bad rings will cause smoke all the time,idle,acceleration ect,

its turbo related,the back pressure suck the oil from the turbine shaft,you must have a little shaft play ( side to side) that cause oil leak on decel, it wont cause any lost in performance,but cloud of smoke,turbo rebuilt or new one are required
