Walnut Blasting: Carbon Cleaning

What is Walnut Blasting?

As you might have guessed it involves walnuts, or more specifically, crushed walnut shells which are ground into a powder. The walnut powder is used much like sand in the process of sandblasting but walnut shell powder is much less abrasive than sand and walnut blasting won’t damage your engine.

At Norlang Auto, we are frequently told by our customers that they believe the performance of their vehicles has decreased even though they service them and change the oil on a regular basis. As the mileage of your car increases, it starts to become more sluggish and not as fuel efficient as it was designed to be. This is due to carbon build-up or carbonizing that occurs in the intake tract and valves. This problem is one of the main disadvantages facing modern vehicles with two-stroke and four-stroke gasoline direct injection (GDI) engines. GDI engines are found in more and more models since manufacturers are able to increase fuel mileage, power and efficiency much more effectively than with any other type of fuel injection system. This type of engine is normally found in European vehicles like Audi, BMW, Mercedes-Benz, Mini Cooper, Volkswagen and many more. It is found in many North American, Japanese and Korean models as well.

Walnut Blasting

Our experienced and highly trained technicians at Norlang Auto will blast away the carbon build-up using specialized tools, walnut powder and compressed air. Once the carbon build up is gone from your intake tract and valves, your vehicle will perform as it was originally designed.

Carbon Build Up And Its Effects

GDI engines may offer you lower fuel consumption and more power than engines with a conventional fuel injection system but since your intake valves are not bathed in fuel, they are not kept clean. Eventually, carbonized fuel and oil build up in the intake tract and valves and will affect your vehicle’s performance. As the carbon deposits build up, they can prevent the intake valves from closing properly, resulting in a bumpy idle, vibrations, reduced power, engine misfires, the “Check Engine” warning light being activated and an increase in oil consumption.

Recommended Frequency Of Walnut Blasting

Vehicle manufacturers like BMW, recommend that we perform walnut blasting every 50,000 kilometres in order to maintain fuel efficiency and keep our vehicles running at their peak. In general, most manufactures recommend that we perform this service between 35,000 and 65,000 kilometres. Naturally, how often we walnut blast our vehicles’ engines depends on our driving habits, the quality of fuel that we use and how well we service our vehicle.
