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.

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.

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.

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.

@rodneywright3370 2 жыл бұрын

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.

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.

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.

@jabezrenko Жыл бұрын

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

@Umski Жыл бұрын

@@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...

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.

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.

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.
