I was the one who suggested walnut blasting awhile ago when you were dismantling part of your engine . I had a real positive experience with walnut blasting my direct injection Audi S5 4.2 litre . I'm glad you like it. I also suggested dry ice to clean your engine etc . You really should look into it . It would take your engine cleaning to better than factory new .
I didn't know you bought the whole kit, that's great. You'll definitely notice an overall improvement. I'm severely overdue myself and it's on mt maintenance to do list.
Did this on my gti a couple weeks ago, 97k miles so about 37k overdue lol. Such a huge difference after, economy went back up about 10-15%. Butt dyno much happier too.
Oh hey fun fact, you can chuck a boatload of zip-ties in a cordless drill (use one or two around the cluster to keep them from bending out all over the place) and use them like a rotating scraper to get the chonky bits removed first. I'm surprised Adam didn't think of that, that's straight up Chair Force Engineering. :D
Nice video! I just did a big walnut blasting series on my channel with dyno results before and after. Someone commented with a Maserati asking so I'm going to show him your video! Cleaned my EcoBoost Mustang that I've run over 180 closed course days, 130,000 miles. It was a lot worse than yours. We gained back over 20 peak HP but the dyno curve was crazy to see how much longer and stronger it would pull in the high revs.
Great results. I would recommend a high CFM compressor at least 14.5 cfm (£260/$356) and you run for much longer on each valve to get near perfect results. You can use the adapters to help raise the height/angle of blasting.
Thanks Dan, I’ll be replacing 3 failed knock sensors so the intake is coming off . Under “while I’m in there “ heading I’ll be powder coating the intakes covers and now I’ll have a look at the valves on my 360. It’s only got 19k but if the valves are caked up I’ll do this as well while I’m waiting on the powder coat. 👍
While you're in their Jim I'm not sure if the 360s use the same valve vaerator (spelling) system for the variable valve timing as the Ferrari f430 but if it does chances are they could be leaking internally. If they are you'll notice oil around the pigtails of the connectors where they come out of the valve cover. In order to disconnect those clips without breaking them you have to unbolt it from the valve cover there is a tine on each side of the connector that you have to lift up usually a couple of pick tools can help you do this or some tiny screwdrivers one on each side. The 430s are notorious for leaking internally and if they fail the car will run not so well. It won't damage the engine but they will run poorly. They are difficult to get to and it was a known issue with Ferrari that these failed prematurely and they redesigned them at one point but the redesign may not be any better just did it on my Ferrari f430. They are very expensive and there's four of them. Fortunately the Maserati part is a Ferrari part and it will work as well the only difference is the pigtail coming off of the unit is a little bit longer. Just a heads up of something to keep in mind while getting underneath the valve cover as well as doing gaskets.
@@johningle6363 thank you John , I’ll certainly have look once I get the intakes off . Not looking forward to the job and waiting now for the knock sensors to arrive . At least I know Dan has suffered the experience as well .
You should try the dry-ice cleaner that Tavarish used. Same idea as your walnut sprayer, except you use crushed dry ice instead of the walnuts, and when your done, the dry ice evaporates leaving nothing behind. (He used it to clean his wheels, engine, and paint...) Also with dry ice, you could probably do it with the valves open, and clean off the valve seats also.....
Because the 458 is a direct-injection engine and the valves do not touch the fuel. That gunk is the PCV crankcase blow-by getting recirculated. Pay attention! He told you this in the video.
That's not the combustion chamber, that's the back of the intake valves in the heads. No Shell fuel ever gets there on a direct injection engine. If it did it would have looked much cleaner.
Those oil catch cans do work, as long as it has the bronze filter in it. I put one on my truck. I was amazed first that it really worked and second at the amount of oil, water vapor , sludge it captured. But of course the avg consumer would never empty them so the don't use them from the factory. Idk i think avoiding having my intake and valves sludged up is worth the extra work. .
Great video. Just curious what does Ferrari charge for that that cleaning service? Did the walnut cleaning machine supply all the suction and cleaning power or is there something else needed. like a shop vac or air compressor? Also did the machine cone with enough media to easily complete the job or did you need to acquire more media. Is the media available to you locally? Maybe if you get enough response or do this again with one of your friends, maybe show the hook up in more detail and a list of recommended tools needed.
Little confused on sequence between the oil leak a couple of weeks ago and the engine torn down walnut blasting. Walnut blasting before or after the oil leak?
I "Walnut Blasted" my BMW 760 V12, it was like night & day. Better performance & misfires disappeared. I gained 25 HP as per dyno tests and my V12 runs smoother. Most of my know it friends never heard of Carbon build up valves and they said just blow it out which don't work.
Looks great..... historically, the only Chinook helicopter that ever crashed was after a walnut cleaning, a larger piece of walnut was lodged in the gears that caused propeller rotation to skip, causing the rear propeller to make contact with main propellers, resulting in blades breaking thus leading to crash.... "The More You Know"........ It doesn't look like you will have that problem....looks great
That 1982 crash in Mannheim, Germany was due to walnut debris in the oil passages of the transmission-bearing failure. They routinely used walnut debris cleaning as a normal process, but the original procedure called for cleaning the oil tube/passages/journals with 3000lb air pressure. They had changed the procedure due to an OSHA Inspector investigating the shop at the Corpus Christi depot had cited them for that pressure safety. The army changed their procedures due to that. The subsequent stand-down post accident showed numerous transmissions with some walnut debris inside them. Cited from Ft. Rucker investigation team.
Overall, it’s been a ton of work. Nicely done with the walnut blasting. The outcome may not have been like new but any outcome beat what was in there. It looked like the valves had Black Lung Disease.
ok, another tip on the valves your working on pour some fuel into the intake & let it soak 'rehydrating the carbon' its then much easier to wipe off & suck up using a small vacuum cleaner, regarding the walnut left in the intake track, you need to be very careful as it could fowl the closing of each valve where walnut is left behind.. I'd suggest using a small pick to move it& then hoover it up so its clean/free of any foreign debris..
@JimC481 , the newer motors spray directly into the cylinders , bypass the intake valve . Not getting washed with gas anymore . Positive crankcase ventilation system , is directing the air back into the engine. It has oil residue from the engine . That form carbon on the valves . Causing this problem , to clean them .
Certainly the Shell and other company ads touting clean valves are misleading for direct injection engines. This problem is why Toyota and others went to dual injection. Port and direct injection for each cylinder. While more complex it gives the power and control of direct injection with the valve cleaning and reliability of port injection. Chemical "solutions" like Seafoam also won't clean this type of baked on carbon.
Totally unnecessary , Gdi cleaner would do the job . Without disassembly . Made by CRC , I did use it , made a huge difference . Warm up engine , spray in the intake , wait an hour . Take for a drive , to blow out the carbon . Note , if you have Map sensors , don't spray through them . Find a vacuum port after them . This stuff , does clean the turbo as well .
Dan, I am extremely disappointed in the fact that both you and Adam went an entire video without once cracking the obvious joke about "nut-blasting". Are you trying to go all mature on us? Just because you have a kid doesn't make you a grown-up!

Well, dry ice for next time I suppose...
@@normalguysupercar what could possibly go wrong? :D
Dan you give a real look at the maintenance and upkeep of a very expensive cars. Bravo Zulu ✌️
Thank you
I love walnut shell. I use it in my tumbler to clean my ammo casings and it does a wonderful job. Way to go Dan!
Yeah I've heard of uses like that as well.
I heard that Adam…never gets old!
Lol
So, you gave your 458 a colonoscopy-like procedure down the intake. The valves were really junked up! They look nice and clean now. Good job!
Intake would be your esophagus,, where as the exhaust would be colon.
@@PFLEONARDI0906 yea, but esophagus doesn’t have a similar ”dirty” sounding connotation, lol
LOL! Great analogy.
Thanks again guys....
You're welcome
I didn't know you bought the whole kit, that's great. You'll definitely notice an overall improvement. I'm severely overdue myself and it's on mt maintenance to do list.
You're welcome to borrow the kit when you do.

Yeah it feels more responsive. I wish I would have dynoed it before and after.

congratulations that is a great result 🎉👍
Thank you!
I didn’t know Ron Jeremy was into super car maintenance 😹
Many puns…pistons, piston rods, lubes, blower anything more…demonetization
Lol!
Great results. I would recommend a high CFM compressor at least 14.5 cfm (£260/$356) and you run for much longer on each valve to get near perfect results. You can use the adapters to help raise the height/angle of blasting.
Yeah for sure a bigger compressor would help
Hey Dan, would this walnut blasting job be nearly mission impossible on a 458 Spider then since the hardtop is in the way? Hmm
Yeah I was thinking about that... You'd likely have to either drop the engine or pull the entire top assembly. Yikes.
Thanks Dan, I’ll be replacing 3 failed knock sensors so the intake is coming off . Under “while I’m in there “ heading I’ll be powder coating the intakes covers and now I’ll have a look at the valves on my 360.

Yeah might as well look and if they are dirty, the extra effort to clean them was not terrible compared to the rest of the job

Yeah, I considered that but it looks a bit more complicated and different equipment.
So how come the Shell Premium Nitro ain't keeping the combustion chambers clean?
Because the 458 is a direct-injection engine and the valves do not touch the fuel. That gunk is the PCV crankcase blow-by getting recirculated. Pay attention! He told you this in the video.
That's not the combustion chamber, that's the back of the intake valves in the heads. No Shell fuel ever gets there on a direct injection engine. If it did it would have looked much cleaner.
Hi, how long does it take for all this fix ? thank you
Depends on who's going it
How about dry ice blasting
Yeah, try buying a whole bucket of dry ice and containing it while you blast. 🙄
Those oil catch cans do work, as long as it has the bronze filter in it.
I put one on my truck. I was amazed first that it really worked and second at the amount of oil, water vapor , sludge it captured.
But of course the avg consumer would never empty them so the don't use them from the factory.
Idk i think avoiding having my intake and valves sludged up is worth the extra work. .
I agree
Great stuff.
Do you know if dry ice will do the same job?
I don't know but supposedly
Dan, did you notice a difference that made the effort worth it afterwards?
Yes
Great video. Just curious what does Ferrari charge for that that cleaning service? Did the walnut cleaning machine supply all the suction and cleaning power or is there something else needed. like a shop vac or air compressor?

You need an air compressor. The kit comes with enough media.
BMW has an 80K service interval for walnut blasting. Call the BMW service department and ask for a quote.
That walnut blaster thing looks interesting, but idk i think the bg intake cleaner and brush method gives a better result.
Well the good news is there are lots of options to clean intake valves. Many seem effective
why does NO one use soda blasting for this procedure ?
I don't know
Little confused on sequence between the oil leak a couple of weeks ago and the engine torn down walnut blasting. Walnut blasting before or after the oil leak?
Before. Edited videos are a week or 2 behind.

That's awesome to hear. I wish I had Dyno tested it before and after, that would be fascinating data
Hey Dan? How do you propose that a "dead" bug managed to "fly" into your intake??
Are there zombie flies in Texas???
Might be

Nicely done with the walnut blasting. The outcome may not have been like new but any outcome beat what was in there. It looked like the valves had Black Lung Disease.
Yeah they aren't perfect but they were certainly much much better.
Why wouldn’t you use dry ice and eliminate the risk of engine destroying walnuts?
They’re crushed walnuts, almost more of a powder so they’ll burn off very efficiently
Nicd job guys... Well nice job Dan, Adam was most of the time in the phone hahaha :pp
Lol
but said "im not so sure" about the walnuts Dan.. lol they are awesome!
They did great
ok, another tip
on the valves your working on pour some fuel into the intake & let it soak 'rehydrating the carbon' its then much easier to wipe off & suck up using a small vacuum cleaner, regarding the walnut left in the intake track, you need to be very careful as it could fowl the closing of each valve where walnut is left behind..

I thought Shell gas cleans your valves lol
It does when it is sprayed on the valves...
@JimC481 , the newer motors spray directly into the cylinders , bypass the intake valve . Not getting washed with gas anymore . Positive crankcase ventilation system , is directing the air back into the engine. It has oil residue from the engine . That form carbon on the valves . Causing this problem , to clean them .
get that carbon good!
Haha yes sir!
umm never scene that approach before
It's reasonably common
"Crushed nuts, sir??"
"No - I always drive like this!"
Lol nice

Well to be fair, most engines were not di until recent. But yes, I believe the best solution is port and direct combined
