I’m having this issue with my s650 since the day I bought it. It’s the exact same issues you described with the blue/white smoke after warming the car up and letting it sit for about an hour.
How did you get your local dealer to buy the car back even after the long block was replaced?I’ve got a 4 week wait for the service department and I wanted to get a head start lol

@wilkinda65 ..... sorry to hear this. The guys are 99% likely right with valve seals. Bluish smoke is definitely oil. Likely as simple as a miss formed valve stem seal at a 12:1 compression ratio this would smoke. In simpler days pulling plugs would confirm but coil packs are more of a pain to do and you shouldn't do that any way with your warranty. Your dealer will fix this.

I got 760miles and it shoots out a puff and it’s stinky on the initial cold startup. Then it carry on to its normal condensation.

Majority of cold starts it shoots out a puff on the initial start up then goes away, a couple seconds later it carry on to its normal condensation. Sometimes the puff has more smoke sometimes it’s minimal like the video.

that doesn’t look out of the ordinary at all. Smoke would smoke longer than that .5 sec puff of most likely condensation

Condensation does not burn blue.

Some of these motors have obvious oil seal issues. There is a 2024 vendor car around the net, that I won't name, that is BURNING oil.

The more smoke happens randomly. This video is after the car sits for 4hours after driven. When I got the car in October 2024, even on 80degrees weather the car will shoot out a puff after it’s been sitting for a few hours.

I still don’t see an issue man. But if you are concerned take it in and see what they say.
