Cleaning motor
It is possible to power wash one of the new 5.3's without screwing things up? It is pretty clean now would just like to freshen it up.

Re: Cleaning motor
Be careful... There are Two knock sensors in valley under the Intake manifold that will throw a Service Engine line if they get wet and short out... Found out the hard way on mine... to repair you must pull intake and replace harness and two sensors and re-seal.
