Are you suspecting that I may be getting blowby past the piston rings? I kinda figured the smoking is mostly because of the valve guide stems since it stops after a minute or two...

Well you stated that the inter-cooling piping is dry. To produce smoke you would need quite a bit of oil in the inter-cooler and charge-pipe. It's rare to have a guide/seal issue but it's possible. It does happen.
Are the plugs black/ashy from burnt oil?
Oil can only get into the combustion chamber so many ways. Rings, guides, or the charge pipe/intake manifold (blow-by or turbo).
