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?

Hi there,

Thank you for the donation,

You may be suffering a bit of blow by, I would start with a leak down test to determine the condition of the lower end, and if you are using a synth oil try changing to a mineral oil, this may help as well, start here.
