This video will show you an easy way to clean ANY dirty (CARBON built up) on aluminum intake. Please DON'T try this on plastic intake, Injoy the video :)
Darksyne yeah worked for me! nice weight reduction too. instead of a big clunky thing i get to have a sleep slab bubbly plastic! A true race inspired mod.
Darksyne it's true, I tried it on mine and air doesn't need to pass my stupid restrictive airfilter anymore I feel a huge hp gain since the hole in my manifold sucks air straight into the engine
Hmmm I wonder which one is more damaging? An hour long barbecue burning bags of charcoal or burning a thin layer of carbon off the intake manifold? I don't know man, maybe the 2nd one?
+BMAC VAGS Be very careful using oven cleaners with cast aluminium or magnesium parts.sodium hydroxide or potassium hydroxide are very corrosive with non-ferrous metals. Oven cleaners are fine with steel.
I did mine today and somehow the flames were twice as long and white hot, I definitely wasn't prepared for how far it shoots those white hot burning carbon fragments either. 10/10
I love the sofa mechanics around here! ;)) "engine temperatures rise.. carbon burns off" /// "foot to the floor... wait 20minutes....done." /// "foot on acceleration pedal while neutral" It's not the EXHAUST manifold....
+Randy Howard can anyone help me? I have a '98 Ashley furniture couch, you know, the one with the 3.4 liter.. there's always this loud creak from the front passenger side. especially when I sit back down from getting a beer, or hit a pot hole. usual stuff. I've checked over the suspension parts. springs and shit, but I can't find the source of the problem.. really in a pickle here.
+RRtradestar You just need some more unicorn farts. That'll do it. Oh and don't forget to check your blinker fluid, that always gets people. And they wonder why they're losing on the low end.
That’s exactly how I clean the exhaust on two stroke dirt bikes that are all clogged up with oil didn’t think to try this though for a carbon filled intake. Thanks for posting this
haha yes.... cheap intakes nowdays..... iv seen a lot of them blow up after some higher milage ... especialy in BMW m57 and n57 engines (first generation m57 had casted intakes the last forever)
Why bother cleaning them? the idea of plastic is being CHEAP... Compared to Magnesium and Aluminum Manifolds you can buy a complete new Plastic Manifold and call it a day.
the reason they use COMPOSITE intake manifolds these days isn't because it's cheaper. they use it because plastic can't be heated up as easily as a metal like aluminum or steel. this allows the intake charge temps to be lower when the motor is heat soaked or at operating temp. the lower the intake air temp, the more ignition timing the computer will advance.
Did similar with a choked up silencer from a 2 stroke engine, arranged to extract air from one end with torch at other end. After a while it glowed like a giant chrome cigar, turned the torch off, it kept burning for about 40 minutes. Handful of pink ash at end, was about half its original weight!
You realize that's exactly how a forge works yeah? That is hot AF there. Aluminum castings are not really made for that. If they were, they'd use them for exhaust manifolds. Takes 1200-1400F to get carbon to move. Straight aluminum melts around 1200. The alloy used in this casting probably a bit higher, but still doesn't seem like a totally great idea. It is cool to watch though.
Now I know where to get a light for my cigar:) I've watched a load of videos on youtube and this has definitely been the coolest (pardon the pun), good job as well.
I didn't have an issue, I do suggest put a wet towel over the intake and have water hose run on the intake to dissipate heat quicker, thanks for watching.
+Anderson E Rockefeller Yes.. because of the intake manifold doesnt made to operate in that high temperature. just to be cautious of that intake surface warped or anything happens. but this sure look fun though...haha
+Anderson E Rockefeller could always use a box fan in the direction of air flow, helps keep the flaming bits of carbon out of your face, and keeps the intake cool at the same time.
Mr. Anderson. lol. Sorry. I like throwing mister in front of first names occasionally. And that just has the extra benefit of cool Matrix moments. Anyway, if I were to risk ruining an intake manifold doing this because it was so much work to clean it that if it didn't get done quickly I'd rather buy another one, I'd let it cool as slow as possible and do nothing to cool it or keep it from getting as hot. You see, that makes the metals more brittle when you do.
***** Just use a good chem dip. Easy, quick, doesn't risk bending your intake. Your car may be more responsive afterwards. Is it a 4 cylinder? Most of those have more power down low with smaller intakes than stock. It may hinder performance until you're at a higher RPM.
***** if you're serious about keeping it clean, add an oil catch can to your PCV system. Empty it each oil change or find you only need to empty every 10k miles. It all depends on if your engine is worn. Mostly, the PCV helps you burn gasoline your engine didn't keep in the combustion chamber. It also reduces fuel in your oil, which reduces carbonic acid, which over time erodes your engine.
Wouldn't have believed it unless I saw it. Really amazing.. Also, I had no idea that the manifold sitting on my shelf could be such a raging inferno :O) Enjoy "shade tree fixes". p.s. I would sleep with one eye open.
Yes, but while the carbon deposits are what's burning in the manifold, the combustion process is still dependent on the oxygen in the air that is being blown through. Since the fuel is being burnt by means of a gaseous oxidizer being pumped (or blown) through it, it's a hybrid.
People please check online to make sure your intake manifold does not contain magnesium before doing this. Some foreign car companies put magnesium in their intakes. Not very often though.
love the pyrotechnics I tried cleaning it out with some carb cleaner I use the solution that comes in a bucket for your carb and it didn't work I didn't want to fire up my manifold is the only Way thanks for the video is really helpful
Kids let's try this at home. clean your manifold and have fire works just like on a Holiday celebration all in one, but you get to clean up the mess though. Great video.
Dramatic and fun to watch. You might be generating enough heat to crack or warp the manifold or to alter the alloy and make it brittle. I don't think that I've ever seen a manifold with that much buildup. I think that I'll stick to using some organic solvent, some patience, and a brush. I'll try your technique to remove any left over residue.
+John Ferguson Jeez... this will definitely warp it. How long it was? 5 minutes? I got mine soaking for 2h in decarb solution and then just used brush... Also, jet wash is brilliant, I had no problem whatsoever to decarb... but this...
Many times doing something slower is actually faster for long term... What if it's cracked... what if it's bend? Funny bit is that he may not know that is cracked, but his turbo will definitely feel the pain...and blasting with jet wash is not that slower anyway...
derredriver Thats wen you just disable all the emissions crap if you dont have emission tests in your area. My 2005 silverado has no emission equipment. No EGR, cats, ect..
+derredriver: Yeah, yeah we hear ya - Grape-Nuts taste like _SHIT._. BUT, if it wasn't for "tree huggers" puffing granola farts every now and then, being outside would mean stinging eyes and coughing up furballs for all of us. Don't believe me? Take a look at any recent photo of a large city in Chy-Na. *That's* what happens when people don't give a fuck and piss and shit where they sleep. I'll take CATS/EGR/EVAP, clicking fuel-caps and a granola bar over that ANY DAY...
BluntForceTrauma666 dont live in a city and you wont have to deal with that shit to begin with. Why i live where i live. Its legal to not run anything emissions wise
@TIRONI VITTORIO Yeah they were manifolds mainly from VW TDi PD engines. They were seriously restricted with soot. Made a noticable difference to performance especially on the lower powered ones
Dear Anderson, I live in an apartment. Would it be okay to do this in my living room? Thanks! Seriously, I use oven cleaner and would be a bit concerned using your method due to potential warpage. That said, it's an awesome technique and will make you the center of attention at the summer block party.
Had this same concern. Waste oil furnaces use this exact method to melt aluminum. Usually you get them hot with wood and a blower, then start the oil feed. I'd definitely have concerns about this bolting back up and having leaks. Great fireworks display though :)
that's exactly what I was thinking too, does not look to good to heat up a intake manifold that hot , especially when you can just soak them in naptha solvent overnight and it will be clean as a whistle in the morning
this is a solid aluminum intake, and thick too. If fuel combustion for 100k miles doesn't warp a head, it won't warp a manifold like this after 10 minutes or so.
Cool show maybe I'll get video when I do my cast olds v8 manifold Also to all the peeps worried about warpage manifolds can be easily fixed with a little machine work or a big piece of sand paper on a flat work bench
I think this is a great idea. Not something you’d do to a customers car especially if they’re watching... the likelihood of any warping would be slim as the as the flanges aren’t getting all that hot the focal point of all the heat is going to be near the end of the airline inside the cast. The amount of ejected debris is amazing.. shame all my manifolds are plastic
