Pulled my air intake to do a brief inspection on my throttle body as it's over the 199,000 mark and it has had hardy many gdi cleanings since I put on the induction kit. Seems that the pcv valve and everything is working. Running good fuel, occasionally a pea fuel based cleaner and four ounces of gumout multitune in the crankcase right before a oil change. NO oil,gunk,etc found on throttle. I did do a GDi throttle cleaning today which threw a bunch of codes lol. Literally no smoke after so that tells me whatever is being done so far has worked.
