Re: Blue Smoke (2.0 16valve)
I think we need to ask two very important questions before passing judgement..
Chris, what grade of oil do you use? If it is anything thinner than a 10W semi-synth then that'll be your problem. I would also advise against using fully-synth as the engine was not designed for this kind of oil; f-s oils did not come onto the scene until after the TS engine was designed.
Secondly, how many miles has your engine done?
If the engine is tired and you think you are not going to keep the car for too long and/or you will not be looking to rebuild the engine thus replacing all of the seals I would suggest you switch to a 15W-40 or 15W-50; that should solve the problem for another few years.
The reason why it is mostly smoking on trailing throttle is because of engine braking.. when the throttle is shut and the engine is still spinning, it is trying to pull in air and fuel thus causing quite a powerful vacuum; this may be sucking oil into the chamber from the intake valve guides (when these are open during the induction stroke) and or the piston rings. Chances are, the valve guides are gone as these tend to be more delicate than the piston rings.
