Need more info on the milage and so on. Pull off pcv hose and block off on the intake side. See what that does. Not a sweet smell is it?

Starting to sound like coolant not oil. Been adding antifreeze?

You just answered the problem. Smells like boiling water. Same on the rear tailpipe.?

A good 5yr coolant. And stay with the same kind. Some will say hoat. But As long as you use one product and don't mix with other brands It's all good. Use distilled water to keep from building mineral deposits in the block and head.

In the turbo there is a shaft that connects the intake/compressor side to the exhaust/ impeller side. That shaft has an oil lubed bearing and some seals that can leak oil into the exhaust and out the tailpipe when they fail. You might notice that the "smoke" is slightly blue-ish if it's oil and a more pure white if it's coolant. The difference is very subtle, though, and hard to tell. Maybe you can check right after a drive for residue at the tailpipe to see if it's wet or oily.

Why is the hose missing for the PCV system? Is the fitting on the back of the intake manifold plugged or capped where the hose is supposed to connect? Because if it isn't, you have a massive boost/vacuum leak. The PCV valve could be stuck open, acting as a breather or it could be stuck shut dumping oil vapors into your air box and intake, pre-turbo. The hose piece is $5 and 5 minutes to replace. It sounds to me like maintenance has been pretty spotty so It would probably be a good idea to get a new PCV valve while you're at it.
