Wow. What a difference. I loved the little "presentation is everything".
Yes it will improve the performance of your car, and no I forgot to do the removal video. Thank you for your support and comments
That’s a great video - makes it really simple and easy to follow
brilliant! I am going to try that this weekend. Thanks for sharing
For everyone wanting to know how to remove the manifold for cleaning.. There's Three steps.
1. Take pictures
2. Remove cables and hoses while taking pictures
3. Locate bolts/Nuts and remove.
Thanks
Awesome video, been wanting to do this for a while. Cheers fella.
Thanks for the video. I always thought oven cleaner could work in this situation, but glad to know it works and is safe before trying it. I think this is something overlooked by most home mechanics.
After this process try boiling it in tin bucket of water for half HR see how much more muck comes off
One of the nicest methods I've seen on youtube that doesn't involve machinery only found in an automotive machine shop or similar..
Second the concern for keeping that crud out of stormwater drain, etc,
Still nice result..
I clean storm drains, and I've seen a LOT worse in em. Mingin.
Brilliant maintenance! Got much crispier sound and much more responsive throttle and better fuel consumption! A+++++

this method totally cleaned intake manifold on my Mercedes E class 290TD, and it has a lot of carbon in it. Thx
Another stonking video from BMACVAGS, and this one rates in the 'Awesome' category.
I am not too bad with cars, but had no idea that an inlet manifold got so badly gunked up. Many thanks as always :-) .
I appreciate that :)
worked for me, after wasting too much money on throttle body cleaner and brake cleaner like other forums said. Thanks!
Glad it helped
I'm going to try this out, thanks!
Damn I had completly forgotten about mr muscle. I remember my buddy at school uset it to clean a motorbike exhaust but now I will remember to clean my own intake with it :D
alot better than the other vids using a bunson burner nice one
Well looks good to me. Very impressed. I was going to go down the bicarbonate of soda way myself, after hearing how good it clean. Still I might do this instead as it gets the same result I think.
Very HELPFUL !!! thanks
Thanks for the video. I wouldn't have thought of oven cleaner to be honest. I'll give it a go.
Fantastic!!! Thanks a lot for this short video - I was thinking, do I have to remove this manifol do clean, how I will clean it? - Now I goin to do!!! Thanks!!!
I have the same inlet on my ATD 100 engine. I’m replacing it with the BXE one. The ATD/ALH has a rubbish air flow rate, and feed more air to the inside 2 cylinders rather than an even flow rate to all cylinders.
Nice. Very simple, to the point video. Informative. Cheers! :D
Thank you for watching
Great vid!
Thanks
I did mine with 2l of gasoline then rinsed it with water. Didnt take the gum out so i tried powerful degreaser (applied several times) and just then it was somewhat cleaner.For the sake of being honest lets say it was 90% cleaner but this was as much practical as I could afford cause these cleaners doesnt come cheap. I went through two 1l bottles of heavy duty degreaser. Anyway, my advice is to do this procedure at least once in 100k kilometers and immediately after buying a used turbo diesel car. It really does wonders for fuel economy and responsiveness of the engine at low revs. Cheers and take good care of your vehicles
Thankyou for the advice 🙏, but mine is a plastic body intake manifold in VW Polo diesel 1.2 TDI, how to handle it ?
Great Video and looks very easy. How does it do on a plastic manifold?
thanks ! i like your videos
Tnx for the pressure washer tip, il clean my audi tdi manifold soon 😉
That was helpful, cheers. Would hot watter work better? Or just simply use cold watter pressure washer?
My favorite kind of engine cleaner.
Nice video. I just did the same thing with my manifold for my truck. Went to the dollar store for just that reason and bought a few cans for a few bucks. Now people say do not use oven cleaner because the lye, but really its a sand cast piece of aluminum. So really all you're doing is the same thing as the guys who prep their manifolds for a paint job. I've done this cleaning method on my other truck years ago and still my manifold holds up and is still very clean on the inside. Not saying oven cleaner kept it clean after these yours but because I cleaned the gunk and grease and maintained my truck changing the oil and using good quality fuel. The gunk grease and carbon did not stick to my manifold as oppose to one that is very dirty and sticky all that crap has a foundation to stick to. Anyway, I've done this method its easy safe as long as you're outside and gets the job done.

Thanks bud. good tips, and looks safer than the "blast furnace" vid.
Use good eye protection with oven cleaner though, in case of a splash up.
As with the jet washing. People don't realise that the water leaving the end of the hose travels at 500mpsps. More than enough to take your eye out.
hey guys, i just took my inlet manifold , on a 1999 mazda 323 (protoge) 1.6 .
it was quit challenging but at the end when i took that manifold out i held it up high as if it was the champions league cup! im not gonna say its an easy job, but its freaking worth it. i was shocked how my manifold is full of shitty sticky stuff. im getting the oven cleaner and see how it goes. cheers BMAC, your awesome!
Good job!
mate you have some strange into and outro music it sounds proper mad lol but your videos are lethal, learned a lot from them. so cheers mannnn
Nice Vid, can you use the same method on the exhaust manifold?
can you do a VW TDI egr cleaning video?
I used me muscle too, found it didn't get the really caked on carbon off, but got the loose stuff off
Great , thanks👍
Nice video!
Hi guys! I did that today,but i smashed 7-8 mothballs and dropped inside before burning it with a gas @t cleaned very easy and nice.I used old mothballs with more than 99% naphtallene.Don't recomend it for the EGR valve.The valve has a membrane and fire will destroy it.
Thankyou for the advice 🙏, but mine is a plastic body intake manifold in VW Polo diesel 1.2 TDI, how to handle it ?
Will do this for my ford diesel truck
hmmm...i wonder if this would work on headers!..i have a pressure washer maybe if i do my headers with oven cleaner and pressure washer they might get most of the carbon out!...cheers
how many kms have you done before cleaning it? btw great videos!
based in north london, edmonton
great tip!
Thank you for watching
why didn't I think of that? I've been scrubbing my intake for 2 days. Thanks
Yes that should be fine
Hello✋🏻, I want to take out the intake manifold and clean it ! I'm not mechanic . But I can learn . Anyway I have LandRover LR3 V8 4.4 and it leaks from the PCV and VVT , if i replaced the PCV does the the leak will stop?! Thank you
Well done. Much better than burning it for 1 hour.
For sure
This is mad, Ill be using engine cleaner on my oven from now on
hahahaha
I've done this a few times, helps if you bag it up and let the fumes do there thing.
To stop further deposits block the egr valve off!
Thanks buddy!
great tip....i am definitely gonna be using this method. thanks
Me to waiting for removal video! :)
Coming Soon
Hey BMAC, I don't know what oven cleaner is made out of in UK, I'm out here in US so it might be different, but here that stuff is usually made of sodium hydroxide. Aluminum is actually easily destroyed by sodium hydroxide, when they contact each other it almost immediately starts an exothermic reaction that produces hydrogen and sodium aluminate, among other things. It leaves a white powdery substance which is actually the sodium aluminate from the reaction after it wrecks the aluminum..
+lalem91 I cleaned out my inlet manifold with Mr Muscle cleaner and dried it out and did see a few white spots so painted up the manifold too make it look nice and stop anymore corrosion from happening.
michael jagger Yeah, to be honest, I would guess you're probably ok using this on something like an inlet manifold, you might just have to sand the mating surface or something, but it'll ruin cylinder heads and precision aluminum parts like that.
lalem91 No i put the manifold in a tray so i wasn't dragging the mating surface on the ground damaging it. The mating surface is fine there was no need to sand it down at all. sanded the ports and polished them up to get the remaining carbon off dried it out, new inlet gasket and its fine.
Does Mr muscle cleaner damage aluminum? I need to do this but ha e seen comments where ppl say it damages aluminum. I know ppl use it to clean turbos out aswell but maybe there referring to the turbine blades as there quite thin compared to manifold thickness. Great video anyways deffo gona bite the bullet nd get it done.
Damn.. Now that's far, I'm from Manchester lol. oh well, i guess i'll have to wait for you to buy a golf tdi so you can do the video. thanks anyway, great vids pal (Y)
Any idea where my map sensor would be? 2013 Ford Ranger 3.2.... 🤙
Smart !!
do u have to leave it to dry b4 u put it back on
Did you clean egr also with water?
u can do that for dagrex silencer
Brake dust remover works perfectly
A little note to you @BMAC VAG if you put a wd40 straw on the spray nozzel and attach a hose to that you can fill the inlet from the inside by putting tge hose inside and spraying tge oven cleaner in that way
How would you wash it out?
Same as the jet wash way you have done it buddy the straw just fills the manifold from the inside out instead of spraying it from the outside in once the ports are filled up you cant fill th manifold cos they are kinda blocked
Its litteraly the same way you have done it on here -- the only diff is fulling the manifold from the inside instead bud
Sorry for the slow reply
Will any oven cleaner work? Or should i look for an aluminium safe one or something? Appreciate the tips!!
Home bargains do an exact equivalent for a 3rd of the price mate. It’s called Dr Oven I think, it’s an orange n blue can.
If you do not have money to buy degreaser, you could use this method. Find a metal container that could fit the header, boil the header with hot water and add in laundry detergent. Watch the heavy dirt melt away.
I have never tried that way before.
Have you done a removal video? And will this increase performance?
I figured out a fairly easy way to clean the intake without all the hard work. There is a product called Heat 'n Kleen manufactured by Gold Medal Products for cleaning popcorn machine kettles which get very dirty with carbon build up. It can easily be ordered through Ace Hardware stores. I made a few gallons of solution by mixing this product up; 4 ounces per gallon of water. Put the solution and intake in a large aluminum turkey fryer pot and boiled it for 2 hours on the propane burner for the turkey fryer. The intake came out spotless.
Just about any automotive machine shop has a hot wash tank that has some kinda chemical in it that really gets these things like brand new clean in like 10 minutes. Its only like ten bucks where I live.
Oven cleaner contains sodium hydroxide, which reacts vigorously with aluminum. The reaction will produce sodium tetrahydroxoaluminate and hydrogen. In addition, it will eat the aluminum.
You are perfectly right, on the directions of use of the product says: "Do not use on self-cleaning ovens, microwave ovens, hot ovens, exterior surfaces, chrome, aluminium, zinc, copper, plastic or polished/lacquered surfaces."
Would it work on plastic intake ?
I'd definitely get a duct brush to help manually scrub it as well. But that's just me. Cheers
Aaah understood mate. I do have golf but where are you based?
Thanks man! But what if mine is plastic? (Thanks Ford). Guessing this would be very bad for it. About to do my injector seals next week so thought I'd clean the manifold too but it's just a black plastic piece that comes off with the Rocker cover. Not sure what to do with it tbh
For plastic you would have to use a degreaser that is plastic friendly
Where does the water drain to? Assume down the drain and into the river which goes into the ocean?
The caustic stuff he used is originally mined out of the ground so I suppose it will end up back there someday :)
How about a video how to take it off before you clean it?
Hi I have a 52 plate 150 gttdi with FSH +77,000 miles,causing me nothing but grief,,where the rubber hoses go in and out of the front mounted intercooler they don't seem to be as tight a fit as I would expect and where the cooler air comes out at the join from the hose there is oil leaking out onto the undertray of the car..was told these hoses can vaccum and send car into limp mode,,as mine isn't wanting to go above 3000 rpm could this be a cause,,I disconnected the m.a.f sensor and didn't make any difference,,,there are no warning lights on dash at all even when I disconnected the m.a.f sensor,,also can I use Mr Muscle to clean the turbo by spraying it down the hole where the egr pipe mounts the manifold,,some say yes and some say no,,my mpg is only about 30,,taken me years to find this car with the milage and history and I like the car but at the same time am starting to not like it at all,,,love your videos on here and they really help,, fed up with performance car specialists taking the mickey and charging the earth for work..any advice is really appreciated..
Strip yer turbo and egr valve....
....vain turbos tend to choke up with carbon and sieze .
.....am having the same problem with mine at the moment.
Keeps going into limp mode because the turbo keeps over boosting.
you could maybe clean it the same way you clean the barrel of a gun. as we all know when you fire a weapon the round proppelent aspect of the ammunition produces carbon residue which builds up in the barrel and the trigger housing. to get that clean we used to use very fine cloth that was a realtively tight fit with some strong para cord tied at its centre. and we would simply drag the cloth through the barrel which would wipe away the carbon deposits. as for the trigger houseing.. we used to use boiling hot water to wash away the grease and grime and break down any carbon. im thinking this works for manifolds too as its pretty much the same thing.
I gun/rifle barrel is straight. Not so easy with an air intake. The sludge is very thick and will dirty the rag instantly and will take a fair bit of time. I have cleaned a lot of Guns, Rifles, LSW's. The boiling water and dish soap works great for those hard to reach spots especially when an LSW has over a few thousand rounds fired through it. A bottle brush and lots of soaps/brake clean will get it all out.
In this guys case i would not let the flat side scrape over the cement. It will mark and scatch that soft alloy and could make a bad air seal.
Hot water washes it out better than cold water. Once done, let it dry before installing.
What about plastic inlet manifolds? Can this method be used as well?
Fotis Fotiou humour works best on plastic
How effective do you think boiling water would be along with carb cleaner or the like as i am currently without a jet washer...
Not sure about the water and oil mix, not something i would do.
Scrubbing with hot water after applying oven cleaner will be more effective than a cold pressure rinse
better way would to be take the part to a local machine shop. and put into a parts washer. acid tank
Cleaning is the easy part, removing it is a mission.
+emilz85 It took me 1 1/2 hours to remove my inlet from my vw golf 2.0tdi
+1 on that
Heck yea its a big fat B. I Just did my 98 saturn sl1 350000 miles I used three different kinds of cleaners just to be sure it was clean I probably wont ever be taking mine off again for the life of the vehicle
Dragging the gasket mating surface across concrete is always a good idea freaking tone spoof
What is bothering you? Why do you have to speak like that?
Nails on a chalkboard
Take it easy pal, the videos are just a guide to help people. When you go round talking like that for no real good reason, it just makes you look bad. Just saying...
you help me i help you pal
Doug Ryan love your style :-)
OM642 3.0 V6 owner, absoultely not a single code although car cant start when its cold outside and runs like crap. I got fed up with it and stayed at the shop for the entire night slowly removing parts of the engine so i can get it off, it had 1cm od clearance from gunk that was inside, i was so relived to finally find what is causing it. EGR will have to go.
I used your method 2 times but tbh it did not work that well, so i took the car shop floor cleaner and mixed it with water and sprayed on it on, i was doing 5 rounds of my method and it got everything off, god the fuel here is crap
Great result in the end. Well done
Still waiting for the Video on how to remove the Inlet Manifold. When will you be doing one?
Good cleaner! Can send me the name of chemical you used, thanks
Mr Muscle
Sorry but I do not have a car in stock at the moment. So please be patient, unless you have a golf for me to work on?.
Does this make your house/oven stink? is it harmful to use an over after baking this? ha
id put a mat down to stop the inlet manifold getting damaged from being scraped on concrete but you know its his manifold so i wouldnt complain
You say its safe to use on alluminum but it says on the can to not use it on just that?
Biggest miss here would be......oven cleaner requires heat to activate. Spray it and place in a sealed container. Put container in a really warm area, even in trunk of car, and sit for an hour. It will come out even cleaner
Oven cleaner is actually corrosive on Aluminium so i would leave it on there any longer than it should be.
Dawn dish soap and power washer
I want to do it the hard way. Im tough
Is there a way you could clean the inlet manifold without dismantling of the car??
No. Volkswagen used to do it that way, but crud was getting into the engine and breaking things.
instead of using oven cleaner, use the Wynns carb cleaner. Same method though.
I prefer the oven cleaner as it foams up and finds the creases, but you can use anything you wish.
Is it the same for gas engines? Anything that can go wrong?
Diesels tend to build up carbon more. I have pulled off intake manifolds from quite a few gas cars and they are just a little black. No real "gunk". Unless you have port injection like a N54 or other german car.
I have a bkd engine would this be ok to do on my inlet manifold? would it damage swirl flap for instance?
+bruce L I did this on the BKD engine's inlet manifold last week. it wont damage the swirl flap at all. You need to disconnect the egr valve and throttle body to do this and a new manifold gasket for safe measure
I don't suppose you made a video?
bruce L Was it you that asked me. to do one?
+michael jagger ye I but on a different video though. I want to do mine now that I've blanked the egr.
bruce L I did my manifold last week but sadly during filming my camera died so wasn't able to film it. Ill see what i can do to show you how to do it and what to take off.
Just did this with Carbon-off oven cleaner. Label says aluminum safe. Sprayed on and watched chemical reaction happen quickly. 30 seconds and done.
That's awesome.
