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!
@@benndarayta9156 it's better for the engine. An EGR sends exhaust back into the intake to re-burn it to reduce NO2 emissions at low revs. With less Oxygen in the intake the engine burns less efficiently. Diesel exhaust is sooty and oily so it builds up in the intake and around the valves over time causing problems. Removing the EGR keeps your engine cleaner for longer, increases efficiency and performance a little too. You will need to get it mapped out of the ECU or you'll get engine lights and IF you have a DPF it's more complicated as the EGR is involved in keeping the DPF from getting clogged up. My 2003 320D with an M47TU engine did not have a DPF from factory so it wasn't a difficult job.
@@benndarayta9156 Nah the EGR sends exhaust gas back into the air intake at low revs, tis re-burns the exhaust gas to reduce NO2 emissions. Unfortunately this makes your engine less efficient, and as diesel exhaust is sooty and oily it causes your intake and valves to get clogged up. If your engine is running poorly or the EGR valve gets stuck open it clogs everything up and causes all sorts of problems. A diesel engine with EGR removed will last longer and burn fuel more efficiently.
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
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.
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!
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.
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
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?
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?
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 ...
when doing the cleaning on the intake ports, isnt there a chance stuff falls inside the engine? im a complete n00b so pls enlighten me. have seen other videos were they talk about being careful so the valves are not open and stuff falls down. but then again im a n00b and dont know how this egr/intake stuff works :D im kinda keen to clean my a6 allroad c7, as im sure its pretty gunky in there as well
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
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!
Lmao 80c too hot for intake manifold... You know just the plastic engine covers on many engines might take between 100-190c daily in use with no problems. Why would the intake manifold be weaker than a stupid beauty cover?
@@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?
A word to the wise. It should take an inlet manifold a very long time before it ends up in this state. Under normal operating conditions with an engine in good running order you wouldn't expect to need to carry out a cleaning procedure until the car has covered maybe 100k miles or more. A caked up intake manifold is usually more indicative of there being a fault somewhere, usually related to the EGR system, although it can also be from excessive crankcase gasses or a diesel injection or depollution related issues. Basically anything that creates excessive carbon or oily deposits to be generated, but simply this can be due to a poor servicing routine!
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.
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
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
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 ????
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?
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
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
Great clear video 👍. Whilst the cleaning looks easy enough, unless you are a mechanic Joe Average is not going to have the skills to safely remove and refit the intake manifold. 😢
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 ?
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?
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 🤜🏻🤛🏻
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
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 😄😄

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
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?
@@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.
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.
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...🤣🤣🤣

Would you recommend fitting a catch can after doing this?
#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.

great video. No link for the foam cleaner.
Do you have to ohysically remove thw egr valve or will just writing it out of þhe ecu work?

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.

hi mate, did you noticed any difference after this procedure?
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
Be a good idea to use the hoover as you scrape the inlets . Thanks

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
Great video George, smashed it once again.
Thanks man!
You should pour some petrol inside the plastic intake and leave it for 10 minutes. It work wonders 👌🏻👌🏻👌🏻
Love to see this on a 6.4 V8😱
can i also do this with a petrol intake manifold? Golf 7 gti 2.0 TSI
Yes
Well done, thank you for sharing 😊
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
Would love to see a rolling road of a before and after!
why don't you use an ultrasonic cleaner ?
Because I don’t have one
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
Bit of a ball ache how much is new 1 ??
Only around an hour to do👍🏻

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
It should be noted do not use oven cleaner on an aluminium intake it will cause corrosion.
You mentioned an EGR delete did you also do a DPF delete to avoid it clogging up?
This doesn’t have a DPF👍🏻

culd u make a video about preformence Manifold Intake pls ? if it exsist on a n47 XD
Doesn’t exist
Hello. how many kilometers your car has traveled
This car had covered around 350,000km
I've left my oven cleaner in over night and gonna give it a high pressure wash in a barrel
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
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 ?
I don’t think that level of carbon would cause any issues
Fan dabby doesey !!
Ah Rollex missed the live stream.
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.
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.
You should have weighed the manifold before and after
that part is made of plastic, dirt holds it together
George pop down my house mate there is plenty of jobs to sort out on my bmw 🤣
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👍🏻
