I took my smokey Mitsubishi Legnum VR-4 down a really long hill. One which was so long that it enabled me to drive at 90km/m for several minutes with my foot off the gas. When I finally applied gas at the bottom of the hill a big plume of white smoke came out the exhaust. That's a sure sign the turbo seals are failing, right?

I'd be pointing the finger at valve guides and valve seals first.

Fair point; I'd like to see if it smokes under sustained load (i.e. up a long up hill) or on a trailing throttle (i.e.down a long up hill off the throttle) or after idling for a while. All easy stuff for a better diagnosis.

a smokey mitsi. theres something new! not! haha yes 90% its the valve guide seals. god only knows why mitsi continued to use sub par materials for thier seals even after YEARS of smoking cars.

Could be brake fluid being drawn into the inlet manifold then the combustion chambers due to a faulty leaking brake master cylinder/booster unit, via the vac hose from booster to inlet manifold? White smoke might suggest that .

is the smoke white or distinctly blue?
I would pull the turbo inlet and outlet hose and inspect for oil residue as well as pull one of the down pipes and check for oil residue there too.
