Engine Carbon Intake Valve Walnut Blasting & Direct Injection Decarbonization

Advanced mechanical carbon-cleaning service specifically designed for modern direct-injection (GDI) engines. Due to the fuel injector placement, carbon buildup rapidly accumulates on the back of intake valves, choking airflow and causing rough idling, misfires, and power loss. Using a specialized pressurized walnut-shell media blasting rig, we safely strip away hardened carbon deposits right down to the bare metal without damaging the valve seats or combustion chambers. Price varies depending on the complexity of the task.
