What is Walnut Blasting?
Walnut blasting is a process that some dealers use to treat carbon build-up.
Direct injection is becoming more common because it allows manufacturers to increase fuel mileage, power, and efficiency.
Cars require good oxygen flow to go. Every time you put your foot on the accelerator you are telling the car to release 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, altering the compression ratio, operating temperature and sensor readings on your vehicle. It addition, it builds up and coats the inside of your engine including the air intake valves, combustion chamber and exhaust which restricts your car’s ability to perform properly. It also affects your car’s efficiency and power.
So when the carbon builds up, one of the common ways to clean it out of your engine is through walnut blasting.
How Does Walnut Blasting Work?
Walnut blasting is when crushed up walnuts are blown into the car’s engine with an air compressor. It works like a sandblaster, except that if sand gets inside of your car’s engine, it will wreck the engine. That’s why they use crushed up walnut shells.
How Often Does Does Carbon Need to Be Removed from your engine?
It depends on a variety of factors; Your driving habits, the quality of gas you use, how well you take care of your car…etc. Some dealers would say however, that it should first be done between 22,000 and 40,000 miles.
What are the results of carbon build up?
Loss of power which can be unnoticed because it’s a gradual loss over time, engine misfire, not specific to a cylinder, random engine misfires, check engine light codes, P0300, P301, P302.
Other symptoms of carbon build up include: Check engine light, sluggishness, extended starting times, extended cranking, cold weather startup affected.
