ok, so heres my situation, my zc is smoking now more than before. backstory, car died on me, it was the dizzy, while i was waiting for the new one, i swapped out new tstat and cleaned the pcv valve. i would have bought a new one but cleaned it instead. there was gunk all up in there and when i was done the piece inside actually was now moving. since this was blocked for who knows how long, could it be just burning the residual left in the line? its blueish smoke. i was thinking it was valve seals and still do along with possibility of rings but ive yet to do a compression/leakdown test pending right tools. any advice?
