One reason the 3208 smokes a lot, particularly on start up, is the pistons are made in an oval shape. As the piston warms up, it rounds itself out, fills the cylinder all the way up, and then increases the compression thereby creating the optimum burn.
When a 3208 gets older and the pistons start to get a little sloppy in the holes, the smoking gets a progressively worse because you never get full compression.
As to the white smoke coming out of the blowby, I am thinking you most likely have a problem somewhere inside. I am thinking you have lost the rings on a piston or you have a hole burned through a piston. In any case, you are getting some of your compression going into your crankcase.
I am thinking that you may have run the fuel mix a little lean if you have been using veggie oil. If that is the case, your head temps may be running a lot hotter than you should be. If your head temps are running hot, you could have burned a hole in a piston.
As to the turbo, why in the world wouldn't you want a turbo? Particularly in a Gillig? Not only does the turbo motor produce about 20% more HP and torque but you don't lose nearly as much go as you go uphill. a turbo motor is going to use less fuel to do the identical amount of work.
If you decide you need engine work, it will be a lot easier and less expensive to purchase an engine in a box and swap them out. Doing an inframe on a 3208 is a real loser of a propisition.
Good luck.
