My 2001 Z71 has had the "Check Engine Oil Level" light come on at 3000 and 6000 miles. I thought maybe that was the oil change warning but after talking to the dealership realized it was consuming oil. They decided to change the oil and do an oil consumption test. 900 miles later it's asking for oil again. The service tech said it was probably the PCV valve and couldn't get another part from GM without first documenting the issue. At one point he climbed up onto the engine and pulled the valve and said he saw oil so he was positive that this was the problem. I'm now sitting on 13k miles but they still haven't gotten the new part in yet. Has anyone else experienced this? Are they blowing smoke? So far this is the only problem I've faced with my truck other than the little "chirp" I hear when taking off. (Does anyone know what that is?) Thanks.
