We are specialists in Carbon cleaning in Cape Town. At Racing Technik we are the Official and only Carbon Doctor Branch in Western Cape. Carbon Doctor procedure utilise walnut carbon blasting/vacuum process as it is both cost and time affective guaranteeing the shortest turnaround in order to get the vehicle back on the road. Other methods currently used necessitate the use of strong chemicals and metal brushes that damage piston rings and valve stem seals, this is especially applicable to spray-in high revving products such as Seafoam

This unorthodox method requires the inlet to be soaked overnight creating both a time delay for the customer as well as facing corrosive risks on aluminium components. We offer walnut carbon blasting/vacuum services that have proved itself as the most cost efficient method worldwide which was designed, introduced and approved by BMW.


The walnut blasting is done without major engine stripping, we remove the intake manifold to gain access to the valve stems. The engine is then rotated ensuring the valves that are cleaned are fully closed to prevent any debris entering the cylinder bores. The special cleaning system fits perfectly into the intake port, linked to an industrial vacuum and the walnut blasting equipment. Crushed walnut shell granules about 0.5 millimetre in diameter are then blasted directly on the valves and intake port, the walnut shells are hard enough to remove the carbon but not hard enough to damage the valves or intake port. The vacuum cleaner sucks out both the carbon & walnut shells. This carbon cleaning process is repeated several times until clean and repeated for each intake.
