Default Oil Leak - Passenger Side Turbo. I just had valve covers, cam tensioner seal, and cam caps replaced

but I still have quite a bit of oil on my passenger side turbo and the belly pan.

What's the best way to get a look at this turbo?
Take the driver side wheel well out?
front bumper off?

When I look down the drivers side of the engine from the top I can see little plumes of smoke coming up from near the wastegate of the turbo is, but I have no idea what is leaking.

How can I get a closer look?

Here is a pic from the bottom (after I cleaned it up):

From the top:

Before I cleaned it up it looked like this:

you sure that's not just the valve cover leaking onto the exhaust manifold there?

What's the best way to get a good view of that area?

Default best view

pull the headlight, start the engine and let it idle. Get a decent flashlight and look around the bottom of the valve cover (look in from the headlight housing area)

Default Same thing happened to me the other week.....

Had the same work done and the car was still leaking quite a bit of oil. It was all over the turbo and the same places you described. Turned out to be a bad rear cam seal that was defective when they put it in.
