Diagnosis on '90 780 Burning oil... PCV? Turbo? Valve Guides? 700 1990

Sounds like a good car. Consider intake valve seals. You seem to have it covered well. Any chance the turbo seal on the exhaust side? Except you would expect smoke on start up.

I have a couple doing some light blue smoke with many more miles and have done all the good stuff as far as intake and even a rebuilt turbo, so am to intake valve seals. Just finished fabricating a tool to do this in the car, otherwise it is a remove the head thing.

Will be following this thread. Still in TX??
