So, my 6000 my scheduled maintenance is fast approaching. (appt this saturday) The only issue that I have experience in these 6000 miles is blue smoke upon start up, several times a week. I understand that this may be a symptom of burning oil. I have not been able to monitor if oil has been burnt, as the vehicle was over filled from the factory and any amount burnt was not obvious. I do have a video to show the tech. Am I correct that they should be able to check the PCV valve for the presence of oil, also. Anything else that I should make sure is checked?
