Anybody have blue smoke?
I just bought a 2016 Mustang GT about 3.5 weeks ago. It has just over 1250 miles on it (had 570 on it when I bought it). Right now at every start up it is rolling blue smoke out of only the left side exhaust. Took it to ford they couldn't find a problem and told me it was fine. My guess is that a valve is leaking. Has anybody noticed this with their mustang? Or is this normal break in period?

Does it do this at "every" start? I mean, you drive it 100 miles, park and shut it off, then restart after two minutes and it still does it? Or is it after the car has been sitting for a while?
I wouldn't think it would be a valve problem, per say. If you had a valve leaking any at all, that cylinder would be down on compression. If that were bad enough, you'd feel it in how the engine was running. Blue smoke is usually oil related. I've seen valve oil seals leak that allows oil to trickle into the combustion chamber. I've also seen issues with oil rings on the pistons that allow it to draw oil into the combustion chamber.
570 miles seems like a lot of miles on a new car. Was it a demonstrator? Those cars don't usually have an easy life. I'd be questioning how it was driven while it was in the break-in period. At 1250, the break-in is pretty much over with by now. I don't doubt the dealer isn't finding anything specific wrong at this point. If it's running right, I'd just keep a close eye on the oil levels. If it's using oil excessively, then you'll have a claim. If not, and it's performing properly otherwise, I'd just drive it and not worry about it.
Good luck,
Steve R.
