Our Walnut Blasting Cleaning process

Your vehicle will undergo our Walnut Blasting Cleaning procedure. It will take about 2 days to complete the process.

  • Disassembly and prep

    All the engine parts are dissembled to have full access to the intake valves. Any openings are covered to prevent walnut shell debris from entering unwanted areas of the engine. Pistons are at the bottom dead centre to avoid debris entering the combustion chamber.

  • Blasting process

    Each intake is carefully and methodically cleaned by spraying the walnut shell media at high pressure against the carbon deposits. The process is completed when all internal surfaces shine like new.

  • Injectors ultrasonic cleaning

    Each injector undergoes ultrasonic chemical cleaning to remove carbon deposits and contaminants, while testing measures fuel flow rates, spray patterns, leak rates, and response times to ensure the injectors deliver fuel properly. The combined cleaning and testing process typically takes 30-60 minutes and determines whether injectors can be restored to acceptable performance or need replacement.

  • Clean-up and reassembly

    All the loose walnut shell particles and carbon debris from the ports and surrounding areas are vacuumed before reassembling the engine and reconnecting the various sensors, vacuum lines, and electrical connections.

  • Hydrogen carbon cleaning

    A hydrogen carbon clean of your engine will be performed to maximise the quality of our treatment.

Supreme spa care for all your engines

Walnut blasting carbon clean is a mechanical engine cleaning process designed to address carbon build-up on the intake valves of direct injection engines. Fuel takes a direct route into the combustion chamber, bypassing the intake valves. This efficiency comes at a cost, as the absence of fuel bathing the valves can lead to carbon build-up over time.

Having these parts blocked by the carbon build-up is like trying to run with a blocked nose, a very straining effort for your car.

Walnut blasting rejuvenates the engine's airflow and optimises combustion.

Typical symptoms of carbon build-up in the intake valves include:

  • Lack of power
  • Misfiring
  • Hesitation
  • Thirsty Engine

Some mechanics may mistake these for being a spark fuel compression or vacuum problem, when in fact your engine’s intake valves just need a good reliable clean.
