Excessive carbon buildup will cause a reduction of airflow as well as smooth airflow into the combustion chamber. Some of the common byproducts of this is reduced fuel mileage, reduced engine power, misfires, and poor idle. When performing a carbon cleaning, you will want to perform the work on the valves that are closed (rotate engine as you go to be able to clean all valve pockets). Fill the valve pocket in the head with the cleaning solution and let it sit for a few hours. After the pocket has been soaking in solution, you will want to use the supplied brush to scrub the pocket clean (insert the brush into a standard drill for optimal performance). Once you have finished with the brush, use the supplied picks to get the areas behind the valves that could not be reached with the brush. NOTE: During this time would be a great time to install intake spacers if they are available for your engine. Please go back one section to see if they are available for your car. NOTE: If you need cleaning solution for the job, we have some available! Please go back one section to grab the cleaning solution. NOTE: Clean with caution. You are dealing with the cylinder head valves which are a crucial part of the engine. Letting the solution soak for a few hours allows you to gently clean the valve pockets.
