I am glad the information was helpfull. And yes, removing the oil cap would also give you the same results. If it is not covered under warranty then at least you know now it is the oil trap box that is making the noise. If you do the repair yourself, make sure you reset the fuel trim adaptations or the fuel trim code will return. Usually unplugging the ecm will do that. Well keep me posted.
