About a qt. A fill up(once a week). Not leaking out, not in antifreeze, not blowing any smoke. No trouble codes. When I cleaned the throttle body, did notice build up of carbon in the wholes. Tail pipe also building up. PCV valve constantly rattles. I'm stumped, could the oil be blowing back up the intake? Why?
