Intermittent Oil Leak?

I found the source of the leak, it's at the base of the combi valve tube where it bolts to the block. It wasn't seated properly (you're working blind down there, even with a mirror.) Fine and dandy, except that I stripped the torx-type bolt trying to tighten everything down.
So I'm ordering the combi valve block-off plates from 034 Motorsports. http://www.034motorsport.com/engine-...8-p-21816.html
Now I'll have the bolts I need, and the plates to remove the system when it fails (the pump is already howling bloody murder on cold startup.)

The gasket is part # 078 131 120 D
Yep, I think good high heat gasket maker would do the job.

Finally fixed.
The problem turned out to be this: there is a small bracket holding another line (to what I don't know). When I reassembled everything, this bracket ended up between the mounting tube and the engine block, as opposed to on top of the tube with the mounting bolt threaded through it (so that the bracket acts like a washer, you dig?)
Anyway, I got everything squared away and swapped the OE torx 30 M6x20 bolts with standard head ones, and treated everything to some gasket maker to boot.
Thanks everyone for your help with pictures, diagrams, ideas and suggestions.
AR forum FTW. <--- (are people still saying that?)

No more oil smoke, but...
There is still a persistent (small) leak somewhere. Doing the oil change on the weekend I saw the same little drip of oil coming from the passenger side of the oil pan. Here's a pic form the summer, looks the same now: 
So it's not the cam cap, cam adjuster seal, or valve cover gasket. What else could it be?

I still have the a similar leak on mine after doing the cam caps, valve cover and cam tensioner seals too. I think mine is leaking from the oil supply lines to the turbos.
I'm just not worried about mine at this point.

Let us know what you find. I wouldn't mind putting a stop to my leak as well if it's easy enough. I honestly have just not looked enough into mine to know what it is for sure.

It's probably not going to be until next spring. Winter is here in the sub-Arctic and I won't be tackling anything until the snow's gone (I don't have a garage/I'm too lazy.)
