82 FJ 60 . I have a puff of blue smoke when I change gears . Valve seals ? Or something more serious ? Engine seems to run great .
 
Seals, rings, blow-by. You'd have to do a leak down test to help pinpoint it, but prolly just a worn engine. If you're running ok and plugs aren't fouled, enjoy!
 
Loose valve stem seals (that are old and hard as rocks) are common.
