Walnut blasting removes carbon build-up from your engine’s intake and valves. It improves engine performance, saves fuel, and stops problems like rough idling and misfires, especially in direct-injection engines. Crushed walnut shells are blown in with air to clean the parts gently without harm.
What It Is
Process: Walnut blasting involves high-pressure blasting of finely crushed walnut shells to clean carbon deposits from an engine's internal components, primarily the intake manifold and valves.
Why it Works:
The walnut shells are hard enough to chip away carbon but soft enough not to scratch or damage the metal of the intake manifold and valves.
Benefits
Improved Performance: Restores lost horsepower and torque, resulting in a smoother throttle response and better overall engine performance.
Better Fuel Economy: Increased efficiency in fuel consumption.
Reduced Misfires: Eliminates rough idling and engine misfires that can occur with heavy carbon build-up.
Extended Engine Life: Prevents further damage and wear on engine components, potentially leading to a longer engine lifespan.
Safer for Engines: Unlike harsher abrasives, walnut shells are a safe, biodegradable material that won't harm the engine components.
Why It's Needed
Direct Injection Engines: Modern direct-injection engines are prone to carbon build-up because they lack the fuel wash over the intake valves that older systems provide.
Symptoms of Build-up: Signs include loss of power, poor acceleration, decreased fuel efficiency, and a rough or shaky idle.
