Normal person: *fixes it*
Rob Dahm: “hey want to know what would be funny? Using it to crush grapes”
Man im taking a shit at 23:00 a clock mum asking wtf you laughing at
Couldn't do that with a piston engine
@@caseyfellers2316 the piston just gonna throw away that grapes... what a waste
Well what else do you do once you clean a rotary as a child no offense
Well he can now sell it as a $500 food processor
We have a strong contender for this year's Oscar in best acting, I see.
I am a method actor. I slept in a field of grapevines for a month while preparing for this role. 😂
tbf he recived a sponsor from it
If you take out all the pedophiles rob jumps up to top 3 actors at least
So cringy but i died 😂
but, why?
The intro is actually gold i laughed too hard😂😂😂
Twas twas eteheh
💙💙❤💙❤
You took the words out my mouth 😂😂😂
im off to buy a bulk lot of welchs 100% grape juice right now!!
I feel like grape-drank all of the sudden...
Welch sponsor?
That four rotor should be completed in no time
Wait until you see what I’m negotiating with that car. 😇 but yes Welch’s made it possible to restore the 3 rotor without taking away from the 4
@2Lysergic4Insurgent7 I believe the word you're looking for is M I G N I G H T P U R P L E.
Rob Dahm glad you got a sponsor(with terms you like) to help daddy Dahm.
@@Whitestorm2 Probably "midnight" actually
@@RobDahm Still waiting to see what you negotiated ;)
So bad, its great
Hahaha thank you 😊
The best sponsor I've seen yet hands down💯💯keep doing yo thang
Yes indeed
@Bicc OG ? really
@Bicc OG Jesus christ, what does that have to do with Rob and his love for rotary power and grape juice? Nothing, exactly, just because a black person comments on something doesn't mean they share the same views as you. Do us all a favor and leave the race shit behind and enjoy the excellent content that Rob and Jared have made for the viewers enjoyment.
@Bicc OG you're weird 🤨
Bicc OG WE GOT ONE OF THOSE FOLKS PEOPLE
Why are the ports blurred? Is it a JDM porn joke or is it to keep the porting grind pattern secret?
If I recall correctly, it's both.
It’s hiding Ables special porting, did the same while building the motor
@@cityt8 thanks! I've seen it before in his other videos but the only answer I found in the comments was just about Japanese porn haha. I figured it was this
I think it's purely a joke, you can see the ports in many other shots other than the blurred ones
@@cityt8 yea but why ? it is illegal in US ? BTW in 27:45 everyone can see it
Only rob would turn such a negative into a cheesy grape juice commercial 😂 this is why we love this channel always bringing out the best from the worst possible situations
If the engine was ran with a turbo and turbo piping was welded without flowing gas through it maybe some slag broke loose from the inside or some pieces of the turbo.
This is actually a good thought. Happens alot when you dont back purge pipes while fabricating
big brained as fuck. sounds like the most probable explanation.
m8onethousand big brained he reckons
And not running a air filter with a huge air pump (turbo) sucking in small rocks exc. a good filter doesn’t even restrict airflow! UA-cam video needs to see the compressor wheel spinning, overrides saving the equipment. Rob seams to have other professionals do the work (I do not hate him at all for this) so I would not throw the welder under the bus so fast. I’m also a fabricator so I may be bias some😂.
Darien Charlton does the back purge prevent slag inside the pipe when welding? Generally curious?
Engine breaks and tears it apart
Rob Dahm-"Thats alot of damage"
Next 3 rotor video- Special guest Phil Swift fixes all the damage on the 3 rotor with flex seal.
I might do this to my coolant jacket in my 12A!
For everyone wondering why he said mad max not mad mike, there is also another guy in New Zealand who has a high power 4 rotor fd rx7 called ‘mad max’
Cool. I was about to pull Rob up on that one! ;)
Yip and madmax is a beautiful piece of engineering
Never heard of this madmax before lol i think thats a joke and he fucked up
I love how they’re obviously staring at the script the entire time, that just adds to how utterly hilarious this whole thing is
Stfu already
@@glock1inthetop45 This guy tryhards for top comment every video.
Rusty P3nis Yep
@@Uizzj but these are fun asf comments
@@Uizzj i cant even watch this video yet im saving it for school to watch next day FUCK
Thanks for making comprehensive rotary content!
Drinks the grape juice.
Pushes RX-7 1/8 inch.
Happy with a thumbs up.
not even mad about having to watch the intro ad, was actually funny.
they need to air that welches commercial jaja
You need to ask Cleetus McFarland about oil pressure 😂😂
Matt 68 do it for dale
Top Tip from Rob ''if you don't remove all the bolts, the part doesn't remove!'' 😂😂😂
What happened to that 77' celica you had in the garage its like my fave car and you never mentioned it
Has a super desirable 3 rotor engine... Uses it to crush grapes.
The engine was fucked mate..
Getting a three rotor is was easier than getting a four rotor.
@@brien1254 Does that mean a three rotor is not super desirable? I don't get it.
@@shona5512 I know. I'm a massive Dahm fan and a Patreon of his. It's just a joke.
What's desirable about an Engine type so unreliable??
Best commercial ever!
FINALLY SOME 3 ROTOR CONTENT ❤️😤❤️❤️
Never seen a rotary engine up close and personal, but been a gear head my whole life. Great stuff. Thanks!!
4:06 - 4:40 Usual deep mechanical understanding being conveyed, thank you I think this explains why I can’t remove my fender.
Who knew y'all had such mad thespian skills, I could feel the refreshment all the way over in the land of Shakespeare
I love the sponsorship I'm gonna go get a bottle of Welch's ™ 100% grape juice™
Best ad skit I've ever seen in my entire life, thank you Rob and Jared.
Well guys, have you heard of the TURBOSLICE?
Good times
Heard of a sledge-o-matic, now we have the rotor-o-matic. if was a running model how far would the grape juice shoot out at the audience?
2019 and people still hiding there ports smh.
If you're tired of replacing gaskets every time you take something apart when it comes to the your engine buy this stuff called halimar .you put it on both sides of the gasket it never fully dries so it always has a tacky surface just wipe it off carb cleaner and reapply it. it's not like RTV you do it super thin layer
Okey, that intro was really f*cking epic! 🤣🤣🤣🤣🤣🤣 Well done papa Rob!
Daddy Dahm's E85 100% grape fuel
Dont you mean G40 grape fuel
In this video, Rob does a Welch plug.
if there is only one thing i know about rotary engine, all seals, bearings, and gaskets should be replaced during a rebuild. no skimping. fresh or bust.
Intro is hilarious. I am a straight 6 BMW enthusiast and I many never go rotary but been following for almost 2 years now every video.... This is y. not many youtubers can keep me interested for too long but Rob u are funny and honest. Keep up the good work..
Rob does the best sponsored adverts. They're so hilariously bad that it's enjoyable to watch.
Man this was poorly built look at all the rust in the apex seals and rotor iron looks like it has been leaking coolant as soon as it was started for the first time. no wonder why the apex seals are stuck not because of a lean condition or smashing in to the housing it's because the rotors have been bathed in coolant from the get go.
Not to mention that the Iron porting is flawed Because why would there be a gouge in the rotor,iron and housing, that indicates to me that the porting is too aggressive or not measured properly allowing one of the corners of the apex seal to fall out.
i thought the exact same thing.
Rob Dahm: We have to censor out the ports
Also Rob Dahm: films the rotor and shows the port
NagizaH8 that’s the exhaust port
Why does he censor them?
@@brycedale1712 It's not a Renesis motor, those whore the intekes.
The first time was around 27:45 and the second was at 30:00
Welch’s is such an honestly good company with good products ! I would be honoured to be sponsored by them
Very informative video, Rob! Good luck with the rebuild. Thanks again!! Zoom-Zoom!
love you rob dahm
26:21 ...I mean I get that theres secrets in how you port a rotary, but are rotaries REALLY still relevant to keep hiding things like that? You can barely find decent builders anymore and people STILL squander secrets to the grave.. I hope Abel is training someone to replace him lol doesn't look like your gonna learn it from anywhere else.
Lots of niche repair folks do this kind of thing. It's upsetting. These people will take their techniques to the grave and their art will die with them simply because they do not share. This type of thing happens in Typewriter repair, film camera repair, and many other mechanical systems lost to time.
There were plenty of shots of the port if you really wanted to steal it
I don't usually comment on UA-cam videos but I gotta hand it to you, I have never seen a UA-cam channel put so much effort toward your sponsored ads! You actually make it entertaining to watch! Also I want to mention the ads are actually relevant to stuff we might actually buy, not some wierd game. Thank you. You seem like a genuine guy.
I don't believe I've ever had the sudden craving for a nice cold glass of welchs grape juice ever in my life as I'm having right at this exact moment

You sure do owe alot of 10 bucks...
I ALWAYS skip forward past the opening promotion bit whenever I see it on a YT video (usually some video game of some sort!!), but this is the first time I've ever sat and watched it all the way through..... and enjoyed it!!! Haha! Unfortunately, we don't get 'Welchs' grape juice over here in Ireland - so I can't rush out and buy any, but still by far the best promo I've ever seen anyway! ;)
Well I guess the one good thing about rotary engines is that you have an endless supply of content because something is always broken and or still be built 5 years later
I got a list, here's the order of my list that it's in;
It goes, Chevy, 2JZ, Compact and Buggy
Rotary from Mazda, Jetta, corvette, NOS and then me 😂
Eminem
Respect
Mad Max is from Australia, Mad Mike drives the red bull rotary drift beasts and is from NZ bud 😉
rosscosr1 surprised you didn't state that he drives multiple rotary cars, some with 1,200 hp.....
Making a drift lambo now too doubt he will ditch the v10 tho
He's actually talking about "Mad" Max Flower from NZ,who has a big single turbo quad rotor rx7. Search "AdrenalinR presents: Madmax 26B Turbo Skid" for the video of his burnout.
rosscosr1 Facebook search madmax 26b turbo rx7
Its in new zealand
Its completely sick
John Strong thanks 👍
One of the best videos I've seen in awhile. All the "correct" terminology and information is a plus! Lol, now I know how to tear down a rotor engine and remove all the thingys and stuff. I've never owned a rotor engine, so I'll have to go get one now so I can work on it. Thanks!
35 minute Rob Dahm Video?!?! thanks for making a shit day slightly less shit :)
Lmao, that intro.
I HATE GRAPE JUICE!....But now I just might have to try some.
There's always wine, or champagne, hell even some vodka is made from grapes😏
@@brien1254I don't drink any alcohol, have never had a craving for it.
Daddy Dahm should paint the 3 rotor Purple in honor of Welch's helping out !! Thank you Welch's!! Now where's my grape jelly sponsorship for my 92 300ZX 😆🙂!!? no for real I need monetary help ..
Thank you for being so open and complete about these engines, what a piece of art! I learn so much by watching, thank you!
"Mad" Mike Whiddett is from New Zealand and runs the quad rotor RX8.
not to mention quad rotor rx-7 and a double turbo quad rotor mx-5
What's your PO box? I have a cheap 1/2in electric impact wrench that works really well I'll send you if you want. Chicago Tool from harbor freight. Haven't used it in a few yrs.
Do you have a table also?,so he don't have to put things on the floor!😆
To anyone going into the headache of tearing apart a rotory engine a few boxes of Ziplock bags, a Sharpie marker and a Hanes manual are your best friends.
I have a tone of BMW’s a couple M cars and a few others. That’s how you get nice things fix it up and don’t waste money. I buy all my cars wrecked and fix them. Used and get creative parts saves you $$$$$. Glad you practice conservation like that. Enjoy your videos Rob.
Uhg yes 35 min of nothing but Dahm
10:14 I spy BMW 2002 in that port arrangement :P
Rob do Yourself a favourite and get tables and workbenches all around the walls to put bolts and parts in cardboard templates scemes and boxes😉
Precision is surpreme on those high performance engines!
I have never bought or drank Welch's grape juice before in my life. But I am going to go get some right now. Best sponsor intro ever!
I've been watching for almost a year and never noticed him blur the port before. Did I miss something as to why he is hiding it?
Nvrmnd. Finished reading comments. It's Able's special port shape
joe schmoe it’s a Japanese porn joke. They can show a wiener and a vag unblurred but as soon as they touch or penetrate they have to blur it. Nobody cares about secret port shapes anymore
At 26:00 why are you blurring the port? I’m assuming that’s proprietary to able or whoever you worked with on the engine?
Japanese porn reference
Yeah it's Abel's custom port and he doesn't want it spread around since he probably went through a lot of testing to find a design that works as well as his.
@@NiSE_Rafter Those ports don't look good where you can see them unblurred.
Can i just watch your Welch's 100% grape juice commercial over and over and over again by itself. Please??
I almost died pulling the rear flywheel nut on my rx8 that big bastard is torqued with the power of the sun
Rotary are sealed by paper clips, bobby pins, and chewing gum?
lotsa things are. you dont wanna know tho
How did you get hooked up with Welches? Seems like a odd connection 🤔...but I like it.
this is great sponsor involvement, I'll have to go get a bottle for this 😂😂
For all of you confused Mad Mike Whiddett is a drifter sponsored by Red Bull. MADMAX the person Rob was talking about in the video is a guy with a gorgeous single turbo 26B RX7. They are different people.
I don't understand why does he blur the port job?
Trade secret maybe?
Yeah most likely unique port job from Abel that he doesn't share with the public.
it's "mad mike" from new zealand rob he's a pro drifter not mad max that's a movie character hehehe
lol so funny
There is a guy with a black 4 rotor rx7 here in New Zealand, called Mad Max. Search it on UA-cam, there's a video of him doing a burnout and it catching on fire.
@@killerjaysr6714 i stand corrected sorry rob sorry chat there is a guy called madmax with a sick af 4 rotor in new zealand ua-cam.com/video/IUxBWzVS_hs/v-deo.html thank you @killerjays R
Lol the intro. Good thing is I have a food processor and didn't even know it. I just gotta dig it out of the building. And to top it off it's the premium model. A Cosmo !
Y’all Wild, don’t ever change! 😂
why are the ports blurred im so confused 😂
Some rotary builders like to keep their port work a secret... for whatever odd reason. There is literally no mystical magic behind it.
There is even an engineering picture, with measurements, on how the portshape determines the opening, duration, and closing of the port to determine what the powerband is going to be. It also includes measurements on bridge ports, as well as measurements for scalloped rotor for even more port timing. And this is just for the intake ports. The exhaust ports are easy and have simple measurements on matching them with the intake ports.
Its not rocket science anymore like it was in the 80's and 90's.
cant leak boost when your pushing 0 psi
Watched the whole thing haha so happy you’re making consistent vids again!
I like how he just turned the rain forrest cafe glass around so you could only see the back of the label lmao
Why is the port blurred out?
GezzyJ its like how ls guys are about their cam specs he wants to keep it secret
its hiding the port pattern so no one uses it cause its a special port grind kinda like how people do street ports where they grind it down to make it bigger he doesnt want others to have it i guess
@@nyc5oh961 ahh I see so it's an Able special.
A lot of rotary engine builders keep their porting shapes a secret so that someone else can't just copy them. I'd assume Abel didn't want him showing his work/secrets.
That was the stupidest ad/intro I've ever seen in my entire life, and I've been watching your content for quite a while now....
10/10 lmao I'm in tears while drinking a nice cool refreshing glass of welch's grape juice. So delicious!
@ 8:53 "That's not where i came from, & that's not what my UA-cam is about"
RESPECT!
the only youtube plug ive ever enjoyed hahaha
pretty sure its mad mike, not mad max. he is a kiwi and wouldnt appreciate the aussie reference....
It's MADMAX. Mad Mike is a different person. Both of them have 4 rotors.
@@blindy9897 mad mike and PPRE also have a 6rotor and is more known than madmax....
Westy W Facebook search madmax 26b turbo rx7
Its in new zealand
And mad mike is only sponsored by ppre, he isn't apart of the company
Ppre are the ones that built robs 4 rotor eccentric shaft
@@John.strong PPRE built an RX3 with a 6rotor like 6/7 years ago, your point being???
What is with the blurring or that port or whatever?
The intake port
@@ibingly Right, but why was it blurred......weird?
@@GSXR13K Because the engine builder didnt want to let their secrets out. Aka they are babies
secret porting job
Chris Nelsen baby for not wanting his design that makes him money to be leaked? Whew imagine having a good concept and giving someone else the patent to take money out of your pocket.
Lol the intro nobody was asking for but everyone wanted 😂
I knew about the apex seals, but it was another thing to see it explained in the context of a failure. This was super informative.
Taking inspiration from Scuderia Ferrari with the promo?
Oh and it's Mad Mike Whiddett not Max!
No, its MADMAX. Mad Mike Whiddett is a completely different person. Both of them have 4 rotors.
Rotary breaks even before start up, LS1 still runs. #justrotarythings
Hahaha. Damn intro to Welch's grape is killing me!!!! Hahahah. Musical selection on point. Why is the 80s electronic music fitting for the montage so well....I dont know it just does.
I was dying when you dropped that corner seal into the motor, the ad was great too. Congrats, sounds like that was a pretty _juicy_ sponsorship
Ffs don't refer to Australia when you mean NZ.
sorry but why keep blurring the piece on the engine
secret port shape.
@@nssherlock4547 Maybe the secret port shape is a dick? And has to blur it for UA-cam.
I’m not sure why you’re sponsored by grape juice, but that was the best ad I’ve ever seen.
A1 acting rob! 😍🔥
I dont think I could ever love a rotary engine.. more than Welchs grape juice.
there's nothing I like more than a Rob Dahm video and nice cold glass of grape juice
What he said about taking all the bolts out, how to, and what the bolts will look like had me laughing but it's true
23:14, I literally spit my beer all over my car when I seen and heard that. I haven't watched this video since it was posted, I decided to show a friend who actually has a 3 rotor FD so he could see how to (or not to if you're a pro) first check apex seals and disassemble the engine.
