Sign of oil leak?

[BSOD2600]

This afternoon when I fired up the car, there was a cloud of blueish smoke out the exhaust. This is the first time I've ever seen smoke come from the exhaust since owning the car. Anyways after a few seconds it cleared up and I drove home. When I got home, I popped the hood and noticed there was little wisps of smoke coming from around the turbo. It wasn't frequent enough to actually see where it was coming from, but it was in that general area.

Is this a sign I've got an oil leak in the turbo or something else?

Hmm, well I drove to school again this afternoon. No smoke out of the exhaust. But on the drive, both my passenger and myself noticed a slight burning smell in the cabin. When I arrived I school, I popped the hood and didn't see any smoke around the turbo this time.

Guess it was a one time thing. Odd.

Old cars do leak a little oil from time to time. How many miles on it?

150K.

You don't think its odd though, to see a cloud of blueish smoke one day and not ever again (yet)?

I would blame the rear cam support seal. Mine would randomly spew little clouds of smoke out my hoodscoop at idle after loading the motor a while. Accompanied with the burning oil smell. Check the top of your uppipe towards the back of the head, you should see where it was/is dripping. Here are some pictures if it helps
