Thanks Mike, I thought you would be the person to reply. Upon closer inspection there is a hose on either side that runs the length of the cam cover, looks like a crankcase ventilation hose of some sort so that's squared away. I don't appear to have an air pump, I checked and all I have is the alternator on the left side, and the ac pump down the bottom right and what I assume is the power steering pump above it. I couldn't see the air pump or the self levelling pump either. Any thoughts?
