Well, my 06 GT spit out some blue smoke the other day when I fired her up which usually means burning oil. Well, I took her into the dealer and they told me that I had a bad valve stem seal and they would need to keep my car for 2-3 days to fix it. I'm just wondering if anyone else has had this problem b/c I didn't see it anywhere else on here. Is this a common thing for our cars? I can't believe it. My first new car w/ barely 8K miles and in the shop already! Ahhh!!!!!!!!!

is it completely stock?

Yeah, the only thing I've done is change out the exhaust. My next mod is a CAI, but not yet. So it's completely stock right now.

So I'm the only one who has had this problem????

Once in a while I might notice some blue smoke (very little) at first start-up, but nothing to really worry about IMO. My oil level doesn't really drop between oil changes.

Mine spit out a good amount of blue smoke the other day. I have been checking the oil as well and it hasn't changed, but the blue smoke has to go! I don't want it to get worse.

There are two ways for the dealer to address this. Normal oil consumption is anything up to and including 1qt per 1500 miles. This means that it is completely normal if you have to add a quart between oil changes...... yeah, I know........but its the spec, so what can you do?

Exhaust smoke is actually a different area. You can have excessive tailpipe smoke and no noticeable oil consumption. If I were the tech working on your vehicle, I would pull the exhaust manifold on the bank that has the most smoke. This would be done AFTER I confimed that the pcv system wasn't full of oil because you may just have a bad valve cover baffle. If there is oil residue in the manifold, replace the exhaust valve stem seals. Otherwise, if a leakdown test showed the rings sealed well, the only other place where oil could enter the combustion chamber would be the intake valve stem seals - which don't leak often. The PCV or exhaust valve seals are the most likely. PCV because its a tube from the valvetrain (oily) to the intake. Exhaust valves because they run much hotter than intake valves and consequently may trash seals faster.
Now, you may not care less how the guy fixes it - just that it is fixed right? But consider the fact that if other mustangs on the lot have a puff of smoke when he starts them up, the dealer may consider the issue a characteristic. (if this is hard to swallow, be glad you don't own a lightning, cobra, marauder or mach) The explaination for that comment is another paragraph within itself.........

How does everyone see this smoke when you start the car? i'm always inside the car and I don't see anything.

Mine does it but I thought the last discussion about it determined that it was "normal" for these cars. Mine only does it after sitting a couple of days.
