Hi guys! Rob from Ultimate Diesel Tuning.
Today I want to talk to you about a very common issue that will develop in all
common rail diesel engines. As a guide, all diesel engines 2006 onwards, roughly.
This issue can cause a reduction in power and torque
(plus) increased fuel consumption in most cases.
So today, let's talk about this and how we can fix it for you.
Quite simply, the common rail diesel engine's exhaust gas recirculation,
(or EGR), valve recirculates a percentage of the used and dirty exhaust gases
back into the inlet manifold and combustion chamber, instead of simply
sending them straight out the exhaust.
The dry exhaust gases mix inside the engine with the wet oily vapour
produced by the engine's crankcase ventilation system.
This gradually creates an oily tar-like black build-up, which is commonly known as "SOOT".
Over time, this soot then lines the inner surfaces of the engine components,
such as the inlet manifold and the valve-train, amongst others.
As it builds up, it becomes restrictive and it restricts airflow to the engine,
thus reducing the engine's performance and efficiency.
And it can also decrease fuel economy too. As I've said before on
other videos, it literally is like clogging the arteries to your heart!
Soot is produced in every one of these engines and we usually start
to see the build-up from around 30,000 kilometers. At Ultimate Diesel Tuning
we've developed a system and process to remove the soot from your
vehicle that works and is highly effective in doing so!
Today we've got a couple of LandCruisers in the shop, so I want to show
you what soot is and how we remove it...
This one is a 2016 model 200 Series with just over 100,000 kilometers on the clock.
And this one is a 2015 model 79 Series with 170,000 on the clock.
Both are fitted with the 1VD engine, with the 200 Series being a twin-turbo
and the 79 being a single turbo.
These engines are one of the worst for developing the soot issue, unfortunately.
And we've seen it develop badly even at 20,000 kilometers with some Cruisers.
So what we're going to do now, is remove the top hat off the inlet manifold,
to show you actually how much soot build up there is...

We've removed the top hat from the LandCruiser, and as you can see -
this black matter inside is all soot. It's super sticky and restrictive.
To remove this soot, we use highly effective on-car chemical soot cleaning machines.
We spent months and months testing several different concoctions for our
machines, until we found the perfect mix that is very strong so works
extremely well. Yet is also 100 percent safe for the engines.
We don't use any other common methods like steam or aerosol cans -
because they just don't work!!!
You have to also be careful of other machine methods where the chemicals are
just not strong enough to remove the soot.
Let me show you our process and how effective the chemicals are.
Our machines inject a chemical solution at high pressure into the engine,
which dissolves the soot in the direction of the airflow inside the intake manifold
and valve-train, which is where it is restrictive.
It then dissipates out the exhaust as vapour, not solid material,
so it's totally harmless to your engine!
So we're going to put the manifold back together, put it on the machine
and show you the outcome.

Ok, Mark is removing the top hat (after we've completed the on-car
chemical soot clean) to the manifold.
Let's check it out - as you can see, that was significantly built up with soot
all around the top hat. Now we've completed the process, the top hat and
the upper part of the intake manifold is all clean just like we expected
with our on-car chemical soot cleaning process!
As we said before, the intake chemical clean has cleaned all the top hat
as well as the manifold and then through the intake.
And, as you would remember when I showed you this before, this top hat-
it was totally covered in black soot.
Ok guys, I thought I'd do this video today to show you how we deal with the
issues of soot and how we clean it all out.
As I've showed you, and with the time-lapse video, it works extremely well
at removing that soot.
Once we've finished the on-car chemical soot clean, we give the engine an
engine oil flush, as well as replace the engine oil and filter.
We have our on-car chemical soot clean machines in all our workshops
- Brisbane, Gold Coast and Melbourne. So if you've got any questions about
soot cleaning your motor, or any questions about performance-enhancing
your vehicle, give us a call at Ultimate Diesel Tuning and we'll talk to you about it!
