So what your seeing is normal. The longer the car runs and the warmer the ambient air temp the less you will pull water vapor, but in below freezing temps there is a ton of water condensation into the crankcase and when up to operating temp this flashes off as steam that is then pulled out and through the can. Nothing is wrong w/the car as this is never seen w/out a catchcan.  |
Then everyone should have one.
Sure wished I had thought to take a picture of my last 2k miles that I poured in the recycle jug yesterday.
