120psi is low. Blue smoke is either the rings or the turbo. Put a spoonful of oil into the cylinders and see if the pressure goes up to 160psi where it is supposed to be.

is it overfilled?if not you have a lot of blow-by.time for a rebuild or replacement.if i decide to replace mine i could sell it to ya...btw...how many miles on your engine? was it mantained regularly?

A leakdown test is a better indication of what shape your rings are in than using oil.

itll always raise with pouring oil in.. the question is how much (and how much oil you put it too)

yea a leakdown test will give a better answer as to the engine health

120 is REALLY low. it should be 165-180

always gotta comment and say something is better or whatnot...either way wore out is wore out...if it's burning oil and has low compression,uh,that might be a sign,ya think?
