RAY!!! Europe Twirly!!!
Please pin this. I had trouble finding it again!
@@emmettturner9452 pinned! And oops I thought I pinned it already
He doesn’t know what he’s doing but he did sleep at a Holiday inn last njght
Hey ray do you ever useberrymans b12 cleaner? it’s awesome on dissovlving build of all kinds
Hi Ray, “clean as a whistle” comes from the age of steam rail engines. The train’s whistles were steam powered and essentially received a steam cleaning every time they were blown.
The same as...The real McCoy...was an automatic oilier on steam trains invented by a slave.
Wow, I always wondered where that saying came from. I'm 60 and never knew 😊 thank you for the little history lesson ❤
just what I was going to say.
A "whistle" is also a euphemism for a male organ, I know mine is always clean. 😂
@@johnt.848 Hope you don't use steam to clean it!
One of the best sayings I’ve ever heard was “If you’re the smartest person in the room, you’re in the wrong room”.
Always be learning.
More hybrids Ray.
It will be the norm.
🙂 Ray, when you said, "I do not know what I'm doing," I immediately said to myself, "That's like a highly skilled surgeon saying he doesn't know what he's doing while expertly setting a broken bone."
You may not have done that particular job on that particular make, but you definitely have the skills required. 🙂
Exactly.
When Ray was swirling that tube around it looked like he was doing laparoscopic surgery.
A safety hint Ray. No matter what your using as a medium-- always wear a mask. Cloth is OK for walnut blast but for those doing bead or sand blast a real respirator. You all are young but still don't breath in this stuff.
if he can breathe in Brake clean, he can handle walnuts.
@@forgetfulme1719 wouldn't surprise me if breathing in that stuff caused some of his lung issues he had
@@forgetfulme1719 ah, no. the walnut is a solid and there is some dust in it. that dust gets deep into your lungs and can get stuck and cause damage. also, if you read the can, it tells you to not breath in the brake clean.
@@Racingnut24 reckless Ray thinks he is invincible, many things he knows but not doing
@@Racingnut24 many things he knows but too lazy to follow
When I started in the Machining field 30 years ago, one of the senior Machinists(William King RIP 🙏) used to work in the railroad repair industry as well as his Father doing Steam engine repair before him. He used to always use that phrase. When I questioned him about it, he stated his father used the term to make note of how clean the steam whistles were internally when they took them off for restoration. His Dad used to say he never had to clean or re machine any steam whistles internally. He only ever had to regrind or polish the outside because the inside was steam cleaned its entire life. Henc, the "clean as a whistle" ! This was a bit of knowledge he handed down, but man, he had an absolutely limitless amount of machining knowledge. Most of which I still use today. I miss picking his brain and think about him on the regular. Now I'm the old guy and I try my damndest to share knowledge I've learned, but I'll never be as versed as he was about machining and being a all around decent person.
Toyota is the undisputed world leader in hybrid engines. They will delay the transition into any other technology as long as they can, however they can.
Toyota is smart enough to not pull all their eggs in one basket (i.e. the one-sized-fits-all EV strategy doomed to fail).
But Toyota is also dumb enough they havent be able to fix the gage cluster on my buddies 2023 corolla over 5 times and still cant fix it. Been 3 months and they cant even find a replacement car
@@nissan300zttThat is a dealership issue you are talking about. We are talking about the R&D side of Toyota.
@@mart43 The R&D side of Toyota is just as dumb as all the other manufactures. You're only fooling yourself if you think they aren't. How soon you all forgot about the floor mat issue they had and many others.
No matter how ill advised. Operating a hybrid vehicle is like trying to be half pregnant. You're fooling yourself. Go with a gasser or an EV, either way, you are back in Realityland.
Love that walnut blasting machine.
Take the 5 minutes and remove the wipers and cowling. It opens the whole engine bay and makes life soooo much easier. Also, the EGR cooler is likely completely clogged making the valve replacement moot.
Ha! Just watched the Bonus Encore and see that indeed did happen later. ;)
I was wondering why he didn't continue to the EGR cooler and beyond to accomplish said goal of clean EGR system.
Good Job! Real Mechanic!
Watching you do this cleaning with ground up walnut shells jogged my memory of an incident involving using walnut shells for cleaning and the crash of a United States Army Chinook helicopter. This illustrates the use of extreme care in the use of this stuff.
"On 11 September 1982 at an airshow in Mannheim, Germany, a U.S. Army Chinook (serial number 74-22292) carrying parachutists crashed, killing 46 people. The crash was later found to have been caused by an accumulation of ground walnut shell grit used for cleaning machinery, which blocked lubrication from reaching transmission bearings.The accident resulted in the eventual discontinuation of the use of walnut grit as a cleaning agent."
yep, use CO2
@@forgetfulme1719do you mean dry ice?
@@michaelpressman7203 yes, they use liquified Carbon dioxide, dry ice is solid form ?
@@forgetfulme1719 It is solid CO2 pellets propelled with air or nitrogen depending on the application.
@@forgetfulme1719 Yes, I think CO2 blasting would be much more suitable in that application. Looks like Ray was pretty careful to blow all the walnut husks out of the intake passages.
I have had a couple of direct injection engines and having the walnut service is a must.
Younare one of the few……..most people with those types of engines(Hyundai/Kia) don’t think about it, and the dealers/manufacturers will not offer that info….. my brother learned the hard way, and is now driving a toyota……
I completely agree about the all electric cars
Im a simple creature. I see a Rainman Ray video, i click the "Like" button.
I click the like button before watching
Pretty sure you're a racoon despite you're username
@@legionofanon Me some too. So I'm even simpler.
I make coffee then…
I search him out every day like south main…pine meadow guy is alright too; but ray is #1. Oh, watch wes work is good too.
That was a good demonstration of walnut blasting cleaning. A very nice close up inside. I love it.
I have been following you for several years; I really enjoy your content. I agree 💯 with you about the EV propaganda, it takes a tremendous amount of diesel just to haul the minerals to be prossessed into the batteries.
I'm glad Ray gets down to the granular level at his auto clinic. He is the mad scientist who teaches us all. Tips and Tricks included. Have an awesome day.
I agree with you 100% about the total EV plans. The infrastructure to generate the power required and the transmission capabilities are not there! And your comment about just relocating the pollution generators to another location is also 100% correct! Finely hearing some one else, especially with your ability to educate your listeners is fantastic, thank you. The American president and the Canadian prime minister are both deciples of the wef that has dictated to the people that by 2030 we will all be driving EV’S, It ain’t gunna happen with out a total rebuild of our electrical grid.
You are a well informed and well rounded individual, I like your approach to problem solving.
Ray...that is absolutely amazing. I have a turbo GDI engine (EcoBoost) that is notorious for carbon buildup. A local shop that I trust is quoting me something like 8 hours of labor for that same service. The engine is not suffering yet. I am considering this as a DIY project for down the road. The only issue I have is that with a transverse mounted V-6, the far 3 cylinders are most likely a pain to get to. Maybe removing the cowl would do it. So far, Ford has no answer other than induction service that they actually don't recommend for the EcoBoost. The reason is hydrocarbon-based induction services can cause the turbos to overheat and possibly lead to damage.
tip for removing those walnut grains...since the area is pretty much sealed, you can flood them out, since they float :)
Spot on with the EV rant.
Thank you for all the long hours of editing 🎉
Nicely done Ray!
Most of us like to hear you geek out on stuff. I think most of us do it to but it’s hard to find like minded folks these days. Learning and pondering the wonders of life is enjoyable. Bravo sir.
Ray it's always good to know which button to press !!!!! 😉
Have you looked into C02 blasting. Uses crushed dry Ice instead of walnut. The dry ice evaporates quickly as C02 gas, so the only thing left behind is the loosened media you cleaned off.
I WAS A BIT OF A SCEPTIC ON THE BLASTING,UNTIL I SAW THIS VIDIO (GOOD JOB I WILL OWN 1 TODAY)
Nuts.
Deez nuts
FYI people the reason to use walnut shell blasting is if a few injest into the engine they just go through without damage. Now of course you dont want a bunch of them left over but a few doesn't hurt a thing. Awesome new tool for GDI engines. Have yourself a great day Mr Raymond!!
97th! Good Thursday morning Ray and the new employees! Had my identity stolen and my computer was compromised. Had to have all the issues resolved before I could use it again. Roger in Pierre South Dakota. I’M BACK!
Howdy Roger! Welcome back.
out of confusion comes order !
And this is why I enjoy watching your video's. always learning something new from you or getting a refresh reminder of something old. Walnut blasting isn't new but rarely done, at least in my area. Great video as always, cheers :)
Put a clear hose on that walnut blaster and you’ll be getting somewhere. That thing is awesome.
I had never seen a walnut blasting. I've seen the results but never the actual procedure. I think it is very effective...Great video!
Been around since the days of carbonators. I'm sure nobody every imagined they'd make a comeback 😂
Loved it when Pinkey (or was it Perky?) "forgot to connect the bracket for the dipstick tube"! Hilarious!
Morning Ray! Hope you enjoy your day and don’t work too hard
Great video, what was the fluid in the intake at the beginning?
I agree 100% on the EV discussion, Ive been saying they wont solve the pollution issues ever since the lawmakers or whatever you wish to call them decided we should go all EV. One of my concerns was how they would deal with the 'dead' batteries once swapped out for a good battery. It took them yrs n yrs to work out how to have safe and how to recycle regular AA etc batteries. And those batteries were simply going into landfill for decades. Ever since I saw a video of some guys making a hydrogen power motor bike last year I thought this was the best way forward to help reduce our carbon footprint etc
Forgot that little plastic bracket business with its own bolt on the manifold side of the EGR tube. 😂
Amen for Snap-On tools. worked on cars since I was 16. Taught for 26 years and retired. Love my Snap-Ons.
great idea never heard of this process i am 72 and still learning with you. I've done vehicle industrial ,mining , and millwright mechanic in my life and surprising still learning things watching you.
@28:40 Time to NUT-BLAST the SECOND HOLE!
Sounds like a party in the shop... LOL
The egr and the PVC are pretty much a normal changed part in the Prius. Its a simple egr, PVC and spark plug replacement since your in there. If you drag your feet it's a 1 hour job
Morning Ray, so glad you have the walnut cleaner, have been watching other shops on U-tube shows and always impressed by the results.
We used walnut shells (called Carbo Blast) to clean gas turbine generators. We would fire the turbine at a low rpm then slowly dump a bag of blaster into the air intake. The shells would go through and if it was dark out the exhaust would rain sparks from the burning walnut bits. Rather cool.
@rainmanraysrepairs I and I'm sure many others would appreciate you doing a live with primary topic of conversation and your thoughts about how you do business compared to the rest of shops after all you've lived the life of a mechanic at dealership, retail store, and now as a owner yourself
With those clips at 7 min 30. If you push them inwards first then push the tab down, they come out really easy. It's counter-intuitive but it works.
Hey Ray. Probably should have used vacuum on the #3 as you pulled out the rag. And not the blower. I feel that would push residual walnut past the rag. Take care!!! Oh and use your thumb to cover the hole on the vacuum will give it more suction
I save time watching his videos. I watch him take things apart and then watch it in reverse, saves a ton of time.🎉
Hi Ray wife unit and boys just finished video with Prius day later it was excellent and as always you all be safe 🇺🇸🇺🇸🇺🇸🇺🇸
Fuel system cleaner. From beer and gas money aka BG 😂
Or maybe BG products are made from real beer and gasoline. 🤔
@@williamsquires3070 😂
We are just out sourcing our pollution. What a great way to put it. Ray, you are a genius. No one has put it so concisely.
If that's what you think, you don't get around in EV circles, or rather, anti-EV-mandate circles, all that much.
Because I, and many others, have known about what actually happens for at least a decade now. Way I see this is, with the pollution aspect, it's become the technological version of NIMBY. And when that happens, it always gets shoved near areas where the poor and working classes live. This is no different than landfills and power plants when I was growing up, and it'll be no different than the ULEZ-style fees and scheme taking place in New York City, where Manhattan is essentially being priced out from the poor being able to even visit the island, having a $15/day fee just to go on to the island.
As a result, people are complaining that doing so just moves the pollution into areas and boroughs where kids are, thus it is affecting their health.
ULEZ is a scheme in London, England, UK, whereby people with cars of various ages pay to go into certain zones, and can't go into some zones deemed Ultra Low Emission. ULEZ stands for Ultra Low Emission Zone, and is a scheme whereby Londoners have to pay roughly $15 USD, £12 50pence, to go into certain areas of London. An old enough car, and you can't enter some areas of London at all. For workers, this means paying £80 per week, roughly $100 USD, just to go to work. And people have been protesting this scheme for a few years now, with a group calling themselves the Blade Runners going so far as to disable and/or destroy the cameras ULEZ depends on.
And now New York City is doing the same thing here.
Thing is: carbon dioxide is not a pollutant. So there's that.
@@svenschwingel8632 : Exactly. The problem really is, when you examine the claim CO2 produces what I call the "Glass Entrapment of Heat," you find out its nothing more than pseudoscience justifying a pagan cult, where the planet is more important than the people on it.
@@isaiahwelch8066You can any where in N.Y.C. with mass transit.The state too.
@@michaelpressman7203 : I wasn't talking about mass transit, or anywhere else in the state, since the scheme in London and NYC being done, ULEZ, has to do with private car ownership and use.
Essentially, these schemes are de facto licensing schemes that are unconstitutional, since cars have been a common conveyance for the last 110 years, and this scheme in NYC essentially violates the liberty of locomotion people have with their own cars and using them.
The goal of ULEZ is to economically make car ownership and use so prohibitive that, ironically, only the rich and well-to-do can afford a car and all of the fees and bureaucratic red tape that goes along with them -- thereby forcing the poor and working class people on to mass transit, and therefore controlling the ability of the poor and working class to get around whenever they want.
This same scheme was begun in London, with the same goals and objectives I just stated. Coupled with Saddiq Khan being part of C40 Cities, this is but the foundational groundwork to push the working class and poor into "15-Minute Cities" that will be nothing more than barless prisons, given the amount and kinds of 24/7 surveillance being planned and implemented. Because anyone who doubts this doesn't get it: The ULEZ cameras are _cameras_ -- which means not only are the whereabouts of people being tracked, but these cameras will all be wired together in the same network like what London already has. (If you've ever seen Fast 6, you know exactly what kind of surveillance center the UK has.)
The PCV does leave a puddle in the intake on this gen Prius. Also the EGR cooler is likely the cause of "EGR FLOW BELOW THRESHOLD" and that needs replacement as well to make this repair effective. It could probably be blasted if the walnut is fine enough as it just gets packed 100% full of carbon. There's also a recalibration in the related TSB that supposedly reduces EGR clogging. I did mine recently and improved the mileage ~14% on average without any "Prius driving habits," so to speak.
Terrific learning video. Thank you!
Impressive speed and quality. Very handy tool.
another great tool for your shop ,excellent
It IS...... always the mass air flow sensor!!! I can't count how many times that has got me.
“Not environmentally friendly?” Nuclear power is the MOST environmentally friendly. It’s just that some people are ignorant about it and express their [SAFETY] concerns as environmental.
They been programmed to believe it
Definitely a boatload cleaner than coal or gas plants, not sure it's cleaner than solar and wind though 😂
Unfortunately between the 3 you have to make some trade offs. Nuclear generates a crap ton more energy for its footprint, but is also a lot slower to build.
@@TremaineLea Yeah, but we don’t equate “most environmentally friendly” with being “cleaner” or “most clean.” It means it isn’t as destructive to the landscape, wildlife, etc. Wind turbines kill innumerable birds, for example, which doesn’t make them dirtier or more polluting but it certainly is an environmental impact.
I should have said people express their SAFETY concerns as environmental in the OP. Oops.
Amen. Too many people are afraid of the word radiation- while eating bananas on granite countertops (both emit more ionizing radiation than a well-maintained nuclear plant). Coal fired also emits more radiation than nuclear- but the ooga booga is strong. We need nuclear fission, channelized hydroelectric (IE not big dams, but river/tidal channel generators), solar, geothermal, and finally fusion to be the primary sources of power instead of LPGas or Coal.
Thanks for showing us R2! I've never seen anyone actually do a walnut blasting procedure before. Can't wait to see you use it on a really crudded up GDI engine!
Yeah, now I want to see Threepio. 🤣
Steam train whistles are clean and germ free!! 😊
Good morning Ray 🌄 you certainly entertain my brother and educate great job bro 😎👍👍
I don't see a problem with the walnut blaster. Especially with how thoroughly Ray cleaned the intake when he finished.
That walnut blaster is really great. I remember seeing it on CSI NY where NYC Parks Dept used it to clean statues instead of sand blasting. It was really efficient in cleaning the intakes. Best of luck with your new favorite tool. And the ratchet is really a plus for those who work close quarters as well.
My Best to You, Wife Unit and the rest of the clan too.
I don’t have any experience with Prius engines either but I would be thinking about the PCV valve with all that oil in the intake. If upon inspection of said PCV valve, I found a bunch of oil (like what was found in the intake) I would suggest adding a catch can system. Just a thought.
Ray just loves showing off his wobbly bits even when they aren’t needed LOL😂
Ray, you videos are so much better since you have your own shop!
Hey Ray. That new machine is fantastic! Nice work. Looks like a great job to do too 😊
The walnut blasting was great done a fine job Ray.
An hour rainman ray video again???? I have went to automotive repair heaven!
Most of it is like watching paint dry, but still entertaining.
Better than watching grass grow
@@RainmanRaysRepairs 👍My grass grows fast with four dogs natural fertilizer.
Watch where you step!
It is good to see there are walnut blasting solutions for the DIY market , but the commenter is correct, the process can cause issues if not done with care. Your videos help instill that knowledge!
YES!!!!! Been waiting for this type of video.
Put an Oil Catch Can from the PCV to the intake inline will prevent the oil from getting back into the intake.
Excellent synopsis of the problems with total EV usage by the 2030s! In a few minutes, you cover what others take an hour to explain.
I got to get one of them machines 😂. That is so cool
Those walnuts shells did a really nice job.
Now when I start my car it smells like roasted nuts - Runs great & Mmm now smells like a roasted walnut camp out. 🙂
Ray, you're right about the power consumption. We have that same problem here due to an aging power grid.
Put it this way: Either last year or the year before, I read about a town of 50,000 people having a local trucking company wanting to convert a fleet of 30 trucks. After talking to the utility supplying power to the town, it was found that those 30 trucks would take as much power to charge as the entire town would use in one day. After finding this out because the utility said they had no ability to double their power capacity, the trucking company was unable to convert to a pure EV fleet.
That being said, Japan is one of the few nations that also has a pure electrical railroad fleet and network, AND after the Fukushima disaster, decided to de-commision all 6 of its nuclear power plants, given the efficiency of Chinese coal-fired power plants.
All of these things play into the EV debate, given Japan does not use diesel-electric railroad locomotives on its rail lines at all, unlike the US, which has tried to electrify the rail network in the past, and it has always been too expensive to build and maintain. It happened in the early 1900s, it happened in the 1960s. Electrifying railroading is too cost-prohibitive to work.
I don't know where you're getting your information about Japan shutting down "all 6 of its nuclear reactors" as they actually had 48.but it is some kind of deliberate missinformationtion coming from the anti-nuclear lobby. Even the tiniest bit of research would tell you that Japan currently has restarted. 12 reactors and has permit requests to restart 15 more. And has 2 more under construction.
As far as using Chinese coal is concerned, the vast majority of the generating power in Japan following the initial shutdowns was LNG and with the restart of existing reactors, they reduce their importation of LNG significantly.
So to summarize, Japan is not shutting down. It's 6 reactors. It is restarting a total of 27 current reactors, and Japan never used cheap Chinese coal to make up the loss of nuclear generating power after the Fukushima accident. They used LNG.
Japan shut them down for inspection. They currently have 9 reactors operating again. The majority of the people want the rest turned back on. Japan has 17 nuclear plants with 54 reactors total.
@@imrf : Then the six I heard Japan was going to de-commission were probably the ones based off the Fukushima design that is a 1970s US design, since Fukushima and Three-Mile Island are the same type of nuclear reactor.
I was told EV's were magical and are going to save our future
You are one heck of a mechanic 👍😎
Unknown number! Good Thursday morning Ray and the new employees! Had my identity stolen and my computer compromised. Was unable to use it until the issues were resolved. I’M BACK! Roger in Pierre South Dakota
They should come out with a clear vac tubes that has different holes to access different locations with one way flaps, to keep the suction power it needs to get out all the walnut media. Just an idea 😜
Is better to leave the adapter in the vacuum and put air blower in the hole and blow it much easier that way
Yellow gloves sorta makes butterfingers entertaining 😊
1982, I was on the B1-B Program in Palmdale ca. next door was Northrup and they were building the B-2, Northrup had announced a new way they developed a method to strip the paint off of the composite skins with walnuts ground up fine. Just a friendly FYI
I would have taken a few days off from working on that mustang! Lol Great video as usual! Heading to the other channel now!
R2D2 made short work of those intake runners, verry impressive how well that machine works. Verry good video Ray🤘🤘
With the nut buster you can clean off a rusty caliper slides, blast off rust before putting new rotors instead of the drill operated buffing pads that velcro on and always fall off. Yes its a very useful tool but don't blame me if the shop starts getting mice.
Cool process
Respect your opinions on electric cars Ray, and I'm far from an electric fanatic: it's currently a very flawed technology and not the panacea many think it is. But there are two flaws in the argument you provide that need addressing.
First, even if the energy efficiency were equivalent, you can get more effective environmental controls in a large facility, even a combustion plant, than you can in a bunch of little mobile combustion plants. They can just be made cleaner and better for the environment for the same amount of power generation.
Second, internal combustion engines just are not an efficient way of producing power. Off the top of my head a modern gas engine has only about 30% thermal efficiency -- 70% of the energy that goes into it is wasted, a good chunk of that as emissions. Even a coal-fired power plant, one of the most polluting, has an energy efficiency of I believe around 60%, much less wasted effort, much less byproduct in the environment.
Which pretty much means that, from an energy conservation point of view, it *would* be a net win to have a fully electric fleet. However, you are 100% correct that there are a lot of infrastructural reasons why that can't happen now and probably won't happen for a long time. There are also very ethical worries about the conflict metals that currently go into batteries. Doesn't mean it's not a goal we should approach, though, even if we never fully let go of our lovely dino-burners.
have you considered the amount of toxic chemical waste products produced throughout the mining, processing and manufacturing process of producing Li-ion batteries?
@@user-tf3ir8sc5m I have, and that's why I went to pains to note that I was talking mostly from an energy-efficiency perspective, which was the thrust of Ray's argument.
The environmental effects of rare earth mining (and the ethical implications of making heavy use of conflict metals) are another facet of the discussion entirely, though one worth having for sure.
I do agree that by definition, a 4 stroke engine can only be 25% efficient (excluding physics). It only produces power on 1 out of 4 strokes. Add to that, friction and thermal loss, and yes, it is not the most efficient engine. However; gasoline is a tremendous energy store vs. weight. Batteries aren't even in the same galaxy. Even when empty, you still have to push around a 1000 pound battery. When a gas tank is empty, it's empty.
@@robjones3818 Agreed. I just think that when you combine the production aspects of the batteries, lack of infrastructure to charge, the fact that the only change in carbon is the source; a coal fired plant vs. a tailpipe. Nuclear is the way to go on electrical production and that does not address grid distribution, charging stations, or the batteries themselves. I'm not an EV hater, I think instant torque is awesome, the tech will get better. I just don't think it is the long term solution when everything is taken into account. The gasoline based infrastructure has taken over a century to build, we don't have the resources to replace it overnight, and it wouldn't be economical to do so even if we did.....Now hybrids on the other hand; best of both worlds. Can certainly be plug-in.
A train whistle is a clean clear sound with no overtones, ergo, clean as a whistle could mean pure, or unblemished. Most trains use two tones that are clear so you can hear from a greater distance.
Train whistles do have overtones. Even a pipe organ pipe has overtones.
We used walnut shells blasted into the engines of our jets in the USAF when they were on the test stands for maintenance. Excellent cleaning medium 👍
i use walnut media in my brass cleaner/polisher
Mr Ray,
Those "holes" between the intake runners are GNDN conduits!
You are so right about the ev and hydrogen thing, I have been saying it for years but no one was listening.
Nice job! Good to see more detail of that engine bcs my Lexus ct200h has the same powertrain.
I have heard about tgese engines having egr problems. I bellief there are aftermarket catch-can-kits available.
As I watched, I kept thinking Ray would change the PCV valve when the intake manifold was off. It would’ve been very easy to get to and perhaps the oil in the intake was caused by a stuck PCV valve. If that valve has 180,000 miles on it, it should be replaced. This video was extremely interesting for Prius owners.
Woo Hoo. Ha ha e a great day Ray and wife unit and co-worker units and of course Luna unit!!
Eagerly awaiting the walnut blasting on a GDI engine... as you pointed out on the Mazda - those intake valves can get quite loaded up. Also, would love to know what that goo was in the old intake manifold. I hope you asked the owner what sort of treatment they were using, before coming to you.
Walnut blasting at one time was a method to clean gas turbine blades. It worked OK but it destroyed the non metal seals. There are chemicals that do a better job but are expensive. Walnuts will pit soft metal surface like aluminium (Gasket face). Be sure to make sure you do not inadvertantly spray the valve stem seals.
