SR puts out blue/black smoke. Help!!!

[drifter808]

I have been driving my SR redtop for about 3 months now. I have just recently started to get some smoke out of my exhaust. When im driving i don't notice any smoke although there probably is just cant see it. When i do notice it is when im done driving it and the turbo timer is running, some smoke is coming out of the exhaust. It used to only do it once in awhile and thought it was just normal cause i only noticed it after i removed my catalytic converter. I has been doing it more though and it is causing concern for me cause im trying to sell it right now and i dont want it to be smoking.

If anyone has any ideas as to what this could be please post. I need to get this fixed. I have searched but alot of the smoking problems were white smoke, not blue/black smoke.

Thanks in advance, if you post.
