Usually if the valve seals are bad the motor will smoke at start up and idle. During acceleration it can be rings or turbo seals. Not sure what it means when its only in decel.

You have 3 culprits:turbo, valve stem seals, or rings. I would pull the turbo and start from there. Once the turbo is off, pull the manifold and look inside exhaust ports on the head for excessive oil build up. There really isent a 100% proven way to tell what is wrong by when the car is smoking.

Run a compression check and see about the rings.
