extending the slobber tube
we have an FL-60 Sport Chassis, and the refurbished (whatever that really means) CAT 3126b motor, and it's starting to blow some smoke out the slobber tube, and it's getting the underside a bit oily, ...

First, refurbished means just that, the engine was refurbished, meaning rebuilt. It may have been the original engine (unlikely but possible just due to the time to have it done) or it was an engine rebuilt by a diesel rebuilder just waiting for a new home.
Second, a slobber tube does just that - slobber out a little oil and oil vapors that could look like light smoke. The smoke with oil vapors, unless extended, gets sucked into the front side of the radiator and blown through it sticking to the radiator fins which clog up with the dust and dirt also sucked through the radiator.
Third, your engine has always produced some smoky vapor. Whether it's excessive or not, only a good diesel shop will be able to tell you. Whether it's excessive or not you should still extend the tube so the oil vapors do not go into the radiator fins. Take it to a Freightliner shop and have them take a look at it.
