Default 05 STi white smoke, burning oil, condensation

2005 STI with ~86k. At idle, whether its cold or hot, puffs white smoke and creates a lot of water at the end of the exhaust. No smell or color to it. Figuring something was wrong I checked the oil and in about 1000 miles burned a quart. I read on here that is somewhat normal. I pulled the turbo and it was completely dry, no oil. My next step was to change the oil and brand. So I swapped Mobil 1 for amsoil. Haven't driven the car much since the change, not sure if it is still burning, but still puffing smoke. After that had compression and leak down test and came back perfect. Then I installed Crawford AOS V2. I just ran the car for the first time yesterday and noticed that one of the lines to the AOS is pure condensation and water droplets. Is this normal?

Also, while changing out turbo inlet pipes I noticed I had a lot of oil in the intake manifold. And with the heat on, first 5 minutes of driving there is a bad burning oil smell in the cabin, but then goes away. I most likely have a feeling that the motor is on its way out, but trying to see if someone else had any similar experiences.

Car has full exhaust, CAI intake, inlet tube, and a pro tune.

No CELS. No misfiring. Idles fine. I could pull a data log on my AP to really find out, but not really sure on how to do it and upload it.

No other signs of that though. Who knows.

What I'm really trying to figure out is all the condensation. Any ideas?

I agree could be a head gasket issues, how does your coolant look?

I had drained some of it out to do a few things on the car, and it came out fine. I just added probably a gallon or little less of Subaru coolant.

How long have you had the car? Do you have catless exhaust? I'm assuming when you say "hot or cold" you mean the engine, and not ambient temperature right? A catless exhaust usually does make more visible exhaust vapor than catted. Is it possible that that's what you are seeing?
