Walnut blasting is now being offered at DJ Foreign Auto Care! What is walnut blasting you may ask? Walnut blasting is a process that is used to treat heavy carbon build-up. Cars require oxygen to run. With modern direct injection engines, when your foot is placed on the accelerator, the car releases gasoline into the combustion chamber of the vehicle. The spark plugs then ignite the gasoline in the combustion chamber, causing the car to run. Carbon is released into the engine as a byproduct of this process.  The carbon interferes with the vehicle’s normal combustion, which in turn alters the compression ratio, operating temperature, and sensor readings.  The carbon builds up and coats the inside of your engine including the air intake valves, combustion chamber, and exhaust, restricting your car’s ability to breathe and also affecting your car’s efficiency and power. When the carbon builds up, one of the common ways to clean it out of your engine is through walnut blasting.

What Are the Results of Carbon Build-up?
The results of carbon build-up include: loss of power (which can go unnoticed because it’s a gradual loss over time), engine misfire not specific to a cylinder, random engine misfires, and check engine light codes P0300, P301, and P302. Other symptoms of carbon build up include: Check engine light on, sluggishness, extended starting times, extended cranking, and the cold weather startup is affected.

How Does Walnut Blasting Work?
Walnut blasting uses crushed up walnuts that are blown into the car’s engine with an air compressor. To perform a walnut blasting, the intake manifold is removed and blasted with crushed walnut shells and compressed air, blasting away all of the carbon build-up so your car will perform like it was originally supposed to.

We’ve found that you need to get the whole system clean for your car to drive efficiently including the rings, the valves and  the intake manifold. Performing an oil change is recommended at the same time as the walnut blasting as well as replacing the spark plugs.

Walnut blasting is not able to reach all of the hard-to-reach areas of the engine where the carbon is caked on, so we can also perform a fuel/air induction service which uses chemicals to remove carbon sludge from the fuel injectors, throttle body, plenum, air intake, valves, ports, piston crowns, combustion chambers and catalytic converter.  Removing the carbon build-up with walnut blasting and fuel/air induction can restore power and fuel efficiency to vehicles such as BMW, Mercedes-Benz, Audi, Volkswagen, Mini Cooper, Jaguar and Land Rover with modern direct injection engines.
