Default Where is this smoke coming from!

I know this isn't a great deal of information but is anyone able to help diagnose?

It happens obviously allot more when the car is warmed up and it seems to be coming from the left hand side of the engine bay around the turbo but not actually the turbo.. will include a video shortly once it's uploaded to youtube.

White smoke usually denotes a coolant leak check the area around your water pump.

It looks more of an oil leak making it's way to the exhaust manifold. In the end of your video is that the alternator? Check for valve cover leaks in that area uptop if it's dripping, and pooling at the bottom. I had a friend yesterday send me a quote. That her Hyundai is leaking oil from her upper pan gasket, and valve covers. I told her probably due to the fact that her PCV is probably not functioning well.

The coolant would show if it was leaking. It would be a pink crust, and probably smell sweet. Assuming you're using OEM coolant. If the smoke smells more like oil it will probably be more of a strong smell.

If you can get some degreaser and clean the area well, and check after it has dried. Avoid getting degreaser on electrical connectors, and especially the alternator in that area.
