If the smoke (assumed o be there) is much less when running under load, and gets worse idling or going down hill, it is probably valve guides. With good compression, putting seals on the stems under the retainers is cheap and simple. Even umbrella seals will make a drastic difference. Perfect Circle style seals are better. I use a 2 foot length of cotton rope pushed in through the spark plug hole (with some hanging out) then turn the engine by hand till the rope holds the valves shut. (assumes the rocker has been removed and the pushrods pulled out to allow removal of the keepers and retainers/springs. The seals are installed and the retainer/keepers put back on. The seals keep all but a small amount of oil from being sucked past the guides. If the engine smokes under load, it is going to take additional work to diagnose (possibly rebuild) and cure the problem. Synthetic diesel grade oil 15-40 can also be a partial solution. Jim
