Frequently asked questions :

What Is Walnut Shell Blasting? 

Also known as Walnut Shell Cleaning, Walnut Shell Blasting is a service where fine particles of milled and processed walnut shells (the same kind of Walnut that you eat) are fired at high pressures into the intake port of the engine cylinder head, and recovered simultaneously under vacuum.

Why is it needed? What do you do? 

With the advent of direct fuel injection, fuel (that also contains some detergents) is sprayed directly into the combustion chamber. This is highly efficient for the engines power and fuel economy, however cleaning of the intake valves and ports is no longer talking place. 

With conventional fuel injection, fuel is sprayed into the intake track, and some fuel works with its detergent properties onto the valve and intake track.

Buildup begins when the combustion byproducts of burnt fuel travel backwards into the intake track, and the carbon byproducts of the burnt fuel collect and form "carbon deposits."

In Direct Injection engines, carbon is no longer naturally dissolved from valves and ports in the normal running process, and manual cleaning becomes a requirement. 

Walnut Shell Blasting is a safe way to clean the valves and ports. Blasted at high speeds the Walnut media effectively removes carbon deposits and is a quick and easy way to restore performance and economy to your BMW direct injected engine. 

Unlike sand and other abrasive media, walnut shell granules don't wear metal - they only remove deposits that aren't part of the intakes original design. In essence, walnut shell blasting only removes what is necessary, quickly and safely- which is why it has become the most viable solution for cleaning intakes and the method that BMW uses.
