Autowerx BMW and Walnut Blasting

Walnut Blasting

Modern direct injection engines have significant performance benefits over older conventional engines. However, there is one drawback to this system in that over time the injected vaporised fuel leads to a steady and gradual build up of carbon deposits in the fuel intake system. This then has a detrimental effect on the efficiency and overall health of the engine.

Every modern engine over 30,000 miles will be suffering from this to some degree. Carbon deposits are tough and difficult to remove. Bathing the engine in cleaning fluids will often not be enough to solve the issue effectively. Walnut Blasting the intake system provides a much more effective solution to the issue.

What is Walnut Blasting?

Walnut blasting uses pressurised air to inject fine walnut shell granules into the intake tract. These granules hit the carbon build-up at high speed and remove it entirely.

The reason that Walnut shell is used is because it stikes a perfect balance between durability and softness. This means that it is strong enough to break apart the carbon build up but soft enough not to damage the lining of the intake system. This is why no other material should be used for this method.

Not only is this method safe, fast and effective it is also the most cost effective as it negates the need to perform an expensive and labour intensive strip and rebuild of the engine.
