Walnut Blast in Killeen, TX

A walnut blast service is a method used to remove carbon buildup from the intake valves of direct injection engines. In direct injection engines, fuel is sprayed directly into the combustion chamber rather than being injected into the intake port. This can lead to carbon deposits building up on the intake valves over time, particularly in areas where fuel doesn’t flow to clean the valves.

During a walnut blast service, crushed walnut shells are blasted into the intake ports and valves using specialized equipment. The walnut shells are abrasive enough to remove the carbon deposits without damaging the valves themselves. The process effectively cleans the intake valves, restoring proper airflow and engine performance.

Carbon buildup on intake valves can lead to a variety of issues including reduced engine performance, rough idling, misfires, and poor fuel economy. A walnut blast service is a proactive maintenance measure to address these issues and keep the engine running smoothly. It’s often recommended as part of regular maintenance for direct injection engines, typically around every 60,000 to 100,000 miles, but this can vary depending on driving conditions and manufacturer recommendations.

In addition to the walnut blast service for removing carbon buildup from the intake valves, we perform direct injector cleaning using ultrasonic technology.

During the ultrasonic cleaning process, the direct injectors are submerged in a cleaning solution and subjected to ultrasonic waves. These waves create millions of tiny bubbles that implode near the surface of the injector, effectively scrubbing away any built-up deposits and contaminants. This thorough cleaning helps to restore the injectors’ spray pattern and fuel atomization, ensuring optimal engine performance and fuel efficiency.

Combining the walnut blast service with ultrasonic cleaning of the direct injectors provides a comprehensive solution for maintaining the cleanliness and efficiency of the engine’s intake system in direct injection engines. It’s a proactive approach to address carbon buildup and injector deposits, promoting smoother running and prolonging the lifespan of engine components.
