Coolant and possible oil leak

UPDATE WITH PICS!
Alright, so I put the car in service position (in under an hour I might add
) and I don't think its the water pump seal.

You can see here that the drips seem to be coming from or around the thermostat housing. Now I put in a new o-ring when I did the timing belt, and it hasn't leaked for the several months since then. Lucky for me there are about 4 other hose connections at that point, making it very difficult to pinpoint the source. Any ideas about where to go from here? I'm going to feel around with clean hands and try to find a wet spot, but my hopes aren't high. Starting to feel like my best bet is just to let it get worse, so it becomes more evident where the leak is.

I know its kind of hard to see, but the top of the tape is where the coolant was when I left it, and the current level is how much there is 24 hours later. Its a pretty slow leak, but it will certainly rack up a coolant bill.

A bit unrelated, I know our turbos spit a little oil in the the inter cooler pipe normally. Last time I opened up the pipe in January, I found metal shards and some oil, which I hoped was from the previous owner's bad turbo. I cleaned out the pipe then and I dont think I saw any metal this time. I'm going to check shaft play tomorrow on the turbo. I did find that my splitter valve seems to spit some oil, is this normal? I've switched it to full recirc just to see if the engine runs better.

Thanks again for all your knowledge! Looking forward to talking big turbo with you guys, hopefully this summer!
