What is a Carbon Cleaning Service and Why Do I Need It For My Late Model European Vehicle?
Direct-injection technology allows gasoline engines to be more fuel efficient. More power, better emissions controls, and most important, increased fuel economy. These benefits come with some drawbacks. One is carbon build-up around the valves will occur. This build-up affects the air intake system and causes many symptoms. Some of these are loss of power, misfiring, rough idle, and poor fuel economy. The worse part is when the problem is intermittent, and most shops miss-diagnose the vehicle because the do not look at the valves using a borescope.

At Dealer Service Alternative we recommend to our clients to do carbon cleaning service to their vehicle engines regularly. Every 70,000 miles is, in our opinion the most you should wait to perform this service. We like to see this service done every 50,000 miles before it causes any problems.
How do we perform this service?
Walnut shells are softer than the alloys used on the head or valves causing no damaged at all. It is the recommended procedure by several manufacturers. We perform this service one port at the time, using a combination of walnut shell blasting and solvents. The intake manifold is removed, we rotate the engine to close the valves on the cylinder being cleaned and the ports are blasted with walnut shells and solvent with soft brushing is used to remove more stubborn build up. This is the only way we have found to leave the ports completely clean.
