Mitsubishi Pajero Diesel Soot Manifold Cleanout
This is a video about Me and my friend Samuel from Gold Class Automotive opening up the intake manifold of my 2010 Mitsubishi Pajero to give it a big clean out.
Inside modern Diesel Engines there is a build up of dirty black soot. The reason for this is because they run an EGR or Exhaust Gas Recirculator. These divert some exhaust soot back into the intake system to have it get burnt again and make the emissions better. This however fills the intake with this soot that also mixes with recirculated oil vapour. When the oil vapour and soot meet they combine and coat the inside of the intake manifold and over time build up to a large muddy gross mess.
Today we cleaned it all out with Oven Cleaner and High Pressure Water. We also fitted a Catch Can. We fitted a ProVent 200.
I hope this video has helped you see how necessary it is to do but also I hope to get better power and economy out of my engine.
At Kap Industries I like to bring interesting videos but also show you my business where I make Fire Extinguisher Brackets for vehicles.

Always good having mates as mechanics willing to give you a hand. 👍🏼
Hundred percent. He always helps me out!

Oven cleaner is very good on carbon removal, the Mrs is always using it after her attempts at cooking!
Bahaha well played
Shots fired
Yes but not so good to breath
Just did mine 2007 ML, took me 24h. Few words of advise to whom wants to jump and do it himself. Plug all fuel ports after removing them, use advised cleaner only on the inside and mask gasket surfaces, otherwise it might corrode the aluminum fine finish. Once is all back together you need to manually pump and purge rail and injector lines and let all the air out by undoing small bolt on top of the pump, do it several times.
Totally impressed how well you guys made it look! I don't know this engine platform too well, but I'm a huge fan of the stuff Mitsubishi put out in the 90s with their gasoline turbo engines and drivetrain. This was mindboggling!
I had the same car, NT Pajero, did over 200000ks oil changed every 10000ks with Penrite semi synthetic. When I sold it the guy had his mechanic check the intake with a scope and there was no build up at all. No catch can or EGR delete. Just change the oil and drive it hard. Moral of the story is you don't need a big diesel for the school run, they don't like chugging around the city.
Catch can could damage the engine!! its just a snake oil salesman. Your advice is wise and I totally agree.
My 38 ft troller loves chugging around the sea. Hour after hour. Don't tell me the diesel buses in London don't like chugging around the city streets or driving the kids to and from school.
I call a big bull💩 on that one.
Installed a catch can on mine at mechanics recommendation and every service always replace the fuel filter.So far have had no issues and the Pajero has proven a reliable vehicle.
My Mitsubishi Triton 2008 3.2L ran 350,000kms and I haven't clean the intake manifold. I already experienced hesitation and power lost. I think it's about time to that cleaning. Thanks for the vid!
Its hard to believe how much build up it has inside the inlet. You've done a great job cleaning it up.
The Burr Shed thanks buddy!
A lot of the buildup is caused by stop start, short trip city driving, which diesels we’re never designed to do. Long regular runs and frequent oil changes will reduce this problem. However, a catch can is a great idea to help reduce this problem.
One thing i like about the newer vag TDI engines is that with the the seprate low and high pressure EGR systems, you get all the combustion condensation pushed through the intake, steam cleaning everything and keeping it pretty clean. Although the DPF can have issues if you mainly do city drive ming so that regens never completely finish.
Those probes in the first part of the plenum with the throttle body attached, I'm surprised they were even doing anything and not throwing a check engine light. Even more of a reason to delete the EGR system on my vehicles.
Would be good to see a dyno run of before and after something like this, I bet the regained power is very noticeable!!
When my truck turned 25 and became ineligible for emission inspection, I put a 4-barrel carburetor and non-EGR intake on it. It runs better, makes more power, and is much more pleasant to drive
Diesel pro tip. Make sure you add fuel additive. Hotshots is really good. They make a oil additive to eliminate stiction and removes carbon buildup on the oil side of the engine, it sounds like you are from Australia so you can run the hotshots extreme system clean till the bottles gone and then the everyday ( every tank ) they boost cetane, clean injectors, prevent water separating and give the much needed lubricity back to the fuel that is removed in refining. I used to run this in my 7.3L power stroke and it loved it. Good smooth running engine.
EGR good for enviroment, but its killing your engine 😂🤣👌
DPF it's worst than EGR..! The EGRs give you problems if you don't clean it every oil change but only at long term.
No egr, dpf, cat, no problems. Fuck enviroment.
Honestly egrs don't even do much and def is SOOO bad. Spill some def nothing will grow
@@anthony2002able all enviroment bullshit is bad.
yeah, so good for the environment, you have to burn twice as much diesel because the engine is so gummed up. It is like the high efficiency toilets, you have to flush 3 times to get your turd down, and use 2x as much water as a standard one.
6:05.. great fertilizant for plants
Carbon to carbon. Carbon life all around.
This carbon might kill plants & trees. Good position for them.
Haryanvi Baman how
@@jellyfrosh9102 coz its a chemical based , burnt hydrocarbon.
Forget the carbon what about the oven cleaner
Thanks guys. One of the best/worst? examples of soot cancer I've seen.
Good job brethren wholesome cleaning, That Pajero will run another 100-150k kms.
Blast it with dry ice, goes fast and the result is fantastic.👍
Manufacturers on the latest generation Diesel engines are now tapping into to exhaust gases after the DPF so the soot and oil contents are negligible. Protects the EGR and air intake. Latest VW diesel family EA288 uses this new method It’s a no brainier I guess that’s evolution for you. With diesels now having to be tested to real world conditions and sustain clean emissions for the life of the car it’s forced manufacturers to up there game. The emissions must have been impacted by all that soot. Thxs for the video guys I was shocked at the amount of soot.
Wow i did not know that! Thanks for the info! Please sub if you like
Audi,Seat,Skoda,VW,Ford,GM will not rev on the emission test so they pass because the vehicles know they are staionary and so when the gas pedal is pressed they inject such a small amount of fuel that they rev to their progammed limit of @2500 rpm and nothing comes out the tail pipe, the machine does not register any smoke detected and so it passes.
@@mazdaman1286 lmao sure mate, because the USA's dieselgate taught them nothing.... the DPF caughs all soot making your exhaust contain by regulation less than 0.5ppm of soot in it, SCR's do their job and decompose NOx from the exhaust to 0.5ppm. i do you really think they would just pull that bullshit off when VW tried and was left with a multi million dollar buy back and thousands of vehicles essentially unusable waiting to get crushed?
Nice one Russ! Crazy build-up
Thanks! Yeah so gross. Such a great cathartic feeling cleaning it all out!
@@kapindustries9236 hello. Thanks for this video. A question, please : those soot builds up on 150.000 km, although using oil catch tank? Warm Rgrds from Bali Island
I'm a marine engineer, this soot is nothing compared to what we clean on ship's engines. 😄
I can imagine!! Gross!!
Soot blow in progress. Call bridge
@@aaronwon1143 engine cadet here ✌️
@Mohd. Syahfiq Al-arby i think you can
Agreed, I've lost count of the scavenge cleans I've had to do on sulzer 12 96 C engines
That Oven Cleaner is a damn good idea. 👍👍👍👍
Car weight Before clean up = 2500kgs After clean up = 1950kgs
Bahahahaha true!
Lol
Great job and Mr Gold Class didn't do too bad either
Haha thanks boss!!
Hi, Thanks for the video, just done the same to my Mercedes, cannot believe how much soot was in there. Mess job but needed doing.
Yeah its crazy hey!! Good job!
What was the mileage on it when you done it
@@ollie-kc6nj It was 90,000ish mile if that helps?
@@johnoakes5440 damm mines never been done 250,000 km
All due to dry intake technology, older wet intakes do not have this issue. Newer intakes like the bluetec mercs have a liquid added to the intake to make it wet and clean it. Those are some of the cleanest engines around.
Any more information on this?
It surprises me that most people don't even know about using oven cleaner when dealing with engines. You proved how well it works. I don't know of any other product you could have used and get the same result. Whenever I go to the dollar store I always pick up a couple cans just to keep it on hand when I need it. I liked your video. and I'm glad you showed how dirty the parts were.
Oven cleaner does seem to do the trick! Word of caution though, it isn't meant to be used on aluminum (i.e. alloy engine). While I think it is safe to use if you wash off straight away I can confirm you shouldn't leave on for extended period of time. I used the oven cleaner where you put it in a bag over night and it damaged my intake manifold (beyond being able to use). Hopefully this message saves someone else some grief... and saves another innocent intake manifold from being perished
@@jabezrenko indeed oven cleaner may work but it pits the surface of the aluminium making the problem worse as the surface is "grippier" for the soot to attach to. I have tried acetone which is used as a degreaser which was pretty effective, but there is only one product so far that has worked better which was a degreaser called Surfex HD made by a company in the UK - it is water-based which seems counter intuitive and I only happened to have a jug of it which I bought years ago but I was shocked how well it worked with a hot soak - safe for plastic manifolds and my EGR cooler came up shiny - some mechanical scraping for the really hard bits is also needed but I'd sooner that than risk oven cleaner...
1:1 deisel Gasoline mix good for cleaning that kind of soot
Good call!
Invest in an ultrasonic cleaner! The parts would look brand new.
I'm curious about performance/fuel economy changes from that. You gained alot of volume in your intake and increased your ports usable diameter.
I just clean the egr system for may dad's bighorn. Its the worse I have ever seen similar to yours lol For the intact valve in the head, I just spray it, brush it, pour petrol in there and brush it until its clean & shinny like new. But before I pour something in it, I make sure I only clean where the valve is in close position. Once I clean the close valve part, I push the car while the gear engage and the close/open valve is changing position. I continue to clean the other close valve where I haven't clean yet. Everything went perfect.
Maybe one of those silicon icing spatulas would work nicely. In my mind it would
Great job lads 👍
Thanks boss!
Amazing how much carbon build up there is. Great clean up.
That’s crazy plugged up
Hi Guys Nice Job you Did of cleaning .watching this in the UK as I am wanting some tips on how to do this myself .after watching I feel more confident in giving it a go .did you give the electronic throttle body a clean as well .
Finally, sound like a diesel 😨 Edit : good job!
I have a 2.8 Pajero/Montero, I disconnected the EGR control. It wasn't working correctly and dumping my turbo boost. I still get oil in the intake from the blow-by tube, might look into the catch can.
Would’v been great to have done a before & after dyno for curiosity reasons!
Excellent video master
You can also take a torch and a lot of compressed air to burn it out
You can also use hard plastic to scrape off those.
hey mate, did an intake clean on my ml triton last year and you're meant to get those butterfly valves in the intake freed up if you didn't, helps it run much smoother
Hey i didnt realise that! Hmm i might have to pull it apart again. Thank you for letting me know
Insane. Nice job
Please, i would like to know how did you managed to clean the cylindre part without the carbon going to the valve?
If that engine could talk. Thanks mate I can breath again. Crackin good job
Fark! That car is the same age and km as mine. I've got a Provent catch can I'll be adding and also get the inlet cleaned out. It'll be like having a new engine again I reckon. Thanks very much for posting this video, I'd never have know otherwise and I guess there'd be the real chance of the engine failing prematurely otherwise.
Yeah its crazy hey!
Brake dust remover works like a charm in cleaning. It's made to remove carbon deposit and the soot is carbon deposit
One reason the oven cleaner works so well is because it is also made to break down oils and grease that have been baked down and polymerized (Also why you should keep it away from your cast iron pans)
Really good job 👍👍👍 ❤
Nice work 👌
I kept thinking how you guys could’ve used a rubber spudger to remove the soot and carbon and crap off instead of using metal against metal the best
Nice job. I've used the oven cleaner trick myself on my old Triton, and I'll be doing my NT Pajero very soon along with a Provent can...
Yeah works a treat. Im really happy with the provent also!
@@kapindustries9236 as it turns out, I'm fitting a Ryco instead of Provent...only because I got one on a super special for under $130 and they're almost as good.
Mitsubishi Pajero.............. Greetings from Latam. Also great job!!
Can you tell more detail about the history of the car? Like milage, air filter cond, etc.
RIP garden, soil and probably underground water (if there is any). Still a great video and very educational.
Get a sonic clean - fit a catch can - job done! My intake manifold looked just like this, but now runs like a rocket when needed and sits on 7.6lt to the 100 when I'm being sensible! Which is almost always now due to fuel prices.
Good day sir..id like to ask if oil catch can really helps to polong the engine of diesel vehicles sir
Great job
Thanks!
Awesome video, can you please do a video on how to remove and clean oil silt from the turbo.
Hi mate, what do you mean?
@@kapindustries9236 sorry I've never own a Triton before this my first time asking for help on how to clean it to save me some money.😁
Nice black mushy peas good job use to it done many 2.2cdti honda good job lads
Thanks boss!
investing every now and then in a new airfilter to provide your engine with clean air and then stick a egr on it... MADNESS...
Great job.
Good job mate ... what is the product cleaner ever for this job guys ??? Thank you guys ...best regards
That is a fantastic video fellas thanks very much that will be the next thing I'm doing on my Mitsubishi Pajero turbo diesel just finished doing the gearbox 5 speed automatic that was a hell of a job because it's my first time flushing out the gearbox and torque converter took me probably 5 hours 2015 model, Mitsubishi the cheeky bastards doesn't even have a normal dipstick there's a hidden one in the oil pan under the car but I saved myself $440 bucks after paying for the oil love my hoist bought a hoist just so we could save money the Hoyts has already paid for itself only talk about Turner bit years Hoyts cost 5 grand I work on my car my son works on his car his girlfriend's car and his mates can't live without it thanks again for the great job and upload fellas
Thanks so much for the kind comment! Would love for you to check out my product I make for the Pajero. kap.industries/product/fire-extinguisher-bracket-mitsubishi-pajero/
Very satisfying. How did you clean the intake ports? just scrapping them off? And how many bottles of oven cleaner did you use for this cleaning job?
Great video.... Catch can in. Ta
Don't think that the egr is only on diesel's because the 94 Pontiac sunbird I had was a gas engine and I cleaned the egr valve myself before eventually replacing it.
My 99 Tacoma has it.
The ports you can scrape and vacuum at the same time
Did you guys check the piping from turbo to intercooler to throttle body too? This is oddly satisfying, like brand new
Does that get gunked up too?
Prevent catch can and Munji EGR delete cable. 2015 NX Pajero. Best thing ever!
Hi there! I realize this video has been around for a few years now but one question. You say this problem occurs in all vehicles - would that include a 1995 Navara ute which I have?
Great video, I learned a lot! Q: instead of exhausting these pollutants, the 'solution' is to EGR it, catch it then wash it out with another chemical and put the waste ... where? Overall, the environment loses 'every which way' 🤔🤯😂
Put the waste on the EPA's doorstep.
+25hp lol Impressive! Good job!
Love this! Did you notice improvement in power or economy over the past 1year ?
Egr delete and the intake problems are solved 👍
EGR = inferior bandaid technology.
also deletes the legality of your vehicle
@@TORTLESSS not here in sweden where they don't check it 😎
@@ralfrisberg8009 don't think anyone checks it man after registration, but let's respect the law and the environment
@@TORTLESSS they used to check it every year but then all of a sudden they stopped doing it and on my Volvo 240 the egr valve was only making it use more fuel so delete it and have a happy life 👍
Can you take a photo before and after cleaning How much lost weight
I wonder if a teflon non-stick coating could prevent this
I can't believe you blow this stuff into your garden🤯.
Do you reckon id need to bleed my injectors if its a direct injection engine rather than an indirect common rail??
You replace all gasket or used old one? And one more question can we use liquid gasket?
Wow thatl be a completely different engine ..feel like uturned up the boost
Ohhh yeah! Heaps better. Please sub!
I bought a Pajero , from new I installed a provent 200 filtered catch can , remapped and had egr turned off completely, this crap should never build up in mine . Therefore stay fuel efficient and powerful for the life of the engine , and eliminate all these problems in the future, systems like egr may reduce pollution when new but it comes a point when these engines will use more fuel and pollute more due to this soot issue . As you say all diesels will create this mess , but you can prevent it.
Can you use oven cleaner?
Very satisfying
Thanks!
Nice demo, thx. But letting all the blackness just to flow in your garden ... I don't know.
Easier and less time consuming way to clean it is to light the carbon on fire with a oxy torch and once it’s burning shoot compressed air in the manifold to help it burn faster. Works like a charm.
Great for the environment too I bet
How did you get the ports in the engine clean without that crud falling inside
Butter fingers engineering!!
hahaha
Number 3 cylinder on my 3.2 Triton is way down 75 psi the others are around 390 i wonder if theres crap built up around the valves ??? Catch Can and Oven cleaner thanks mate will definitely give it a go 👍
Did u guys end up cleaning out the intercooler, it would have oil it in as well.
Nice stuff, curious how you cleaned out the ports on the engine side without getting carbon into the cylinder? Did you idea vacuum or something as you scraped?
I didnt see how he did it sorry. I think he just carefully scraped it out.
I'd say a good way to do that would be to carefully scrape the buildup off, but keep a shop vac or some sort of vacuum nearby. Keep the suction as close to your scraping tool as possible, and take your time.
@@nathanheaverlo9626 @UCRlEx829Pxoe_wZSb7dJwhA thanks that's what I was thinking but my mechanical knowledge is still basic!
I understand they turn the engine over to close the valves, clean and remove all junk, then turn it over to close the next valves, and so on.
Any idea on power/fuel use Change
My Fiat 1.3 16 valve diesel had a broken cam chain (easily fixed surprisingly) but the intake was almost blocked solid with soot. I dunked its (one piece) plastic manifold into a bucket of caustic soda (lye in USA). Unfortunately, that’s not an option for any aluminium parts. They had to be manually scraped out. I had the head off to check bores and rings so did a proper valve job. If it’s left on the engine, you have to blast it with walnut shells. Turn engine to close the valves of course.
hi thanks for good video, I have done manifold clean following your steps, but my pajero cranks but not starting. what would be the problems?
I would recommend bleeding the injectors
Yes bro awesome 👍
Petrol would clean it out well too right ?
Hi bro I just bought a pearl white RX just like yours! Where are you located I’m looking to get this decarb done by someone with experience
Hey mate im in melbourne. My mate who is the mechanic works out of Frankston. Let me know and ill see if he is keen to do another one.
Yes, so not just EGR, rather oil mist/crankcase gas is alse fed back to the intake
Plumber blow torch burn off a good bit of oily shite then oven clean. With two stroke bike pipes an oxy torch up the disconected exhaust get it burning and take off the acetylene and oxy only, whilst using a water hose to stop the chrome blueing off. Lots of smoke LOTS of smoke but a huge power increase after.
Didnt know that! Thanks
