Low compression and smoke would suggest blow-by, i.e. that the piston rings and/or the liners are worn out. See if you have oil mist coming out of the crankcase vent. You could also be unlucky so all the ring gaps lined up, I have heard about this problem on VW flat-fours.

Another reason for smoke just as it gets warm is that the exhaust side valve cover is leaking oil down on the headers. The cooling fan and the wind speed will carry the smoke under the car and towards the rear.
