Spirit R/T smoking under deceleration

1991 Spirit R/T. Stock turbo and engine. Doesn't smoke upon start up or while idling. Tried to pin point when smoking and seems to be doing it after accelerating and then backing off. Doesn't seem to be smoking while just cruising at a steady speed. Haven't checked plugs yet.

So bad under boost? and high vacuum?
Turbo bearing leaking?

No one else have input?

When you say after accelerating, is this after going into boost?

Yessir

Turbine shaft seal is leaking.

I will second that, sounds like turbo seals. Time for a rebuild

Thanks fellas.

not a problem,,,good luck

smokes at start up and when decelerating is classic bad valve stem seals

smokes out the entire intersection stopping traffic from all directions after you drive away is either a lifted head gasket or a bad turbo
