- Ok, sorry this is a long one... I’ll be honest, it was a little more ‘involved’ than I had anticipated but not toooo bad.
You can see from the condition of the intake manifold & swirl-flaps that it definitely needed doing 👍
Thanks for the video, I have a method for next time. There is a quick way to clean the intake manifold. This method worked very well and does not damage the plastic. 40 liters of water, 300 grams of washing powder and 1.5 kg of drain cleaner. Mix everything carefully and then insert the manifold for 4 to 6 hours. Then wash off. Finished. You will be enthusiastic. Many intake manifolds have already been cleaned in this way.
Hi mate, I have done pretty similar work on my E70 40d 260.000 km. There was more carbon in the manifold. I did not do any brush but I sprayed egr degreaser, gave it a night to do the work. Then I was able to take the rod out, put out the swirl flaps and clean them. Eventually went to car wash and used jet washer. It got nice and clean. After reassembling my car took shorter to start,it was like 5 secs of that awkward moment when you were thinking what you've done wrong but it eventually stared. Nevertheless - great work!
Sounds like a good job mate 👍
Easiest way to clean the intake manifold is just use a jet wash after letting it soak in degreaser
Take my hat off to you sir.... I think if i had done all that and it didn't fire up I would have burst in to tears lol....
GDI, strikes again. May I suggest you wear eye pro when spraying brake cleaner. Would have luved to see the exhaust immediately post start. Maybe add a oil catch can? Most of that crap is EGR and crankcase blowby.
I was laughing at you at first seeing the amount of disco' going on … . then when the clean-up began I started to take notice. By the end I was suitably impressed.
Thanks for making the video and sharing. I don't even drive a diesel but I appreciate the effort.
Brave, very brave.
I have M57N and hope it won't be this bad when I take it apart but if it is this advice will come in handy! I think I will probably blank off the EGR valve too while I'm in there - the amount of crud it chucks back into the engine is unbelievable! I will also me doing the swirl flat delete which us much easier on the M57, though I think they are better designed on the N57 and less prone to breaking off especially if they are cleaned regularly.
Mate hat off to you trust me I’m hugely impressed I mean it I wish I’ll be like you a real petrol head simply brilliant great job you’ll be a brilliant teacher to some of these useless bmw expensive gits
Looks like you need some engine mounts as well .. the engine movement on idle was pretty obvious.
As he was saying it's idling ok now I was thinking no its not 😂 engine mounts are well shot
Brits literally can't work on cars without a cup of tea
😂
If not a cup of tea, it's Golden Virginia in a Rizla paper.....👍👍👍
We need tea for everything. Reduction in tea drinking is why the empire went down hill.
and muricans can't work on anything without their pissweiser
We go to war on tea lol
FFS I’ve been trying to get my split coolant pipe off but there was a third bolt hidden behind the inlet!! Nice video thanks
Yeah I took off the whole damn intake to take that bolt out to remove the coolant pipe. You actually dont need to take that pipe off. Just remove the bolts against the block to remove the entire system. Even had to take out the ecu box 328D F30 N47
One problem with decoking with valves not fully shut is the mix of solvent and carbon seep into the piston rings and seize them on the piston causing low compression thus requiring a full block and piston strip to clean it out.
Yes, I would advise against spraying any cleaning agents into the intake ports if they are open.
I think I used brake cleaner when I did this, and as long as you don’t spray like crazy it’ll evaporate off pretty quickly anyway - so not a massive risk imo. You won’t be turning the engine over for a good time if you’re in this position with the manifold removed, and any bits of carbon mush that may have fallen into a cylinder won’t hurt the engine - they’ll just burn up when running 👍
The struggling to start is just the fuel pressure building up
George Austers might have left bores open
Nope. It's the dirt making intake valves stay slightly open and letting compression pressure to escape.
Yep 👍
Here’s me who had the manifold out just to put a new packing in and did not clean it at all. 270k km. Had some carbon but the mechanic didn’t have time to clean it. Took him 1 hour to remove and about 10-15mins to put back in. Feel so annoyed that I didn’t get it cleaned.
All good mate but please, dont clean ur intake ports like this ! No liquids, just light scrubbing with vacuum cleaner next to the port u are cleaning on full blast to extract any loose debris straight away. Thats why you had engine start issues with that horrible knock at the end. Best of luck buddy !!!
Awesome job! Did you notice if the engine runs better\smother after the clean? Did this job on my E46 320d, 136 HP engine. The job itself with removal was waaay less painful. For cleaning I just put the intake manifold into a hot bath of water and generous amount of caustic soda (hope that translated well) for 3-4 hours. The solution eats all of the carbon\oil gunk and it looks as new. I now have an 330d F11 and might give a stab at this job myself. Not sure I dare cleaning the channels for the valves though.
How did you crank the engine to get the valves closed before cleaning?
He didn't close the valves
He probably didn't but definitely should have. This is probably why the car took so long to start.
Turn the crank pulley till they shut
You have to reset your MAF-Sensor as well as your Intake itself you muppet. No wonder your car won't start considering the amount of sludge you took out of the intake(btw very nice job). Imagine getting up in the morning at a place you've no idea how you got there. Would you start your day as every other day? That's what your engine thinks after cleaning
how did you clean the open valves mate?
Did the car feel any better
If I’m honest, it feels about the same.
@@Nut_Job. loving what u do always waiting for the next update or new project your on.
Hi, nice work, i have e39 3.0d and i saw the intake, it looks a little bit whith carbon, but i dont know what to do, bc the services shop i think dont make a good job to clean it, it has effect whit black smoke when u clean it? Regrads
Hi. Appreciate it’s an old video but have (or did) you not try a “TerraClean”? They’re supposed to make a huge difference. My DPF is slowly blocking with ash (155k) so about the right time. I’m unblocking the DPF with a removal and jet wash then a TerraClean. I’ll look into an EGR delete too.
Hi there, I never tried a TerraClean & I’m not sure how it works really. If you remove & jet wash the DPF it should be fine after that in theory. Although I agree a EGR delete is good for prolonging your engine life, it would only result in clogging your freshly cleaned DPF quicker. The engine relies upon the EGR to routinely increase exhaust temps & burn-off/regen your DPF, so it can’t do that if you blank/delete the EGR. You’d need to either leave both in ‘stock’ form, or delete both (but you’d have to carefully ‘gut’ the DPF & weld back together to pass the MOT).
But I’m do my self same like you, great job!
Hello. how many kilometers your car has traveled
Love Bmw 🔒
Nice video 👍
Mate - what’s your mileage. My e61 has done 93000 so far and intake and egr are in pristine condition.
It's the emission regulations. It gets worse and worse the newer the cars get. That M57 you have was developed mid 90s...
Are you doing this at a open carpark? Why do major repairs in the open and in public. You deserve a proper workshop with your skill.
I wish I had a big garage 😊
With lots of space & tools 🛠....
Where did you get the cleaning kit from
eBay 👍
OMG you are very clever and I tinkling for my car because is same 530d 😉😉
Hi. Where did you get the brush set from please?
Great video dont think al attempt this.
Thank you !
I need to replase a leaking coolant connectoe flange under the manifold that is held with three torx bolts (as seen on the video). Do i need to take the manifold off?
I think you may need to. It’ll certainly make access easier anyway
@@Nut_Job. Ok. While at it I'm going to clean the manifold. Thanks for the response!!!
Did you use any repair manual or anything?
Can you not dump the whole thing in petrol to soak it and then pressure wash it?
Yes, you could do that. I just don’t have a tub big enough or loads of spare petrol... 😂
You can open the trunk with your key even if battery is disconnected, you just need to add some force to it and it will open right up 👍
How?
I don’t think that’s possible
Did you notice any improvement in torque, power or MPG? Doing same to mine shortly
My timing chain subsequently failed & the cylinder head had to be removed for repair & was acid cleaned at the same time. I’ve done lots of things to improve this car since then & yes it does feel really a lot better. Fuel economy is what it should be for the car, plus power & torque too 👍
You got balls mate doing that did you get round to cleaning your egr
Ran out of time to get the EGR out unfortunately. But it should be a doddle by comparison... famous last words! 😂
The hardest part is removing the water pipes the rest is a doddle I greased my roller in the black cap area before I refitted it worked a treat mate
Regarding the coolant pipes - is there anything special to do there when replacing it? I presume just check/top-up the coolant level...?
I used some bolts to jam in the pipes to stop Water running out and used some new jubilee clips to secure the pipes back on when refitting the egr
Also when cleaning the egr I used a plastic cup like a rattle can lid filled with carb cleaner so that I could stand the egr in the fluid for 30mins before attacking it with small wire brush the reason I said to stand up the egr is because you don’t want to be submersing the motor in the fluid as that will kill the motor
great job. how does your engine run after cleaning? vibration?
After a slightly rough first start it ran beautifully 👍
@@Nut_Job. great. does the engine also run more smoothly?runs better than before?
Well... if you look a bit further on you’ll see that I had another catastrophic problem with this engine & it’s unfortunately still awaiting repair. It’s really unrelated to the carbon deposit cleaning. Yes, in my opinion it did run very smoothly after cleaning & probably helped prevent issues with the swirl flaps clogging up too. Cleaning the intake ports will always be a good thing if done right 👍
u shuld done walnut blasting instead
Your missus must be goin mad with the mess you make on the driveway..
😂 there’s actually very little mess left at the end. Most on the cardboard, and Henry hoovered up loose bits 😉
With special tool and walnuts u make it like new
Alexander Ivanchev BMW Jorssen noord heeft het!
Oven cleaner....worked well for me
Do you use oven cleaner to spray into the manifold intake?
My 07 525i had the same build up .
Hi there, whats the cause of that at 4:33 please
It’s the result of modern turbo Diesel engine design. When your EGR valve opens & sends dirty exhaust gases back through your intake manifold it mixes with some hot oil vapours (from your crankcase breather) and this thick black gunk slowly builds up on everything before your inlet valves.
Exhaust soot + oil vapour = carbon build-up unfortunately.
An EGR delete (illegal in UK) would stop this, but other than that all you can do is take the inlet apart to clean it every 60-80k perhaps?
@@Nut_Job.thanks, I've just done a carbon clean today I noticed a bit different tho, not a lot of smoke come out just noticed some weird smell coming out of exhaust. Thats all
At what mileage did your timing chain fail I have the same engine and just hit 100k? Thanks awesome videos...
Don’t worry... (yet 😂).
My car was at 160k miles when it snapped 😢
@@Nut_Job. Haha that's reassuring I also want to do the manifold clean too.. bought my 430d as ex company car so done alot of motorway miles so hopefully it's not as bad as what yours was
Japierdole 5:50 it's a lot of work and pain in ass xD
That could be oil build from turbo seals leaking , if it’s a soft sludgy,gooey , black mess .>>>>>>>>diesels = oil burners
Put it in the dishwasher :D
Or preferably someone else’s dishwasher… 😂
I think brush bristles would just burn up and be expelled too to be fair..
Not the brass ones though... 😬
@@Nut_Job. no prob just stick somewhere on the top of the piston or whatever. Doubt many bristles came dislodged if any over the course of 1 job. To be fair you probably could of had a professional engine carbon clean for about 100 quid or so..
Yeah, I know I could have done that... but I just doubt they would have shifted the stuff I scraped off yesterday. I might be wrong though, but I was also curious to get inside the intake 👀
I was a bigger job than I expected though really...
@@Nut_Job. It might not of shown it on your first test run, but I would of thought it should run a fair bit more efficiently now. That was indeed, a lot of muck
Did you have a rough idle on cold starts? If so, was this resolved after the clean?
Yes, the idle was slightly uneven before & it seems more stable now that it’s been cleaned out. I suspect it’s because the swirl flaps were so caked in carbon build-up... but it does seem better 👍
what the mileage on that
Adam King 167000 miles he says it around 4:05
It barely started... what the hell? It shouldn't be like that.
NO NO NO NO NO ! ! !
Carb cleaner OR electrical connector cleaner because it is safe on plastic !
NEVER USE BRAKE CLEANER ! ! !
Brake cleaner is way too aggressive and will cause the plastic to harden and become brittle . One sharp jolt while driving and your lovely plastic intake cracks or breaks apart ! ! !
looks like your mounts are shot aswel :D
See here: th-cam.com/video/pajLaWsF6wQ/w-d-xo.html
you are so wealthy
well done, but delete the damn EGR !
I thought about that, but it complicates the DPF regeneration... didn’t quite fancy a DPF delete either
@@Nut_Job. ohh that's irritating, maybe a oil catch can to stop the oil mixing with the soot, its never really the egr that causes the soot, its the breather blow by that mixes with soot
True. I was intending on doing a catch can video, but I got busy with other things... I’ll try & do it soon 👍
@@Nut_Job. Awesome , just found your channel and I love it :)
Must have been almost brown trousers time with that cranking and waiting 😯
Little bit.... 😫
@@Nut_Job. what is your opinion in liqui moly diesel intake decarbonization?
Do you think will make any difference, i see that all the crud is disolving like water in all the reviews but i want to know your specific opinion.
Would you use one?
I’m not actually aware of how it works to be honest. Is it one of those cleaning agents that you spray into the intake?
If it's an ex police car they spend a lot of time idling to power the lights when they are at accident scenes etc , this constant idling is not good for diesel engines , they start to cool down especially in the winter so the egr opens to allow hot air back in to the inlets , this let's in soot and oil vapour in large amounts.
Not many people these days who will give it ago but have you done alot of work on engines before as dont seem to struggle with anything saves you alot of money through the jobs u have done I try but break things lmao.
Was starting to get palpitations watching you stripping it down, then relaxed while watching cleaning section.
However they returned with a vengeance when you tried to start it. Then when you started to look worried 😜
Excellent video as always, should maybe have had health warning at the start though! 🤣🤣🤣
I was definitely getting worried.... and I even cut out some of the parts when I was cranking the engine! 😱
That’s why I included the footage of first start... so you know what it’s like in case anyone tries it 😉😁
Firstly, thanks for great vids - and all respect to your efforts - under the circumstances and conditions.
The very best and most appropriate way of cleaning the intake manifold and all associated parts, is to put it all in an ultrasonic bath. I did that with my n57 parts, were everything was looking like new when I got it back - awesome!!!!
Really enjoyed that great video , are you an engineer by trade you seem to have that methodical way of working about you
Thanks John, I have an electronic engineering background but work with industrial automation in the utilities/gas industry. I love tinkering with my cars for fun 😁
Do not remove the swirl flaps, you'll lose a lot of low down torque and in turn get worse MPG. Already tried and tested by myself.
On what kind of car. Turbo or NA?
The good old fashioned decoke is coming back all DFI ENGINES will have this problem in the future,
i lived beore in north spain and hadn't room for that jobs, always rainning too!!! noW i live in a house in catalonia (pENEDES). i have garage and sun. THANKS FOR SHARING!!!
And everything because EGR 🤯
This is why i blanked mine off.
The main reason is because it's a direct injection system. They wanted to defeat the traditional design and failed. Now these engines will have injectors on the intake that will run from time to time in order to clean up the valves with the fuel. When that's the case, there will be two injectors per cylinder, one on the rocker cover and the other on the intake manifold. Even without the EGR, just with the PCV alone, it will clog up like that eventually. Nothing you can do to defeat the carbon, you can just make it a bit better.
@@hussssshie I don't think that applies to diesels. I know of the older direct-injection petrol ones certainly suffered from carbon build-up. Then like you said they added another set of injectors on the intake to clean up the valves etc.
@@DarrenBoss1984 Nope, just a handful of diesel engines use this system, I think Citroen and Renault are the ones that have tried that. Because diesel is an oil, not a solvent like gasoline.
Hi mate I think some carbon must of gotten under the valve seats and compressions being lost therefore not being able to start. After lots of cranking the valve seats would of cleaned themselves
I know that feeling. Somewhere between consternation and wanting to cry when they won't start.
Lovely Jubbly, yes your car does have those miles on it, but the Police serviced it, imagine if they hadn't.
Great job as always. I love your attitude of tackling anything. I was getting worried for you whilst dismantling, and wondering how you would remember were everything went when re building. Turned out alright, well done.
Yes, me too... I didn’t imagine there would be so many things to disconnect & remove just to get the manifold out. I was a bit concerned too 😧
Funnily enough, that’s why I originally recorded myself doing new jobs on cars - so I could review it if I got lost. It was my daughter who suggested putting them on TH-cam in case other people were interested 👍
Install an oil catch can to help prevent the build up
Delete the egr Valve , it's the egr's fault !
@@ralfrisberg8009 can you block it off with out setting a light?
@@narcissistinjurygiver2932 on new cars you probably need to connect the damn computer and do something !
@@ralfrisberg8009 i have an 03 sl500 and was thinking of just blocking off the port from the exhaust to the egr valve. it was ok on my vw but will just try it on my benz
Hey. Great Video!!!
Have couple of questions, just purchased a 535d with N57 engine, same as youth.
Long story short, how much of a vibration you fell inside the cabin, I have similar issue with the engine when it idle, on camera it shows really well, it's floating, but if you put the hand on the top cover it vibrates, same on the starting wheel, and only when idle on park or drive, and when rpm gos over 800 it feels sealky smooth. just wondering if you ever notice it and if yes, was it there for as long as you had a car?
Engine and tr. mount's was replaced, the air filter duct and housing to turbo was replaced, not engine light, no hick-ups.
will be huge halp if you respond!
Will be posting video on troubleshooting and all the repairs soon by the way.
Thanks!
You got some balls doing that job man....id be shiting my jocks....total respect to you 👌
I cannot believe the volume of crud build up in the intakes! Wonder if you’ll see a performance gain?
Most likely. You could almost compare it to having the intake side ported.
Great job but fuck that. Nothing easy about that job from start to finish.
I absolutely agree 😂😂
I know this is an older video but I'm still going to leave a response.
This is one of those ugly jobs that you have to do. I also believe that this was totally necessary. I was watching someone the other day who was doing the math on what percentage of space that brings in the air to the engine and how much of a reduction in it really was. He calculated that he was losing 45% of airflow due to the carbon buildup.
I'm hoping to get this done this week. I'm not under the clock so I can take the extra steps and do things while I'm in there. I am fortunate enough to have a shop size air compressor add a walnut gun. I also plan on using my power washer. If the manifold wasn't so expensive to replace I was just order a new one.
I did enjoy your video and I made sure to give you a big old thumbs up. I also hit the subscribe button and I'm looking forward to watching more of your videos.
Dude get rid of those swirl flaps! Accident waiting to happen mate
I did 👍
But you didnt touch the fuel system, did you? Why did it give such a hard time to start? Sounded like it had air in the fuel system
Probably cause of that rest of the carbon dirt and shit like that, that was still in the cylinder ports. Once all that was burned off and out of the system, then the car would only burn and work on good and nice diesel again
Im currently doing this on an m57 so this is really helpful. I subscribed anyways based on the fact ur channel is called nut job🤣👍🏽
Good luck with it 👍
If you want to delete your egr valve, DM me.
My turbo wasn't kicking in because the swirl flaps wasn't opening far enough, got a bung off ebay for the n47 and I had to snap the swirl flaps out pain in the arse but definitely worth it and the turbo was back on form
I bet you're glad it's not a V8, eh?
😂👍
Not been serviced rite no oil changes need to run water thtough is very bad design of engine money money ect ECT
Any gurus still active here? I just cleaned the whole intake manifold, the swirl flaps and it's still in limp mode. Why is that? None of the swirl flaps are broken or covered in carbon, the sensors are cleared and carbon free, no check engine, no warning lights on the dash, it's idling really nice..I'm clue less.
I'd say it is quite a risky operation... isn't it? I suppose you did this cleanup before your timing chain broke. Would you say it might have something to do with it? Just guessing... BTW since today i own a 2014 530d f11 190kw :) Let's hope it'll run as long as my old, trusty A6.
The only risky part is dropping something non-compressible into a cylinder port (like a brush bristle) I think. That worried me slightly.
I don’t think that could have anything to do with the timing chain breaking though. It was just stretched & worn out. Your 530d is the same power as mine then, but the LCI version 👍
Best off using compressed air to blast the crud out the intake ports! Still a very Good job bud!!!!
That’s A LOT of carbon build up. What a hunk of junk
i got bored doing this on my 530D E39 , i removed the EGR now im cool ahah
ah you got the baby shark manifold. baby shark do do do do do do
Did you have a weird power loss with no warning errors that cleared itself after restarting the engine? Thanks
You didn't explain how different in general the car fet after your carbon clean of the manifold Intake? Thanks
It didn’t really transform the car or anything, but I think it did run a bit smoother in general.
Wow...that's dirty...mind you diesels are worse than petrol engine in this regard. Best call a chimney sweep! lol
I have a 2009 335d (here in the states) and am thinking of adding a oil vapor catch can like the AUS ProVent system. Is that type of mod popular in the UK?
It’s something that some people do here 👍
I thought about it & nearly installed one, but I do remember that the can + hose route was a bit tricky in this engine bay. Loads of space available in the 5 series engine bay, but it wasn’t a 5 minute job to do it well 👍
Well done did mine on my 330d e92 after 94k 11 years old with my old mechanic friend and yes it was a pain to take out. Took 3 hours to remove , 2 hours to clean and about 2.5 to put back together thankfully the weather was kind. Car started straight away and runs much better now nice and responsive , putting plenty of liqui moly cleaner through it . Good job done
which liqui moly cleaner did you used ?
Did you replace the intake o rings/seals between the manifold and head?
def was town driven on short journeys.......motorway cars seldom this clogged
Remove intake clean it.
Delete egr valve
Decat exhaust
Add water methonal kit (clean intake valves forever)nice Power
Fuel burns much more efficiently with 50/50 water methonal
Or 100% water
aaand remove swirl flaps
