[QUOTE="69ST, post: 58311, member: 5"] The smoking could be a leaky valve seal, or seals. You should plan on valve seal replacement with a rebuild anyway. If the cylinder walls look good, it might make sense to try new valve seal(s) alone and see what happens. Take a look at your intake port. If it's black, chances are good that the intake valve is "mushroomed" and should be replaced. That won't make the engine smoke, but indicates reversion, from pressurized gases leaking past the intake valve, into the intake port which won't help performance. [/QUOTE]
