Intake cleaning, soot cleaning, decarbon

Before Clean & After Ultrasonic bath Clean, Its like brand new.

The #1 killer of a modern diesel engines power and fuel economy is a blocked intake and this is where an intake clean is needed.
More then 50000ks on your diesel engine then its time for a intake clean, some vehicles don’t build up as much carbon sludge as others, its all in the design of the emissions control systems however every vehicle with a common rail diesel engine will have some sort of carbon soot build up in the engine and this is the number one killer of reducing power and fuel economy and eventually will lead to serious engine damage.

Why does this happen?

It all comes down to trying to control the harmful emissions from vehicles hurting the environment. Manufacturers have installed such devices as EGR Valves which return burnt exhaust gas from the engine back into the intake of the engine to be mixed with the clean air and burnt again. This is great in principle however they also return oil vapour from the engine ventilation system into the intake and this mixes with the EGR gases and creates the sludge, carbon, and soot build-up in the engine intake system. When this is really bad such as 200,000klms we find that not only is the intake manifold very badly blocked but the cylinder head ports and valves are coated in this terrible stuff.

Why doesn’t my mechanic do this and why haven’t they told me about this?

Your mechanic may or may not be aware of the issues related to new CRD engines either way almost 95% of mechanical workshops don’t have the equipment, experience and training to carry out such work on these engines and yes that most certainly includes all dealers, we regularly get vehicles to come straight from the dealer which can’t be fixed and we can diagnose and repair them with our specialty equipment and knowledge.


If you’re experiencing any issues or are in need of some information relating to intake cleaning then give us a call and we can run through any questions you may have and any quotes related to any of our cleans.
What will happen if I don’t do an intake clean on my engine?

Inevitably your engine will reduce in power and start using heaps of fuel until it has a failure and will cost you thousands if not render the vehicle to be sent off to the scrappers.
We all know the stories of an old Toyota Landcruiser doing 1 million kms on the same engine and yes I can testament to that being Toyota trained I have seen plenty with serious kms on them. However, these were a differently designed engine before emissions and this is no longer something that can be achieved from a small displacement modern common rail engine.
We see all to often CRD engines that are blown up or had major failures with 250000klms on the clock when they have had regular servicing.
How could this be possible if it was serviced well they may have been serviced but not serviced properly by a diesel expert who knows what to look for and also has the machinery to repair these faults that slowly build up.

diesel particulate filter


Have you got a DPF light on the dash or have you been told your vehicle needs a new DPF by the dealer or a workshop or do you have a DPF issue that a dealer or workshop can’t fix for you?

We have the alternative answer for replacing an average of $6000+ DPF, we can clean your DPF for you and we will also diagnose why the DPF is blocked to prevent it happening again prematurely.
A DPF (diesel particulate filter) is designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine and to reduce the harmful emissions from damaging our environment and it’s a great system when its functioning properly and effectively. When its not it can be very annoying for any car owner with problems such as:

  • Engine lights coming on
  • Mass of smoke coming out while driving
  • Very smelly exhaust
  • Very low power
  • Limp mode
  • Very slow revving engine
  • Noisy engine
  • Running rough
  • Very bad fuel economy

DPF Cleaning

How we clean the carbon and dpf soot

As with any filter, its job is to “filter” what’s running through it, and your DPF needs to be cleaned regularly to ensure your vehicle performs at its best. The DPF clean will do wonders for your diesel’s efficiency and its overall performance just like changing your oil filter or cleaning your air filter the DPF is no different.
Your DPF should be cleaned every 100000kms to help with the longevity of your common rail diesel engine.

  • Avoid out-of-pocket maintenance costs and extend filter life – Regular cleaning helps extend the life of your filter as excessive soot and ash collected in the DPF can damage its core structure
  • Improve fuel economy dramatically
  • Improve power and performance
  • Help improve the environment (every little bit helps)

You may be having a DPF issue due to the lack of driving out on open roads which as a car owner this should not be a prerequisite, we should be able to drop the kids off at school go to the shops and home etc however these short stop start trips are a DPFs worst nightmare and will not give the car the opportunity to give the DPF a clean while driving.

You may also have a DPF issue that is caused by other things not running properly with your engines associated systems, in a lot of cases this is what we find.

The DPF cleaning process removes all the fine particles that have built up internally inside the filter, after cleaning the filter it is rinsed of the remaining chemicals and tested for correct operation, if there is any other associated issues we will rectify those before refitting the cleaned DPF and once complete we will test and then reset all associated engine adaptations so that the engine is performing properly again as it should.

How we clean the carbon and DPF soot.

We have a state of the art large industrial Ultrasonic Cleaning bath, this combined with the correct cleaning solutions gets your DPF completely cleaned inside/out.
We also use this machine to clean inlet manifolds and egrs of carbon build up which returns them to brand new.
The cylinder head ports and valves are cleaned using a walnut blasting machine while we have the inlet manifold off.
We do offer a on car cleaning option for both the carbon build up and dpf soot build up, these do work very well in the right applications however in quite severe applications there is no choice to remove and get them into the ultrasonic bath.
On car cleaning is verified by small cameras which we can access down into the engine and exhaust to check the before and after results as well as our complex computer scan tools give us all the electrical sensor data and with our expert knowledge of how to read this we can make sure the results are as desired.
On car cleaning used to be the only option we had many years ago and this has worked great for us and saved so many customers costly repairs over the years. However in recent times with the emissions standards getting tighter and tighter the use of the ultrasonic machine is by far the best way to return the components to a brand new state, the on car machine is great however it will never give the same result as an ultrasonic machine and for this reason it is our preferred method for seriously affected vehicles.

We are more than happy to discuss any questions or vehicle issues you may have in relation to diesel engines in general, DPF cleaning or any other cleans or services please give us a call to discuss any questions and quoting.

diesel Injectors

Deisel Injector CLEANING

A diesel engine in all aspects is a fantastic design, however it all revolves around the diesel being injected into the engine. This alone has many variables such a spray patterns, angles, positioning of the injectors and many other aspects. Once these injectors start to block up even the slightest bit they will start to not perform at 100% and this will cause issues such as:

  • Blowing excessive smoke
  • Rattling knocking noise
  • Poor performance
  • Poor fuel economy
  • Start issues
  • Rough running

The diesel we have available in Australia is of poor quality unfortunately and this means that our vehicles fuel system is suffering long term due to this. With being the most important part of the diesel engine’s system it is important to have it running spot on. A slow build-up in the fuel system of a diesel will cause a slow ramp-off on the performance and fuel economy of the engine, this is when you need to carry out some maintenance on the system.

We can carry out injector cleaning and fuel system cleaning on almost all systems and see outstanding results.
