-2002' V70 84k and I have white smoke coming from the tailpipe, specifically at a stop. The smoke will come out of the dipstick if I pull it at idle. Based on what I have read on the forum I think I should do the PCV system. My first thought is it could be the sign of a bad turbo. The car has runs a bit rough at idle stop in gear. In neutral the car doesn't have a rough idle. At speed the car seems to run fine.
Any thoughts?

 

 

Update -
The white smoke stopped on it's own. I let the car sits a few days . after reading up on possible causes, I did the glove test on the oil fill cap, and co-incidentally noticed no smoke. The glove showed noticeable vacuum. It's very strange because the problem seemed very serious -I'm talking a lot of smoke - like envelops the car at a stop light.
But I ordered the PVC trap & hoses, and spent a day putting it in. Good thing because the trap was totally plugged and filled with liquid. There was water mixed in, the emulsified creamy light brown mix. The connections to the block were also plugged solid.
The car seams to run fine now.
