Alfa Brera 2.2 JTS WALNUT BLASTING

In this video we do a carbon cleaning on the intake valves of my 2.2 JTS engine. With direct injection the intake valves can get clogged overtime due to carbon deposits and crankcase gasses sticking to the valves. If this get worse the engine can start running rich, rough idle, misfire and loose performance and fuel economy. So to keep the engine of my Brera healthy, a carbon cleaning is performed in ways of walnut blasting as a preliminary maintenance step.
