Cross your fingers and maybe the Roadster Gods will smile on you
by giving you an easy fix. Couple of questions, though:
1) Did you do a wet and dry compression test? If #3 measures much
higher with a wet test, I'm afraid it's more than valve seals
2) Does it smoke all the time, or predominantly a) at startup, and
b) deceleration (moving at speed, foot off gas) i.e. high intake
vacuum conditions? These conditions are when you'll usually notice
bad stem seals in action.
