Noticing a change in the performance of your Luxury Vehicle?
There are many perks to owning a German car. From stylish interiors to the incredible engine performance, there is no question to why they are considered a status symbol for many car lovers. However, just like any vehicle, they do have the occasional issue that will come up.
For newer models that have petrol direct engines with direct fuel injection, many cars experience carbon build-up over time. This results in the car experiencing decreased performance, engine misfire, vehicle sluggishness and much more. While carbon build up can be a serious problem, walnut blasting is the solution to getting your car back to peak performance.

To understand walnut blasting, you first need to understand why your car may need to have the service performed. Advancements in auto engineering have seen an increase in direct fuel injection and turbocharged vehicles, as it has allowed for improvements in overall engine performance and fuel economy.
However, this type of engine is not without fault. When you are driving the vehicle small amounts of oil vapour are pushed through the intake manifold, these oil vapours attach to the back of the hot intake valves and create a carbon build up no chemical can 100% remove. The most common way to clean it is through the process of walnut blasting.
The intake manifold gets removed from the engine exposing the cylinder head chambers that lead to the intake valves. We then install a vacuum attachment over the exposed intake port which will vacuum up the carbon and leftover walnut shell once it’s been removed from the back of the valve. We then use broken up the walnut shell in conjunction with high air pressure to blast the back of the intake valves to break up the carbon build up.
At this point, the vacuum will suck up the broken down carbon and leftover walnut shell leaving a clean and shiny intake port. The reason behind using walnut shell instead of other blasting media is because walnut shells cannot damage or alter the machined metal surfaces inside your engine. Walnut shell can also be burned meaning if any small bits are remaining once the job is complete they will burn off once the vehicle is run the first time.
