My car is fine most of the time, but once I shut it down and turn it on quickly after a couple minutes (like to pump gas) and drive away, at the next stop light (very close to the gas station), there will be a huge blue cloud of smoke coming out of the exhaust, then it goes away completely until the next time I pump gas again. It doesn't happen every time tho, and if I keep driving instead of getting stuck at the light close to the station, there will be no smoke. My friend said it could be blowby. Or maybe this is the PCV thing? but my car idles fine and everything, only happens when shut off/turn on quickly and drive to a stop nearby.

Also found a very slow oil leak at the band holding the hot and cold side of the upgraded hybrid turbo. Like a drop or 2 of oil on the ground every 500 miles. Oil lines look fine.

Anyone has any suggestions of the causes of those 2 issues and if they are related?
