Hey Team Our e87 04 120i has just majorly started smoking (blue/kinda white) on start up and while driving. Engine check light comes on and starts flashing, once the car is in park and idling the check light goes away. But if we leave it for a day of two it stops doing either.. No fault codes are staying up and every time we have taken it in it has stopped and ran fine. Its not using any water/no bubbles in radiator. Oil doesn't look milky from first inspection. Any Ideas? Was leaning towards valve steams but also possible piston ring failure? No major knocking sounds but is down on power even when its not smoking. It did start 'pinging' today how ever on start up... Am not driving the car atm until we have an idea of what is wrong.. Cheers Ace
