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.

[@jake_spence]

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'.

[@philipwest6478]

When I did my walnut blast of my intakes I used the small spatula style picks from Harbor Freight to scrap with. The build up was gummy and scarping first is quicker than just blasting until it is all clean. Also there are small ports on the top of the intake ports that go up to the valves or valve cover. I had walnut media in my valve cover that I had to blow and rinsed out. There are tubes in the top of the valve cover that appear to route to the PCV. No one ever says anything about them but they need to be covered some way.

[@jake_spence]

Good to know about those little ports. I didn't think any walnut shell media would go up into there, but it's definitely possible. I also used a scraping tool to loosen up the carbon before blasting. Works great.

[@Red-Eagle]

Mannn...my 2012 Sorento needs this. Did the intake valve cleaner. Had to buy new cats. But...this.....is deff what my engine needs

I have an e50 tuned 2016 Ford F150 2.7 Ecoboost (15-17 dont have the additional port injectors like 2018 up) that I bought new in 2016 and now has 193,xxx miles. I ran an endoscope down and looked at my valves, they looked pretty bad. Going to do the walnut method, not looking forward to it as it will be far more difficult because you can't get to them standing on the ground and the ports are way down in the center of the engine. But with the mods I have it's obvious that the 9 second 40-100 is not quite what it should be and the carbon covered intake valves plus the likely clogged 193,xxx mile cats are likely choking it down. I will also be installing my new CVF CATTED DOWNPIPE. Looking forward to the results. Thanks for the video, well done.

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

[@DafLiPsid3]

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!

[@jake_spence]

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.

Hey Jake, thanks for the awesome and detailed video man. Question: as a rookie on engine knowledge, I've got the tools to get the job done but my thing is that once I break apart, how do I correctly put everything back together? or at least how do you do it? I assume you have prior BMW engine knowledge right? any feedback is appreciated.

[@anoobgamer1459]

I would say best thing is record yourself taking everything off, so when it comes time to put it back just watch your video.

[@DaChosenOne2468]

makes sense... the more miles -> more piston ring wear->more blow by->more crank case P-> more recirculating CC vapors.

Very nice video! Did you have to do any extra work to get that manifold off besides the charge pipe? I had mine done at 60k miles and it was a big difference. Now Im at 130k miles. Need to do that and my tranny fluid and filter. Have the Burger CC, JB4, and methanol injection. Starts and idles great but I feel some power drain again. Thank you!

[@jake_spence]

There is a black box that is clipped to the underside of the manifold that needs to be removed. If you pull up on the box as if you want to bend the bracket, you can push it to slid it off. It's kind of a pain, but you'll get it once you figure it out. Otherwise if you can access it with some torx bits, you can just unscrew the bracket that holds it on to the manifold. Other than that, it's pretty straightforward!

[@TheFrenchPug]

[@paulrice3902]

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!

[@jamesaddison81]

Could you use a socket and turn the crank bolt by hand as opposed to jumping the starter over?

[@jake_spence]

Yes you can.l

[@chrise202]

How many CFM and at which PSI would the gun require in order to operate efficiently?

[@a.g.pennypacker3464]

With everything so torn apart I do not want to start the engine with this remote starter button. Instead I just crank it over till the valves are closed. In older cars it was easy by just disconnecting the spark plug at the distributor. How do you disable "spark" with these new coil packs? Alternatively, on older cars you could turn the engine with a wrench but that is not easy to get to by the looks of it. I am open to suggestions.

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.

[@jake_spence]

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.

[@2052lt]

You go with those index 7 and see how it works ? i mean with the future upgrades u plan to do.

[@jake_spence]

Yeah, I'll probably try to stick with the index 7's unless I start having issues. Gonna see how far they take me!

[@Talal-Melhem]

I’m having trouble with installing the wand and brass adapter I just ordered from your link to bimmerhelp, I have the harbor freight #37025 portable blaster kit same one as you, is the brass fitting ($6) supposed to be hammered into the gun?? Also the threads on the adapter to the wand don’t seem to be the same pitch, and the silver colored wand appears crooked into the brass fitting also.

[@jake_spence]

It should be a tight fit that is held in with that set screw. See this link for more information on how it goes together: www.bimmerhelp.info/Bimmerhelp_Brass_Fitting.php

[@Talal-Melhem]

Jake Spence I ended up dremel’ing out some of the gun barrel and all is well, also the 3D printed part didn’t fit to my kubota shop vac I had from costco but I found an adapter at Home Depot for $11 that worked after cutting it down a bit www.upcitemdb.com/upc/648846002637

[@mrpabs5864]

Are there any risks from bump starting the engine? Can the engine actually start running?

[@jake_spence]

I don't believe so. Not with the intake disconnected.

[@dwightbackus]

Mines got 137k on it and idk if it's ever been done..guessing a few things in the future... wanting to do a charge pipe waterpump and thermostat just so I know them are new also

[@hyousufi]

Does the N55 also need this? Is there a certain mileage that the effects are noticeable?

[@jake_spence]

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.

[@shortdom107]

I have a cadillac cts gdi 3.6 motor have a loud idle at startup and car rides fine while driving but at idle I have a horrible cabin vibration. I already replaced the motor mounts plugs and spark plugs replaced the plugs twice last year and this year. Not sure what to do next thinking walnut blasting but, cant find a shop to do this.

[@CQBCARMINE44]

Would you recommend the new pure 600 twins from pure turbos?

[@jake_spence]

Yeah, I would trust anything from PURE. These are what I would recommend: bit.ly/2Q5MlHp
