Thanks for a great video and help doing this myself. I bought the BMW adapter and it worked great. To anyone thinking of doing this, go for it! I also recommend buying their wand adapter. I built my own (thinking it would be cheaper and it wasn't!).
Wow! thats a lot of disassembly and work ! After taking apart all that , most likely a vacuum hose will break or something else causing my engine to run worse !
+James Hall - Exactly. The other ports should all be taped over. If the blasting wand accidentally came out of the vacuum adapter during the procedure, some shells would surely end up in the other ports (and everywhere else).
To Fredy - We can't reply directly to your comment - The procedure for the diesels is a bit more involved and actually involves multiple port adapters and blasting wands. We have not addressed this as a DIY yet.
RisjadOktrianji - We can't reply directly to your comment as it was sent via Google. The intake manifold is not a problem. the ports and valves are where the carbon builds up.
***** Nope ...... Since there is no fuel injected into the intake ports on the direct injection engines, any fuel additives would only go directly into the combustion chambers .... completely bypassing the carbon in the ports and on the valves.
Ramon Venegas - We can't reply directly to your comment as it was sent in from Google - Yes, it can, as well as a loss of power, rough idle and hesitation.
I'm in the same boat. I have a 2011 35d, and a 328xi. There's a carbon clean procedure that utilizes hydrogen, and does not require opening the manifold, however the locations in the US are few and far between. Walnut my only option as well.
Hi BavarianAuto, great Video footage of you at work on the BMW turbo Engine i may not have a turbo engine but i still enjoy watching your video's, thank you.
Great video and fun exercise for a weekend morning BUT this made no difference to my N54 engine. 95k miles, regular oil/spark plug/air filter changes but first time for carbon cleaning. I was hoping for a smoother idle but engine runs the same.
Oh sweet Jesus almighty! I thought the engine bay of my E39 525d was fully packed... but this is just on a whole different galaxy level of packed and complicated! By the time this guy was done with just the plastic covers, I would have the intake manifold of my Direct injected diesel already on the table. I don't like overly complicated cars, and it's frightening that one day in the future I will have no choice but to drive these (what then in the day will be slightly older) BMW's with such complicated issues... Jesus almighty indeed, do give me strength in the future! I do hope my E39 525d will run forever lol
"I would recommend performing a fuel injector flush as this vehicle still has solenoid type fuel injectors. It is something that cleans the injector internally from build up, injector tip and also the back side of the intake valve. It is recommended approx every 100,000km..." this is what the SA at the BMW delaership just told me. I wonder if that "fuel injector flush "is the same than the" Engine Intake Valve Cleaning with Walnut Shell Blasting"....
With the new subaru FA20 engine platform being direct injected there will been a rise in carbon build up problems so I will be purchasing one of your kits but I have a product suggestion you should make a shop vac intake valve adaptor for the FA20 subaru motor for purchase the FA20 motor is used in a lot of subaru's new cars and people are going to start looking towards walnut blasting since DI engines have carbon issues
Greeting from Shanghai! Thanks a lot for this high quality video as always. Has been learned a lot from your channel. One question, as I know for N54/N55 engine and all the newer BMW engines, there are small passage holes on each cylinder head intake runners for crankcase ventilation purpose, so is there any risk that the walnut blown into this passage?
which valves need to be open or closed when you go to pressurize the walnut tank? which valves need to be open at the tank in order to shoot out the media when the valve at the handle is open?
Thank you BavAuto for another informative video. I have question as usual. I changed rocker cover gasket on my e38 and noticed loads of carbon in it. My question is, is there any other way of removing carbon from there without sand blasting? Is there any cleaning liquid that can do the job? Many thanks.
Short of scraping or blasting, if you run the Liqui-Moly Motor Cleaner before each oil change and run the Liqui-Moly synthetic oil (highly detergent to the carbon and sludge), with 3000 to 5000 mile changes .... over time, the sludge and carbon will clean up quite a bit. See these products in our online store at www.bavauto.com
Hmmm what if the valve is not 100% sealed, you tapped it so the starter just turns a bit but worse case could the car fire with a little walnut? Also how long is this process?
Went to the site. Cant find the product is it discontinued? Im assuming it leaves the valves dusty with leftover shells powder maybe? If so how would you rinse off the area?
Herakles -- yes it does. It's the PCV / EGR that is causing this carbon. Eliminate them and the valves will be like new forever. I'm not sure why OEMs don't install an oil catch can to lessen this problem. Idiots.
The procedure for the diesels is a bit more involved and actually involves multiple port adapters and blasting wands. We have not addressed this as a DIY yet.
which valves need to be open or closed when you go to pressurize the walnut tank? which valves need to be open at the tank in order to shoot out the media when the valve at the handle is open? you are not showing how to prepare or use the tank correctly
hi my name is Paul I need to do this to my BMW 535i 2009 now do I need to disconnect the positive from the battery or just the negative or how is that done waiting for your reply thank you.
Nope ... no "rinsing". The vacuum does remove all but a few particles that may stick in the crevice between the valve seats and the valves. Any left-over walnut particles will be burned during combustion.
Too bad- someone hasn't developed a way to seal or coat that area of the head- like with a Teflon or PTFE resin after a cleaning job like that- to make the surface slick and oil resistant. There probably are a few coatings or treatments out there that would hold up.
is it common at all to have no start with no cranking after this procedure? or would you say there was something missing in reconnecting everything back?
Very minor walnut shell waste getting into the chambers will have no effect (they will burn up through the combustion chamber and/ or catalytic converter). If a mistake has been made and a cylinder was blasted with the intake valves open, we would suggest that the vacuum adapter be applied and air-only be blasted through the blasting nozzle, directly through the open valves. this should agitate the walnut media and allow most of it to be vacuumed out.
BMW should have redesigned the intake system to reduce the amount of oil taken into the intake ports in order to reduce the frequency of this service. I've had this service (walnut blasting) done on my N54 once and because I have the oil catch can, the amount of carbon was quite less than the images you show.
Yes, a properly designed oil separator system for the crankcase ventilation, would reduce or even eliminate the carbon build-up. The first car we did, was much worse than this one (80K) and had an aftermarket catch can installed.
BavarianAuto There are some really uneffective OCC's out there on the market. The one offered from Burger Tuning seems to be the best one; this is the one I'm choosing once I get the walnut blasting done.
hi sir..i have a problem with my mini cooper s 2012. the computer shows to me " low pressure". i changed the high pressure pump and there is no change with the problem. do u think its because of the carbon? maybe i have to clean it?
You likely just need a bigger compressor. The size of the blasting tank is only reflective in how often you have to refill it. If you run the pressure down and then have to wait for the compressor to run and refill the compressor tank, this is a compressor issue. A blaster uses a lot of air. We can run continuously with the blaster shown, but we have an 80-gallon two-stage compressor. Typical home compressors do work, but you will have to occasionally stop and wait for more air.
+Bavarian Autosport thats pretty optimistic I guess, I spent more than 10 hours to replace the water pump as my first time working on car. thanks for the video btw
Would a (non turbo) 1993 325i e36 with 700k miles on it need this carbon cleaning as well? Currently, No Start with car running fine only minutes earlier. local auto repair shop thought I had bad fuel pump. I told them I've been smelling gas a long time and seen some leaking from electrical receptical on sending unit (full tank of gas) only days before failure.

Lots of issues here & the shops have been going in the wrong direction to diagnose. First steps are to check for spark, injector pulse and fuel pressure. I see no references to these most basic diagnostic steps. Please email info@bavauto.com and note that we requested you to do so, from your youtube comment. and to forward to Otto.
Is this now available for the E90 335d? M57 engine. (I think it is from looking at your website) I have a 2010d with 90,000 km on that I'm pretty sure has carbon build-up issues. If anyone knows of anywhere in the Toronto area that can do this on a 335d for a reasonable price let me know - Budds in Oakville charge around $1450+tax for doing this and I'm not 100% convinced they have a lot of experience doing this. J&R Auto Electronics in Oakville have experience making ECU program modifications to the EGR that will significantly reduce the problem but they don't actually do the decarbonizing at this time.
In theory, yes. If the ports are so clogged that little air can get through, this would reduce cylinder compression due to incomplete cylinder filling. At this point, it would also make the engine practically (or fully) unable to run.
I think that it is ridiculous that a manufacturer would produce engines that require such expensive service in order to switch to direct injection. The small benefit derived from direct injection don't justify spending $1100 every three years just to make the engine cold start and idle smoothly.
+John Ferguson - Yeah, as a long time enthusiast I've owned 5 BMWs over many decades and I have to say, this carbon issue, the HPFP issue and BMW Canada's $500 extortion fee for an importation recall letter has turned me right off of BMW. I won't be buying another one. I've switched to Japanese (Mazda, Subaru & Infiniti). BMW has turned into a damn joke and lost one lifelong customer over their poor design and general idiocy.
OMGWTFLOL The new Honda direct injection engine has a second set of port fuel injectors that are activated under heavy acceleration. The spray of fuel cleans the intake and eliminates carbon build-up. i think that other builders will adaopt the same concept; it seems to make perfect sense. The Honda can idle and cruise at air/fuel ratios up to 41:1 almost 3 times the stoichiometric ratio.
We're sure we will be seeing this on ALL BMW direct injection engines, turbo or not. We will be watching for BMW to release the applicable port adapters for the various engines.
Listen to what they say at 16:37, it makes the engine clean again and run the way it should; much smoother and with a better, more direct throttle response
I notice when I pulled my air intake manifold off my BMW 2011 335D M57, I can not see the ports or valves on the engine? I did notice huge amount of carbon buildup on the ports. I cleaned ports that were massivly clogged and cleaned the swirl ports on the manifold. I also cleaned the EGR and changed the glow plugs while I was at it but I am not sure how to get to the valves? The open ports swerve back in to the engine where there is no line of sight of the valves. I would appreciate the feedback and advice!
Thanks. I have to confess that I felt completely overwhelmed by the complexity of this procedure (terrified is a better word). Is there some preventive maintenance that could stop arriving to this task, perhaps something in the way we drive the car? If not, how any miles before one has to tackle the procedure?
Alfons Llana - It is inevitable that you will need to perform the de-carbon procedure. There is really no way around it. With the vehicles that we have inspected, we are recommending 30,000 to 40,000 miles in order to keep the best performance and efficiency.
Likely somewhat similar. We do have the applicable tools for the MINI engines that are direct injected. Check our online store at www.bavauto.com. Enter your year/model and search "walnut".
No. No one would do this if seafoam worked. This is on the intake ports, and there's no fuel going in there in a direct injection engine. If there were, this problem wouldn't even occur.
This is the ONLY safe way to clean the valves....and yes, fuel no longer touches the valves so no additives or fuel can have any impact. Running only a full synthetic results in a much less severe rate of coking vs syn blends. Our catchcan systems prevent app. 85% of this formation as well. NEVER do a solvent based engine running service!!!! It causes scoring to pistons and cylinder walls!!
You may be listening on an older computer wiith a built-in Mono speaker. Try viewing the video on a mobile device or a computer with stereo speakers and audio.
+ethiopianeyes Since the engine has direct injection, the fuel quality doesn't have any effect. The fuel is injected directly into the cylinder. The carbon is coming from the crankcase vapors being drawn into the intake manifold through the EGR valve. Fuel quality has a big effect with port fuel injection or throttle body fuel injection.
yes the egr valve is the big one. but your shitty fuel in america don.t help ... if you run 87 on a bmw you are a moron . you can even get that bad gas here in europe. the lowest is ussely 92oktane with the 95 oktane being the standard
And this is why Toyota's D-4S is better, direct and port injectors working together, best of both worlds.
However, Toyota does not allege the D-4S system eliminates intake valve deposits. The primary reason for the D-4S is emissions related.
Boy that guys is awfully enthusiastic.
this isnt a vine video or TMZ...
I scrolled down in the comments and saw about $1100.00. Keep up the great videos.

Would running seafoam or another agent into the intake manifold be beneficial in preventing carbon buildup?
This video is amazing. Nice job thanks.
Greeting from Shanghai! Thanks a lot for this high quality video as always. Has been learned a lot from your channel. One question, as I know for N54/N55 engine and all the newer BMW engines, there are small passage holes on each cylinder head intake runners for crankcase ventilation purpose, so is there any risk that the walnut blown into this passage?
which valves need to be open or closed when you go to pressurize the walnut tank? which valves need to be open at the tank in order to shoot out the media when the valve at the handle is open?
So if you reroute the crankcase ventilation tube to atmosphere does this problem go away? 🤔
Serious question: Can this cleaning be achieved with a dry ice blaster? Or would the extreme temperature be harmful to the components?
Amazing video I don't know if I would bother tackling this I'd prefer paying to have a pro do it but it looks doable

excellent job otto I,m going to rent the equipment and give it a shot
Will a kit for the 335d be available in the future?

Hmmm what if the valve is not 100% sealed, you tapped it so the starter just turns a bit but worse case could the car fire with a little walnut? Also how long is this process?
How long did you spend on each cylinder?
Geez.. Great video.How much would the dealer charge?
I'm glad you shared this video, although in order to DIY it requires a large investment.
Of course, it is still much less than one service at the dealer!
BavarianAuto
Plus, you'll most likely have to repeat the process again during your ownership of the car, so the overall cost is very low.
Could the crankcase vent have a catch can filter installed inline to help?
what are the dangers of dropping walnut media into the engine? what's a best practice for checking to make sure valves are closed?
+Jeff Sol ah I see, thank you
Money Mac .....lololooololol
Is there anything that can prevent the carbon to start? Perhaps a spray of Throttle body cleaner in the intake while the engine runs every oil change?
Recommend a oil catch can?
Went to the site. Cant find the product is it discontinued? Im assuming it leaves the valves dusty with leftover shells powder maybe? If so how would you rinse off the area?
Is this why installing an oil catch can is really important? Does it slow down this from happening?

Isn't there any type of *"rinsing"* procedure of the ports afterwards? The ShopVac alone couldn't remove *all* dust & debris by itself.
Nope ... no "rinsing".
The vacuum does remove all but a few particles that may stick in the crevice between the valve seats and the valves. Any left-over walnut particles will be burned during combustion.

+HUBBABUBBA DOOPYDOOP nanotechnology perhaps one day will do just that
There's already coatings out there that will do exactly that. The only thing stopping anyone from doing it is cost.
is it common at all to have no start with no cranking after this procedure? or would you say there was something missing in reconnecting everything back?
Do you happen to have any Audi FSI kits at all? Thanks
N54 has to do this very often, usually caked on. But many reports say n55 are clean even at 75k miles. I'm at 98k on my m235 now...hm
What are the adverse effects if any, from walnut fragments entering the combustion chamber?
Very minor walnut shell waste getting into the chambers will have no effect (they will burn up through the combustion chamber and/ or catalytic converter). If a mistake has been made and a cylinder was blasted with the intake valves open, we would suggest that the vacuum adapter be applied and air-only be blasted through the blasting nozzle, directly through the open valves. this should agitate the walnut media and allow most of it to be vacuumed out.
Do you sell the oil canisters so I wouldn’t have to do this again after it is cleaned?
Anytime the intake is removed, is a good time to replace the starter. Especially on E46 engines.
wow that interesting , I would like to try one day.
BMW should have redesigned the intake system to reduce the amount of oil taken into the intake ports in order to reduce the frequency of this service.

Is this now available for the E90 335d? M57 engine. (I think it is from looking at your website) I have a 2010d with 90,000 km on that I'm pretty sure has carbon build-up issues. If anyone knows of anywhere in the Toronto area that can do this on a 335d for a reasonable price let me know - Budds in Oakville charge around $1450+tax for doing this and I'm not 100% convinced they have a lot of experience doing this. J&R Auto Electronics in Oakville have experience making ECU program modifications to the EGR that will significantly reduce the problem but they don't actually do the decarbonizing at this time.

Can this condition get bad enough to cause a loss in cylinder compression, and cause a car not to be diveable at all?
In theory, yes. If the ports are so clogged that little air can get through, this would reduce cylinder compression due to incomplete cylinder filling. At this point, it would also make the engine practically (or fully) unable to run.

I think that it is ridiculous that a manufacturer would produce engines that require such expensive service in order to switch to direct injection. The small benefit derived from direct injection don't justify spending $1100 every three years just to make the engine cold start and idle smoothly.
+John Ferguson - Yeah, as a long time enthusiast I've owned 5 BMWs over many decades and I have to say, this carbon issue, the HPFP issue and BMW Canada's $500 extortion fee for an importation recall letter has turned me right off of BMW. I won't be buying another one. I've switched to Japanese (Mazda, Subaru & Infiniti). BMW has turned into a damn joke and lost one lifelong customer over their poor design and general idiocy.
OMGWTFLOL The new Honda direct injection engine has a second set of port fuel injectors that are activated under heavy acceleration. The spray of fuel cleans the intake and eliminates carbon build-up. i think that other builders will adaopt the same concept; it seems to make perfect sense. The Honda can idle and cruise at air/fuel ratios up to 41:1 almost 3 times the stoichiometric ratio.
this car has such sweet acceleration though. It's way worth it. Without even forcing the engine 50% of the capacity itll smoke most other cars
Toyota is japanes and better than all those you just listed. Infiniti is made by Nissan and Nissan is junk.
toyota sucks dick. reliable, but ugly. bmw kicks its ass all the way. put your camry up against my '12 m3 comp package and ill take u any day.
By doing this it will restore your horsepower?
Jose ph yes
16:50 yea, it is a truly DYI task... As long as I own BMW
Does the N51 on the 328i suffer from this too?
We're sure we will be seeing this on ALL BMW direct injection engines, turbo or not. We will be watching for BMW to release the applicable port adapters for the various engines.
what the effects for driver. if i clean the in take? only clean? or??
Listen to what they say at 16:37, it makes the engine clean again and run the way it should; much smoother and with a better, more direct throttle response
Thank you!
Is that 20 lbs or 40 lbs abrasive blaster?
I got a 25 lb box of "fine walnut shell media" from Harbor freight. Worked great.
I notice when I pulled my air intake manifold off my BMW 2011 335D M57, I can not see the ports or valves on the engine? I did notice huge amount of carbon buildup on the ports. I cleaned ports that were massivly clogged and cleaned the swirl ports on the manifold. I also cleaned the EGR and changed the glow plugs while I was at it but I am not sure how to get to the valves? The open ports swerve back in to the engine where there is no line of sight of the valves. I would appreciate the feedback and advice!
why do you only close the intake valve and not both valves?
whoa dude did you just really think this engine has inlet and outlet on the same side??
omfgwtfbbq90 lol i got a sudden brain fart....Stupid me
I'l like to see the same video for BMW F30 engine
Is this procedure factory approved?
Yes it is ... the port adapter is a BMW service part.
Thanks. I have to confess that I felt completely overwhelmed by the complexity of this procedure (terrified is a better word). Is there some preventive maintenance that could stop arriving to this task, perhaps something in the way we drive the car? If not, how any miles before one has to tackle the procedure?

- It is inevitable that you will need to perform the de-carbon procedure. There is really no way around it. With the vehicles that we have inspected, we are recommending 30,000 to 40,000 miles in order to keep the best performance and efficiency.
+Alfons Llana - The best way to avoid this is to NOT buy a direct injection BMW. VW/Audi 2.0T engines are notorious for this too.
On mine e46 intake manifold has a lot of carbono....
is it same for s62 engine?
No, the S62 is NOT direct injected.
$1100 for this service on a 6 cyl BMW ?? what does this cost for a 2009 mini s ?
Likely somewhat similar. We do have the applicable tools for the MINI engines that are direct injected. Check our online store at www.bavauto.com. Enter your year/model and search "walnut".
Also, can't you just turn the crankshaft bolt to turn the engine and close the valves? Or is the engine bay, let's just say, too tightly packed? -_-
Depends on your car but mine was too hard to get to. And bumping the starter was a piece of cake. Super easy.
Would this work for 03 745li ?
Your 745i (N62 engine) does not have direct injection. Therefore, it does not have this carbon problem.
BavarianAuto could you suggest a service to clean up carbon and varnish 525i e39 with 112000mi.
Bro I need help wait my car bmw 335i 2007
You must make sure that the valves are closed!!
Yes, as noted in the video.
Ok by bad
can't you just use a fuel system flush like seafoam or something ?
No. No one would do this if seafoam worked. This is on the intake ports, and there's no fuel going in there in a direct injection engine. If there were, this problem wouldn't even occur.
This is the ONLY safe way to clean the valves....and yes, fuel no longer touches the valves so no additives or fuel can have any impact. Running only a full synthetic results in a much less severe rate of coking vs syn blends. Our catchcan systems prevent app. 85% of this formation as well. NEVER do a solvent based engine running service!!!! It causes scoring to pistons and cylinder walls!!
whoa, spooky.

You may be listening on an older computer wiith a built-in Mono speaker. Try viewing the video on a mobile device or a computer with stereo speakers and audio.
N62 engine
The N62 V8 does not have direct injection. Therefore, it does not have this carbon issue.
fucck this is a lot of work
any indy that does this in orange country
We have no contacts in the area, but we would certainly assume that there are shops prepared to do the walnut blasting.
i found a shop that does it for 350$ is that a fair price ?
GangGreen_714 My local BMW dealer charges about $600 (they are in Virginia), so I would say that's a great price.
Tom Sanderson daaaammmmm pricey ... i found a guy that works on n54/n55 engines he did this for me for $250
GangGreen_714 craigslist? that guy? thinking about it
run highest grade octane fuel to eliviate build up. 91 or 93. "87 builds carbon daily."
+ethiopianeyes Since the engine has direct injection, the fuel quality doesn't have any effect. The fuel is injected directly into the cylinder. The carbon is coming from the crankcase vapors being drawn into the intake manifold through the EGR valve. Fuel quality has a big effect with port fuel injection or throttle body fuel injection.
+ethiopianeyes this has nothing to do with fuel grade/quality.
yes the egr valve is the big one. but your shitty fuel in america don.t help ... if you run 87 on a bmw you are a moron . you can even get that bad gas here in europe. the lowest is ussely 92oktane with the 95 oktane being the standard
they use a different octane reading System: US 91 octane equals europes 95 octane; US 93 octane equals europes 98 octane...
