As long as you're not losing water & the engine runs OK it's unlikely to be the head gasket. I am assuming the smoke was coming from the left exhaust pipe? If not, & it was just smoking in the general area of the rear cylinder then check that no wiring or anything has come into contact with something hot & melted. I was in heavy traffic once in the rain & noticed smoke. Was alarmed at first until I noticed my left leg of my waterproof pants was melting against the heat shield on the left pipe. Smelled awful & ruined the pants too!
