I have replaced just about everything on my e39 m62tu touring including ccv, maf, plugs, 3 coils, spark plug boots, intake gaskets, throttle body gaskets, 1-4 cps. Just replaced valley pan gasket and before I replaced it no smoke and car was running very poorly. After replacing valley pan and #7 and #1 coil car runs like brand new but now I get smoke on startup and when accelerating if I have been idling for a bit. pulled codes with my peak scanner and I get code 50 secondary air system 1-4, code 51 secondary air system 5-8 and 2d catalyst eff 5-8. Could there be any reason other than my ccv for the smoke?
