What is an engine carbon clean?

If your car is dropping in performance, there is a chance that the engine requires an engine carbon clean. Most cars run fine in the first few years, but may require attention after completing around 60,000 miles. A carbon cleaning is recommended as a way of restoring some of that lost performance, or as a way of helping your car pass the emissions part of the MOT test.

Engine carbon cleaning usually refers to the process of removing carbon deposits. Engine carbon cleaning involves removing engine components and giving them a thorough clean, by using solvents or a blasting method. It is often done as a specialist job only by those garages that have bought specialist equipment. The mechanic will physically clean the intake manifold, intake ports, carbon on valves, top of head and top of piston.

Which engine carbon clean service do you need?

There are several different services which are offered, either by mobile operators or a network of garages who have bought the equipment to complete an engine carbon clean. There are three ways specialists can do an engine carbon cleaning service detailed below.

Engine carbon pour-in treatment

A pour in treatment uses chemicals to help dissolve the carbon deposits in your engine. It is the simplest method, as it is a simple pour-in treatment which is added to the fuel in your car, so this service will be the least expensive.

Engine carbon clean injecting super-refined gas into engine

A superior cleaning service is when the specialist taps into the fuel system and injects super-refined gas to the engine. This in turn makes the engine burn extremely hot which is to help clean the components. Often you will find noticeable soot expelled from the exhaust after this treatment.

Engine carbon clean - traditional method

The most thorough engine carbon clean is done by using the traditional method, where a technician will remove engine components and clean them by using solvents or blasting them. Sometimes walnut shells are used so that the texture can help to remove carbon without harming engine parts.
