Q: Car spits out white smoke when started after sitting for a short time

asked by on

We've changed a few things that various mechanics have suggested. Every time the car is started, the muffler spits out a smelly white-blueish smoke, that lasts for probably a whole minute or so (never counted). It doesn't happen as bad if the car was driven super recently but anytime it sits for more than an hour or so, the smoking regenerates itself.
