Nice Jake. I've been curious what all this talk about walnut blasting was about, it didn't make sense to me at first. This was cool to see it in action. Doesn't look like a tough job, just time consuming.
Looks like you have a pretty nice setup all around, time to get yourself a car lift.
Subscribed.
Thanks Eric! I'm glad I could shed some light on the process. Funny you mention the lift... I'm really looking into a MaxJax setup or a Atlas BP9000. MaxJax would fit as-is. BP9000 would require me to notch the ceiling a few inches to fit the posts. My garage ceilings are slightly lower than 9'.
Sick video, really in depth. We need more BMW content like this on youtube. Subbed.
Thanks! Welcome aboard. More content coming, I'll try to make it just as in depth as this was.
Awesome video! Just finished doing the IMS bearing and clutch on my old Porsche Boxster and sold it, now excited to get going on an '09 135i I just bought - fixing oil leaks and giving this walnut blast a go. Super helpful video!
Awesome and very detailed video! Doing some 'studying' before I pick up my 335i
Thanks! This should help once you get your 335i!
5 minutes in and I already feel the pain of losing the air box clip in the engine bay lmao
Literally the worst 😅
I loved watching your fix for sluggish valves, however, your EGR was the cause for the problem in the first place. I would love to see your fix for the root cause.
How would you go about fixing this the EGR?
I'm going to have to do this to my 2008 335i. It's at 127k miles and I guarantee has never been done. I feel like this car just CONSUMES gas and it's all stock internals right now. I'm hoping this will help with a bit better gas mileage. Great video!
Did it help?
@@skylinerthirtytwo2683 it did help. The car runs way smoother now. This did fix part of the fuel economy issue I was having, but I also had two leaking injectors. Once I replaced my injectors and cleaned the intake valves it gets the gas mileage it’s supposed to! Definitely would recommend doing this cleaning especially if it’s never been done like mine.
Mannn...my 2012 Sorento needs this. Did the intake valve cleaner. Had to buy new cats. But...this.....is deff what my engine needs
Nice description for anyone wanting to DIY this! Keep up the great vids!
Thanks Bob! Happy to help.
@@jake_spence Can you give me the brass fitting adapter part numbers for the blaster gun please?
Turning by hand is the best option. Good video anyhow
Each cylinder must be at tdc
Great progress Jake!
Thanks Nico!
Man, those intakes looked like the inside of a coal mine. I've changed my blacked out my index 6/7 injectors after 60k miles for a set of 12s and got better power delivery and fuel economy right away.
Yeah, they were bad! And that's good to know. I'm going to try to use these index 7 injectors until they take a crap.
From now on use Liqui Molly DI Jectron fuel cleaner it works.
Man if only I had money for your Paterion, hopefully my likes and sub. Will grow your channel
Much appreciated! I appreciate you following along and watching the videos.
Great video, Jake, thank you!
Glad its helpful!
Any idea why my walnuts don't get shot out of the gun? I have the oem wand..... Is it my compressor?
I'm not sure. Is it hooked up properly? Could be the compressor if so.
@@jake_spence yea its weird, I've even tried two different media sprayers..... My compressor is 114litres p/m at 110 psi.
I have no water seperator in the line but, I read that could cause the media to clump up....
great informative video. now that all's clean have you considered dribbling in 100 to 200 ml of water via a syringe every 6 months or so to keep the intake/ports/valves clean?
I don't think water would keep them clean. Maybe some seafoam or something like that tho!
It’s always going to take a combination of chemicals, and media blast. That is why we charge 500-600 to do this.
I know n54 always have this caked on, but people are reporting n55 , almost don't even need cleaning. Even at 75k miles, I have a m235 with 98k miles now, any input?
It doesn't hurt to check, but I know N55's don't require as much cleaning.
hoping that you still reply to these comments. I just recently bought the same blaster but realized that i need to attach a wand. I stumbled onto your video, but the link for the brass fitting is dead. Do you still know where I could find that brass fitting to attach the wand to the gun?
Just got done doing mine on 135k
Nice! Good thing you got it taken care of.
Fantastic video bruh! I got me an e93 335i at 52k miles. Now considering that it's only 52k miles, should I walnut blast? Every now and then it goes into limp mode and throws the 30FE boost pressure too high error. What do you reckon?
Any idea how strong of a compressor I need to buy, I’m getting one this weekend at harbor freight, the blaster kit at harbor freight says min air requirement 3.5 cfm @ 50 psi but I’m a total newbie to compressors, i read from the other comments that others had issues at higher psi etc etc I’m working on it this weekend hopefully I can get some responses from experienced people in the n54 community like yourself. The instructions in the blaster say “adjust the air compressors output regulator so that the air output is enough to properly power the tool, but the output will not exceed the tools maximum air pressure of 120psi at any time. Adjust the pressure gradually, while checking the air output gauge to set to the right pressure range.”
But what is the “right pressure range”?? Under general instructions it says 50-120 psi which is a pretty big difference.
Which leads me to my original question how powerful of a compressor do I really need? I’m trying not to buy a huge tank if I don’t need to since 1. It costs more and 2. It takes up more space in the garage.
I'd definitely recommend a larger compressor that has a lot of pressure. With a small tank, it'll be constantly running and refilling. With minimal pressure, you'll spend forever blasting the valves. I'd use as much pressure as you can. Good luck!
Did you use fine or course walnut shell? How about cleaning up the turbo as well?
Are there any risks from bump starting the engine? Can the engine actually start running?
I don't believe so. Not with the intake disconnected.
What's the main cause of this? Poor fuel quality? Short drives?
It's due to the direct injection. Instead of most vehicles that have port injection, this car sprays fuel down directly into the cylinder. With port injection, you'd be washing the intake valves with fuel, but this car doesn't do that.
Current is index 12
Yup! That's what I have in my 135i.
Do you think the oil catch can helped in any way?
Maybe some, but it is not a preventative fix.
I'm thinking about doing this, but by doing this, are you chancing the valves to start leaking oil? I have a 1998 528i. I want to install an oil catch can, due to my oil burning, and also chance my power steering
The catch can, was it checked? It didn’t seem effective.
It did catch some oil, but it is not a 100% prevention method. The BMS catch can that is installed in the car is for the high side (boost) PCV system. It will catch vapors when you are in boost, but does not function when just driving normally around town. You can install another catch can on the low side to capture vapors during both vacuum and boost. This would be much better at keeping the valves clean. BMS offers the second catch can setup, that way you can run dual catch cans. I plan to do this in the future.
Mine just hit 104k..I'm wondering if it's time to take it in
So the state of your intakes means the oil catch can is 100% pointless then?
Not pointless, because it does catch oil. But it is not a 100% prevention method. The BMS catch can that is installed in the car is for the high side (boost) PCV system. It will catch vapors when you are in boost, but does not function when just driving normally around town. You can install another catch can on the low side to capture vapors during both vacuum and boost. This would be much better at keeping the valves clean. BMS offers the second catch can setup, that way you can run dual catch cans. I plan to do this in the future.
Were there any dtc's because of this?
How come I can't find *ANY MECHANICS* that know anything at all about this stuff?! I'm so tired of mechanics *blaming ME* for my car problems- telling me I idle too long or that I obviously don't change my oil enough, when I do my oil changes every 5000 miles, and STILL I get yelled at for dirty oil!
current injectors are index 12 right?
Yes, but this car has older injectors.
Would you recommend the new pure 600 twins from pure turbos?
Yeah, I would trust anything from PURE. These are what I would recommend: bit.ly/2Q5MlHp
Did you get misfire before and rough idle
Does the N55 also need this? Is there a certain mileage that the effects are noticeable?
Yes, but the N55 PCV system is better than the N54, so they stay cleaner longer. I would still recommend it to be done at 100k miles and every 50-75k after.
Did you have any misfires? I’m getting a random misfire on cyl 5
It might be a capacitor on the DME depending on your model year. Also could be coil pack,spark plug,or leaking fuel injector(mine was a Injector)
Does this also need to be done on the b58 engines?
Do Mazda’s need this too?? It hiccups a LOT when I turn it on, and I just got a new battery 😖
I don’t know anything about cars, so don’t laugh at me 🥺
I'd run sea foam through the throttle body and take it for another rip you'll be surprised.
What a terrible engine design failure..Direct injection was designed for perfomance and economy but what's the point if this has to be carried out every 50k miles at a cost £250...any fuel savings costs totally wiped out
And this entire process can be avoided by having dual injection...
Yup! Port injection is an option too.
Quick question, I am at 74k miles, (N55) do I need to do walnut blast for sure...???
It never hurts, but might not be 100% necessary. N55 has a better PCV system so the valves don't get caked as bad, but they still need to be cleaned. I'd say you should have it done by 100k.
Jake Spence I see. Thank you so much for the reply!! I will do that at 100k miles. !! Awesome video keep up the great work!!! 🔥🔥🔥🔥
@@sungillestlee63 It will not hurt to do them early and will make it less of an ordeal than at 100K miles.
Good jod👌
Thanks Louis!
How healthy is it being exposed to all that carbon, having it all over yourself, and breathing it?
You're not really being exposed to it. I always recommend a mask or ventilator, but more so because of the walnut shells and debris.
Fuck that! For how long it took you with all the gear etc it would take me at least twice if not 3x the time I'd rather take to for a carbon clean and spend the 100/150 quid or so
Whoever disliked this video probably switched to port injection
@Anton Zuykov lol lexus is boring, not in the same league as N54
Hahaha
Lol my 98 b5234t 5cyl turbo eats these n54 for breakfast with port injection and water meth. Running mid to low 12s. No carbon build up whatsoever. Pulled a 200k motor w/ intake valves shining. VW/audi are even worse 30k service..
@@ogfromutube9649 you're probably racing stock n54's lmao
@@erikmoralesrenteria2464 nah I think he meant to say n52
Damn dude that thing looks like it's been smoking a pack a day for the last 10 years
LOL true!
Tj Semeniuk I was thinking the same thing😂
My 135i has 160k original miles. I’m anxious to see how bad the valves are. Great DIY!
Yikes! Hopefully it's been done before, otherwise you're in for a treat like I was 😬
Can you update some of the links for the Walnut Blasting parts? There are a few links=, (Brass adapter fitting and vacuum adapter and blasting wand that are no longer working). Great Vid and thanks for the guidance.
Yeah new part links would be nice... Specifically for the wand to attach to the harbor freight gun.
Yes I need the same thing. I bought everything at harbor freight and need the brass adapter fitting part numbers.
This video confirms that the catch can on this car did not prevent build up...am I wrong in assuming aftermarket catch cans are installed to keep the intake valves clean?
Not pointless, because it does catch oil. But it is not a 100% prevention method. The BMS catch can that is installed in the car is for the high side (boost) PCV system. It will catch vapors when you are in boost, but does not function when just driving normally around town. You can install another catch can on the low side to capture vapors during both vacuum and boost. This would be much better at keeping the valves clean. BMS offers the second catch can setup, that way you can run dual catch cans. I plan to do this in the future.
I have one installed and it fills up way more than that every 10k miles. I installed mine after my first intake blast at 60k. At 130k miles now and idle is still perfect. But, I do want to investigate.
@@jake_spence This is correct. If you look inside of ports 3 and 4, there are two runners that also vent crank gas back into the intake ports. For the future, that black electrical box under the throttle body is easy to get out with a few 90 degree picks, contrary to popular opinion.
They are designed to catch your hard earned money. They are useless, and only clutter up your engine bay, and introduce new potential failure points. Turbo engines will always have oil in the intake tracts. It is the nature of the design.
I’ve been working on these cars for over 15 years. Never seen a catch can do anything useful. Folks just feel good when they open up that little can and see it full of oil. It’s a placebo effect. Just unplug a charge pipe, and drain that! Same effect, because I assure you, that oil is still making it inside the engine.
But hey it’s not my money, so to each their own.
Not necessarily true. My charge pipes,intercooler, and intake manifold/valves are squeaky clean with mishimoto baffled can amd snow performance wmi. But i have port injection. Utilized stock pcv box with larger 1/2 tubing to catch can then routed back to fresh air pipe. Fresh air pipe has a ptc heated element to keep any leftovers vapors liquified.
The link to the adapter for the gun isn’t working l. Do you have another?
Getting this done on my vw mk6 gli, it’s stage 2 an 140, 000 miles and never been done, it
Actually stalls on cold starts occasionally
Can’t wait to see how bad it is
And how it drives after.
But does that also clean the egr valve?
Would have been cool to know about all the stuff connected to intake manifold underneath.
Bmw 335i gang! I definitely need that done myself!
Get 'er done!
Me too!! On my 2007 335i🤓
Owner of the car has a dinan cf air box but a stock charge pipe? Damn my stock charge pipe failed so early
Don't worry, I have an aftermarket charge pipe... just need to install it :)
Great Video Jake but, thats exactly what I was thinking... $1000 intake and a plastic CP lol ;)
150k and never done. I’m taking mine to a reputable cleaner for $350 though lol. This does not look like fun at all and I can’t wait 5 days for my daily!
Good on you for getting it done ASAP now! It's not a terrible job and can be done in a few hours if you're not getting distracted and having to film like me, lol.
$350 where? im getting quotes $600-800 for walnut blasting on my 335is.
Paulo Brandao, what city and state you live in?
LoveMe2Tmes Southern California, LA county
look up No Limit Motor Sports in La Habra on Yelp and ask for Alex. Bmw expert and reasonable prices
Very helpful! Looking to have this done on my 335is. Probably going to have it done at a shop, but at least now I understand what's involved!
Glad I can give you a peek at the process! If you can find a trustworthy shop that will do it for a reasonable price, definitely worth dropping it off!
How much are you expecting to pay for this job on your 335i ?
Could you use a socket and turn the crank bolt by hand as opposed to jumping the starter over?
Yes you can.l
I like the channel bud! I have a 135i n54 myself. Considering going the single turbo route. I saw u did a video on the 335i quarter. Where’s the 135i quarter? Keep up the good feed!
Thanks man! 135i content is coming soon, I'll be bringing that to the drag strip in the next couple weeks, so stay tuned!
Damn!!!!! Nice job man now you got me interested in checking mine and doing this on my 135i some day
Thanks man! It's not a bad idea to check on them if you don't know when/if they've ever been done.
Imagine non-car savvy people when they go in for service and are asked, "would you like for us to clean your engine with walnuts?" This was a great video, though. I am wanting a car with a GDI engine and I'm a little weary of higher mileage ones for this exact reason. But I don't want to buy new.
Okay I'm convinced... I ll clean my car up a bit starting tomorrow
Do it!
Jake Spence, please update your description section. Some of the links to the parts you used to build the valve sand blaster are dead.
I hope you're happy, young man... all those homeless walnuts shivering in the cold just so you can have clean valves and a few extra hp. Also, keep up the great work and enthusiasm -- looking forward to your next video!
Lol thanks! I have another awesome maintenance video dropping either tomorrow or Thursday.
Man those valves were probably the crustiest I’ve ever seen tbh. Satisfying end result though. Great work.
Agreed! Thanks. Took a lot of elbow grease to get them so clean. But worth it.
I got 07 335 e90 W/sport pkg silver just like yours. has 72,000 completely stock. Super jealous wish I could do some mods like you’re about to do. Love the videos!
Sounds like a nice, clean car! I'm glad you're enjoying the content so far, you're gonna love the videos coming up!
Love the video, you just gained a subscriber, thanks for posting it. It's definitely going to be helpful as I need to do it on my 09 135i currently at 98k. I had to replace my starter motor recently so I was able to peek at my carbon buildup. It's a little worse than your 1'er at 90k so I'm definitely excited to get this done myself. Does the air compressor have to be 175psi? I currently have a 20gal 125psi Central Pneumatic Oil-Lubed compressor and was wondering if I need to replace it for a 175psi one, although I'm hoping I wouldn't have to. Keep those awesome DIY videos coming!
Welcome aboard! The more pressure your compressor has, the more powerful the blaster kit will be. I'm sure you'll be able to do it with your current compressor, but might just take a little more effort. I hope that makes sense.
Did you block the holes that lead down from the PCV? Some say if you don't do that you'll end up with walnut shell grains inside the valve cover. I'm doing this myself as we speak and trying to get an answer to whether this is necessary or not...
If it's never been walnut blasted the car can stall at low rpms at a red light or at a stop assuming that it's not the vaccuum lines or the hpfp if they've been changed
True, but this one never did that. I do want to replace all of the vacuum lines sometime soon though.
@@jake_spence those vaccuum lines are often neglected much. Upgrading them saves the hassle from boost leaks
Before you start modding you could test with DRAGY to check improvements
I'm going to do that once the roads dry up!
Amazing video! Great detail, awesome commentary, & straight to the point. I will be walnut blasting my n54 this weekend. This vid made everything clear as day, I can’t thank you enough. I couldn’t hit the subscribe button any faster Lol . Keep up the great work brotha !!
Hi mate thanks for your videos
I have a 750 li 09 has excessive carbon build up on plugs n bad fuel smell when oil drained
Do you need to remove the spark plugs while doing it or no?
What about the rubber&metal piece inside the gun? Do you leave that in??
Also when I pull the trigger all my pressure goes into the hopper and very little out of the extension
I'll stick to my N52 port injection then, thanks :)
I have an 09 335i with 50,000 miles , should I Walnut blast?
It's better to do it before it gets as bad as mine, but I wouldn't worry too much about it. Definitely get it done by 75k.
@@jake_spence Awesome, thanks!
You need to pan more slowly with that camera. Its refresh rate is way too slow.
Current index of injectors is 12.
I suppose your 3D printed inlet guide is holding up well as some have commented theirs is not.
Well done job.
Yeah, I need a new camera and some steadier hands. The inlet piece is holding up great! I've used it a handful of times now, but I am careful with it...
Are the brass adapter fittings for the media blaster nozzle available elsewhere ? The link you listed in no longer good.
Dude i just love a clean engine bay ...u are not a car guy if your engine bay looks all oily and dirty 🤮🤮🤮 great work on the car 👍👍
So how many catch cans does one need on these direct injection engines? Think 10 will do it because one made it worse...hahahaha!
The only reason I bought my wife an 08 port injected 530i was because of that dam direct injection. So many sport cars that I would like to buy but wont cause of direct injection.
Yeah, direct injection definitely has it's pros, but this is a big con.
seems like the charge pipe was the hardest part so why cut it out???? how did you get it out???
Good job having that catch can on but why did the carbon still built up on the valaves while having the catch can installed.
Im at 135K miles on my 2012 528i. You think it will make a difference?
Hey amigo the link to the blasting wand and adapter is dead any help
would be greatly appreciated great work btw!
Nut blastin'
Nuts everywhere.
Is this issue with only M or is it with all E90’s? I have an 2008 328i with 128k miles that I just bought. No mods at all
Only the 335i I believe.
Is this carbon / oil crap also in the intake runners, intercooler and everywhere else ?
Ciao, ho una bmw 318d N47 ho smontato il collettore d'aspirazione e le valvole sono sporche come le tue, molto olio indurito, devo usare CRC?
isn't the purpose of the oil catch can to NOT introduce oil / blowback into the motor? Those intake ports looked pretty wet /oily do you thing that burger catch can even does anything?
Yes, that's the point. These cars have two parts to the PCV system, a high side and a low side. This catch can is installed on only one of the two sides, so it only catches vapors while in boost, not while just cruising.
Great video, super informative! First of your vids I’ve watched and I know for sure I’ll be checking a few others out and see what I can learn!
Thanks George! I'm glad you found it helpful. Lots of other videos on my channel that I think you'll enjoy. More coming soon!
Delete the egr valve nonsense and you will solve your problem all the way ;)
Those valves were pretty nasty lol. Those look as bad as a buddy’s did. His number 3 cylinder was completely shut on one of the intake valves. The carbon build was awful. It was so bad it was misfiring lmao
Lol, it was crazy!
Bro can you literally do this to mine my engine is misfiring and the shop I took it to said they didn’t believe in walnut blasting. They want me to replace valves and if the heads needed it to replace them. Quoted me at $2k or more
Find a different shop lol.
I purchased the kit now I got purchase atleast a 20 gallon compressor lol
I am beginning a 335i build right now as well in England. Subbed so I can tag along and Compare!
