94 850 turbo smoking white smoke 850 1994

I have a 94 850 turbo that is smoking white smoke out of the tailpipe only at idle and deceleration. I took it to my Volvo mechanic and he diagnosed it as 1 of 2 things. 1. valve seals need to be replace $1,ooo bucks or the turbo needs replaceing (worn seals) $ 1,500 bucks. I could not decide if wanted to spend that kind of money on the car or not. I brought the car home and at the advice of a buddy of mine I added a qaurt of STP no smoke additive, I let the car run at idle for about 30 minutes and drove the car around for a while and still no smoke. Does this mean since this stopped the smoke temporarily that it is probably the valve seals that are bad and the additive is just thickening the oil so it is not getting past the valve seals and being burnt and sent out of the tailpipe. I do know the additive is not a permanent fix for the problem.
Thanks
