Engine flushing is a procedure that is used to clean the engine of sludge and other elements that build up in various parts of the machinery over time. The main purpose of this procedure is to prolong the life of the engine. By flushing an engine periodically, the internal components of the engine remain relatively clean and thus perform at optimum levels. The process employed to flush an engine is somewhat similar to transmission flushing. With a transmission flush, the usual flow of fluid through the mechanism is used to push old fluid and various contaminants out of the system via the drain plug. With an engine flush, the cleansing chemicals are introduced and allowed to circulate through the engine, following the same flow pattern as the oil that lubricates the engine components. The chemicals eventually make their way to the oil pan, where the chemicals and the sludge they have removed deposit.
