if you are getting blue smoke all the time it's probably your rings, does it get a lot of idle time? if it does you might be able to reseat the rings by covering part or all of the radiator and put it on a hard pull for a while. remember to watch your temp gauge though. you should be ok up to about 260 degrees F you would need to keep it above 230 degrees for about an hour. if you have a LOT of miles on the engine though you'd be better off with new rings and sleeves. if you only get blue smoke from start up to operating temp. it probably is your valve seals and guides.
