goes to the sewerage treatment plant first instead of straight out to sea in the storm water
Hi George,good vid. just finished cleaning my VW Touareg 2012 inlet manifold and intake chamber. Loosend the worst off then soaked in some industrial degreaser,waterblasted which had it 85% then Mr Muscle and a 30minute soak,waterblasted again and its like new! could drink beer out of it!
I really appreciate this video, no corners were cut!
One of the best vids ive seen in a while. Good description on what to do and how to do it. Showed everything in the process too. Very helpful😎👍
Glad you liked it!
Hi George nice vídeo the idea Mr.M top. I asked you a question in the last video you didn't answer. good work helps a lot
Great video George, smashed it once again.
Thanks man!
Been waiting for this since you told me great video keep it up mate God bless
Welcome man!
Hello! Thank you for the good and informative video! What about the seals? Should I change those after this procedure?
Would love to see a rolling road of a before and after!
Be a good idea to use the hoover as you scrape the inlets . Thanks
Hi great videos ! Can you do a valve cover replacement plz mine has gone if not is it possible to do it myself
I dove in yesterday and took off the inlet manifold. My car 520D is 10yrs old now with 165,000 mileage. I was expecting to see loads of gunk like I've seen in many pictures, but mine wasn't like that. It's clearly been done by a previous owner, and / or all the motorway milage has helped. Of course there is gunk and cleaning it can only help, so it's been educational. But i don't think this is what's causing my mot fail. I'll take it the garage for a diagnostic next, I'm guessing injector problem. Thanks for video.
Based on 5his video, I recently did my VW. Runs sooooo much better now. Thanks Brother.
You’re welcome👍🏻
another excellent video very helpful
Just did my M47 intake manifold this weekend, without a pressure washer.. The previous owner/garage had badly fitted it so it was blowing crap everywhere and low power. Took it off, found all the narrower pipes were clogged, and the main parts about 30% clogged with oily sooty grime. It took a lot of oven cleaner, de-greasers, hot soaking, scrubbing and pushing out sludge with a giant pipe-cleaner thing (intended for cleaning behind domestic radiators).. Cleaned up like new eventually. New gaskets. My hands are grey, so much sludge. Happy to say it's running much better after a clean. EGR blank next weekend, keep it clean and breathing well!
a lot of thinner and petrol did work
Great job dude thanks and greets from turkey
Newer N47 haven't got the swirlflaps at all. Mine is a N47 (E91) from 2012 and the inlet manifold differs a lot from your (from 2008). I cleaned mine manifold at 100 000 miles, and it was definitely necessary.
Super impressed with the oven cleaner. Needing to clean the aluminium intake on my 300TDI as part of cylinder head replacement, so will buy some cans at supermarket 👍. The egr's been deleted on my defender so hopefully it will not get all this engine and valve neck clogging shite in again. Although I do appreciate the EGR does reduce engine temps, which would be more of an issue on a high performance engine like yours; unlike my road going tractor lol.
Didn’t saw were you closing the valves before cleaning the intake ports by turning the pulley?? Pls explain how to.
Love to see this on a 6.4 V8😱
You've saved me so much money man
Thank you mate 👍
After viewing one of your other video's I went on and removed and cleaned the intake on my 320d with 150000km, and it was one messy job. To get the intake out was also a challenge since these connectors with the extra white locking function was really struggling to get away. But finally I got it off. If there were a nicer way to do this to the environment it would be great because all the soot and grime is not the best for flushing down the drain. Some kind of oil separator washing cabin would be great. I checked with a tuner for disabling the egr when tuning but he also strongly suggested to disable the regen and hence also a dpf delete. Whats your thoughts on this, do you really need to disable/ remove the regen/dpf too ? What options do you have with only the crankcase ventilation ?
Hi. Great video. I have a problem with my VW 1.6 diesel engine. When I drive a long distance, after I turn off the engine, it won't start at the moment. I have to leave to cool down for about 1h and than it will turn on. Does intake manifold have to do with air going into engine?
Very good one bro 👏👍
Thanks bro!
wow i learned something here. Thank you so much... i learned that PCV can mix with the fresh air mix and build up into this state. i was wondering why i had so much of this and is something wrong with the turbo ??? which i have replace so many turbos at work from seals leaking oil into the intake or exhaust side ...
Pcv + exhaust gas. Normal with a direct injection engine. (no fuel sprayed on valves.)
Is it not true that these (efficient) flaps cause a smoother stalling of the engine while saving the dual mass wheel? And do efficient flaps affect acceleration in the low RPM range ??? M87 2.0d M47
Ive commented on the other vid, but now want to do the swirl flap job !! But my X5 is a Nov 2006, lgd in spain, why do we not know if me X5 has swirl flaps or not ?? Surely we know when the swirl flaps were deleted !! Today i checked i had the improved PCV, and i do !!, i also cleaned my EGR, so next thing is swirl flaps !! But is it required on my car ????
My 520d has failed mot on emissions. I think the egr needs cleaning. Mine has swirl flaps, do you recommend oiling the flaps or servicing then at all? Should i blank the ports or leave it open? Thanks
I have the M47 BMW powered Rover 75. I seriously need to do this.
Definitely!
hi mate, did you noticed any difference after this procedure?
great video. No link for the foam cleaner.
👍👍👍 perfect
Gunna do this on my M57 330D while fitting blanking plates on swirl flaps. What’s best way to know it’s dry inside after doing it mate? Best to leave it a while after I’m assuming? Cheers 🤜🏻🤛🏻
By the time you assembly everything back together it will be dry enough👍🏻
Do you have to ohysically remove thw egr valve or will just writing it out of þhe ecu work?
Looks as good as a walnut blast brother
Thanks
Just cleaning my merc intakes,egr pipe was almost closed with grime im doing the dreaded oil cooler seals my head is absolutely done in doing it! Crazy stupid German designers! Using plastic in very hot places.Good video ive subscribed.
By the way forgot to mention,im using cillit bang got no mr muscle 🤣
Fan dabby doesey !!
Did u scraped the intake ports with the valves open? i didnt see u turning the engine to close them is all
Ah Rollex missed the live stream.
Hi mate did you notice any improvement in fuel consumption after doing this or in engine "tune"? thinking of treating my diesel to a squeaky clean manifold aswell
Hard to tell
Good video George but I would have rotated the engine to make sure the inlet valves are fully closed the cleaned the intake runners without any carbon falling into the engine
Hey there mark, seems like a silly question but how is a turned over engine done? About to do a manifold clean myself and noticed a few comments about this. Cheers
What a great video..really. My 2005 120d - 161 php @ 217000 Miles /349000km needs this. It's just the time it takes to take the bloody thing apart, and put it all back together that bothers me. Mine is the M47 engine. Just changing the airfilter, left my "jaw on the ground". ..how is that even legal, to construct something like that. 😁. Mine even got those original "strut engine brackets brace bars" on it.....really don't know if it makes a diffierence....just a pain in the butt, when you want to work on the engine.
Technically speaking if a engine has had the egr deleted is the oil mist from the crankcase ventilation important and necessary for upper cylinder lubrication or would a engine run at its cleanest and have its best running conditions if the crankcase vapours were run through a tube to the ground like old engines did? Sorry if its a stupid question but it is what it is.
Some kind of vent is needed to prevent pressure build up (gasses that get past the rings) - those old cars would just vent to atmosphere. These new cars are not really a vent but instead a crankcase vacuum. Its better than a vent, not only do you not have oily vapors openly venting, but it increases the pressure differential for improved ring seal - which allows for lower friction rings and all these engines are designed around having it. I would advise against converting your car to vent to atmosphere. Instead lots of people use catch cans that the vent flows through to stop the oil from getting into the intake without having to remove it
Средство для духовок или каустическую соду применять надо. Ещё можно тёплый димексид.
Great video. Been trying to clean my Smart CDI intake today as I've got a new exhaust manifold and turbo for it. Not thought of oven cleaner, so cheers for the tip. Intake manifold is slightly worse than yours and a bitch to take off. Wish I could spray the oven cleaner in while it's still on the engine 😂
Hi George, I'm just about to start an engine rebuild on a 118d, does removing the egr cause an mot failure? Do you bolt it back on for mot?
Nope👍🏻
I need to do the swirl flap blank and egr delete on my e46 330cd. this has enlightened me to the process no end. afterwards does it need some sort of recoding ? thanks. great video btw
Needs mapped out
Have a B57 giving EGR issues. Need to do this too… can gaskets be reused or is a gasket kit essential before starting?
They usually can be reused on an intake manifold but best practice is to replace them
Thanks bro I've done a lot of maintenance why ur videos on my e81 and x5 30d. Now I'm going to remove the flaps and clean the intake on my n57. Cheers from France
I don’t recommend removing swirl flaps on N57👍🏻
George has an informative vid explaining why you DON'T remove the S/flaps from the manifold. There is a great vid on YT showing how to remove - clean and reinstall the S/flaps....then you can remove the EGR (as George does in his vid) and there wont be any more issues with clogging up the intake AND you get to keep your torque at low RPM.....win win 😄😄
Okay guys ill just clean the intake and check the conditions of the swirl flaps. So I can remove the ÉGR without ans problems? Cheers
@@redrock1963 the advice on removing swirl flaps varies according to age and model of engine. I also wonder how an EGR gets clogged up with carbon and oil. My two 2001 530Ds have clean EGRs and even the manifolds are clean, not perfectly but they do have 170k and 173k miles on them. The EGR does more than just recycle the exhaust gases.
culd u make a video about preformence Manifold Intake pls ? if it exsist on a n47 XD
Doesn’t exist
I think it would be better for the intake ports if you use a brush attached to a cordless screwdriver and let it do its thing
Wouldn't carbon fall through the inlet valves into the cylinder ?( through the inlet valves that are open). Based on firing order it will be open in atleast half of the cylinders right?
maybe, but I expect it will just burn up and go out the exhaust. The soot is not hard destructive stuff.
Instead of removing the EGR valve: isnt it the same if you add the oil catch can from the PCV system? Does the same thing - takes away the oil...?
EGR valve is nothing to do with oil
@@GeorgeAusters True, but you said that if you mix oil from pcv and egr gases it produces soot inside manifold. So if you install oil catch can, there will be no oil to bond carbon together resulting in clean manifold. Isn't this right?
You should pour some petrol inside the plastic intake and leave it for 10 minutes. It work wonders 👌🏻👌🏻👌🏻
Is the oven cleaner safe to use on the plastic? It won't eat into it at all? Is it also safe to clean with hot water like 80*C? I spoke to mechanic who said it could possible melt/ shrink the manifold and a new one would be required... sounds like bs and an excuse to over charge. thanks!
any advice would be appreciated ! chur
I forgot to remove the Maf sensor and the other sensor on the Intake manifold and I wash it With high presssure water…. It can be dangerous?
You mentioned an EGR delete did you also do a DPF delete to avoid it clogging up?
This doesn’t have a DPF👍🏻
@@GeorgeAusters Would you remove DPF if EGR deleted if present?
Car doesnt have dpf it only had egr which is deleted.
#1 remove dpf #2 remove or block off egr #3 install methanol injection #4 install new tune #5 Install crank case breather catch rank
You'll probably fail the annual/Biennial technical test (TUV/CT/MOT...) in many European countries plus it will invalidate the type approval.
🙌🏼
👌🏼
Do i have to make sure the intake valves are closed before cleaning the ports?
Removed carbon deposits amd then use a vacum, but un cam use a small rag to cover the valves,then Vacuum
What stops all that carbon dropping into the engine? Not all valves will be closed at once. Curious, have I missed something?
Carbon is soft and so will be burnt and blown out of the exhaust no problems
M47?
If you do this on an iron manifold, do you have to do anything to prevent it from rusting?
Nope, but you can use heat to burn off the carbon😉
@@GeorgeAusters so it won’t start rusting?
How much would you charge to clean out my 2.2 diesel inlet manifold and where you located?
I don’t currently do private work👍🏻
Use oven cleaner too then use.vacum cleaner to remove foam...
Shouldn't you turn the engine so the valve is closed otherwise stuff gets into the chamber? Or did i miss you telling that :)
Yes if you are cleaning the ports
So and the all crap goes right to the cylinder trough the open valves???
I would say if you were careful what little did go past the open valves would get burnt off quite quickly as it is soft and comparable
It should be mentioned then, some people might get in trouble, better do not touch those intake ports unless you 100% sure valves are closed.
How much would this cost at a garage?
No idea
Does using oven cleaner not harm the plastic like it would aluminium? That’s what’s holding me back
Never ever had an issue👍🏻
@@GeorgeAusters would you advise spraying into throttle body and soak.
Great video thanks. I just did cleaning of my EGR after 160kkm was not so bad....By the way I am wondering how many times are you pumping carbon water on that street...🤣🤣🤣
If you think that’s bad, you should see some of the crap that comes off my car when I wash it👍🏻
is that the intakemanifold of the n47 engine?
btw did you fully deactivate the egr valve or did you only raise the fresh air % rate? greetings from dortmund
Fully removed EGR. This is M47👍🏻
Hello. how many kilometers your car has traveled
This car had covered around 350,000km
George pop down my house mate there is plenty of jobs to sort out on my bmw 🤣
PLS help me , I took the intake manifold apart, and when I put it back together the car wouldn't start. What could it be?
You should always disconnect battery my friend
Bit of a ball ache how much is new 1 ??
Only around an hour to do👍🏻
@@GeorgeAusters having the intake dirty would that cause white smoke ?
I've left my oven cleaner in over night and gonna give it a high pressure wash in a barrel
It should be noted do not use oven cleaner on an aluminium intake it will cause corrosion.
does it boost horsepower
Hard to say specifically
Do the oven cleaner melt the intake manifold if its plastic like yours? Im afraid that it would damage or melt the inside
No
The .most stupid thing is make a plastic intake on Diesels.
did mine today, i used oven cleaner several times and it didn't melt
Dude seems to have a vendetta against egr valves wvery hideo he disses them..
Harsh chemicals immediately into.plastic and crack it later
I have a question guys. My intake manifold had wet oil what could it be
It’s normal
Thanks for the reply, I like your videos a lot I watched all of them I am happy that someone like you is making content and informational videos for the guys who want to save some money and do the job themselves. And one more question is it harmful for some parts to be covers in that same wet oil because my manifold leaked all over the engine and sensors and could that oil come from the crankshaft breather?
So what exactly are the gains of doing this? I know can only be good but you don't mention. Is there power gains or just the overall health of the engine?
Exactly. Whats the gain?
@@ZahedZeeshan think of it as fat in your arteries. is it bad? depends, some of us like to work out and be healthy and others like to sit around all day and eat unhealthy. will doing this to your engine give you more power? maybe not, but it will get close to its original power (assuming your intake manifold is really clogged and your engine can barely breath). will this increase the life of your engine? probably, but who cares if youre not keeping the car for too long. i know my answer is really vague but my point is that some us like to keep our cars (engine) as healthy as possible.
like this you can distroy your engine....it's imposible to remove all carbon and after you mount all on the engine a piece of carbon that remain on inside go in the cilinder head and it's finished
i was supposed to do like that but it say do not use this product on plastique , aluminium etc.... is it safe to use it ? i don t want to break it
I’ve never had a problem with it myself👍🏻
@@GeorgeAusters i did replace head cover joint so i cleann all the hole on top and side with a screw. i will wash the intek now😁
@@GeorgeAusters i did clean like you but with this product for 20 min only , not enough. i took a metal stick remove th rest, it s pretty clean now
why don't you use an ultrasonic cleaner ?
Because I don’t have one
Unfortunately it's not alowed to do this job on the street in my town.....
Even if you sweep it up?
Dose the carbon damage if fall in the engine? Thanks
Should be fine as it’s soft
@@GeorgeAusters hopefully 👍 th
Oil change after 50 miles ?
Thought about soaking the manifold in a bucket of diesel ?
No point, waste of fuel and just leaves it being oily and stinking of diesel lol
Is there not a possibility of oven cleaner making it into your engine? I get that it's pressure washed out, but where's the guarantee that a little might get left behind and cause a problem within?
I honestly wouldn’t worry about it
I don’t think that level of carbon would cause any issues
Have i missed something, i must of, everyone is saying how good video is but wheres the bit, i presume, should be at start, how to take it out, ive just gone to the drive and mine wasnt waiting for me
thought this was carl froch at first ,lol
You should have weighed the manifold before and after
After all of that labor and material I would just replace the manifold.
Yeah if I was doing it for someone else then I would replace it
that part is made of plastic, dirt holds it together
Mental to think how much you spend on a Beemer only to have a plastic inlet manifold :/
Saves weight I imagine
That and pennies too by the looks of it :(
What a filthy little video you made :-D
