pulls the plugs out and see if you have any oil deposit.
In most case you probably have a old worn out oil seal in your turbo.
Be sure you run a oil restrictor too, IIRC, for journal bearing, use 0.065" orifice restrictor.

Mine smokes too after a couple of hard run, I know its my turbo, not my engine

[Jonathan Rivera]

plugs are fine . were would you install the oil ristrictor?

[gunluvS14]

oil supply of course.
JGS tool sells one that screw into the fitting

from the block to the line or from the line to turbo?

[drifter_for_life06]

line to turbo i believe....it might not matter

if you didnt know blue is oil white is coolant, which could mean a leaking hg

[Jonathan Rivera]

but if it was a head gasket wouldnt it smoke almost all the time like warm up ,and leave trail of smoke when acclerated on the freeway?
