I recently started my car and popped my hood only to see smoke coming from the hose on the back of my valve cover by my ignitor, i know its blow by from my crank case,but! recently i put to much oil in my car while doing an oil change. could it of just purged some of the excess oil out and is burning it off? or is this a serious problem? i looked at my dipstick and theres no smoke coming from there so i dont know what to think. is this normal or something i should be worried about
