Hi there. By looking at the photos that you have provided is shows that the PCV (positive crankcase ventilation) valve is blowing by and causing engine oil to go through the PCV tube. Since your engine has a turbo on it, I recommend replacing the PCV valve and clean out the tube. Then every time you have an oil change, I recommend replacing the PCV valve to prevent any more oil consumption and leakage. If you need further assistance with the oil getting on the air filter, then seek out a professional, such as one from Your Mechanic, to help you.

Q: Engine revs high while idling and then drops about 1000rpms every half second or so.

My guess is that the unstable idle and unintended acceleration is due to a faulty idle air control valve (IAC). The powertrain control module (PCM) uses the idle air control valve to divert air around the throttle. Increasing the amount...
