If the engine needs a rebuild and you plan to junk it, let me know. I might be interested.

There are a few things that happened from what I can piece together right now.
Typical oil burning in turbo car + bad PCV valve causing valve cover gasket seep + my neglect. I really don't know at this point though. I don't think the tune had anything to do with it because at the boost I was running and what my wideband was showing, it was a fine AFR. It might be something else too I don't know yet. Ideally I don't want to drop an engine in so if it's just a bearing or just a rod, I might be able to get away with a cheaper repair. If I can build the engine for the same price as swapping in a stock one that's definitely the route I'm going, not to run more power but for safety's sake.

I don't understand it too. ehow.com says the gasket leak causes the engine to burn oil.

It makes oil leak. Bad tube seals would make it burn. Tube seals come with the valve cover most times and go around the spark plug wells.

Yes. Even with stock timing, a safe tune should be from 11.0-12 at the most. Anything higher than that is asking for trouble. Especially when you start messing with timing or you get a boost spike or excessive heat.
12+ is too high for boost. Especially above stock. 12.8-13 is crazy lean

Then that would be my fault on cranking it too high. We'll see what happens. I was very disappointed at first, but I figure if my block and crank are in good shape I'll at least have a platform to start on. Who knows, I might even find a cheapie used engine..either way I can't see myself selling the car, probably the thing to do now is to finish cleaning out the garage, roll it in, and start working little by little.

A guy on the MSM forum had the same thing when he bought his car and he said it was one of the bearings. I don't know if that's going to make it more or less expensive for me but definitely not driving it anymore so it doens't sieze completely. I really think this started pre-flash I just didn't notice it.

I could go back and quote where I said get a real tune, but you live and learn, now without someone hearing the motor and tearing it down don't take what the guy on a forum says. Get a wooden dowel and listen to the motor to see if you can hear exactly where the noise is.

It ran fine and made no noise at 10psi and 12.5AFR I know that because I put about 100 hard miles on it 2 nights ago. Started it up at home yesterday (no knocking) and I decided to turn the boost up to see what the real AFR were at 11psi (because my wideband was reading much better than the one from the dyno runs), guess I got too greedy. I only heard the knocking when I started the car up to go to lunch so it must have been the ride in that finally did it. My lesson to learn not to beat the balls off a car that's not completely tuned yet.
Until my buddy takes the car for the day and diagnoses it, I'll refrain from posting here.

There is a way to check if its the bearing, pull the plug wire, but it's hard to do on my setup because I have 2 coilpacks and 2 wires, and the way they are configured its impossible to pull one at a time.

This is what it sounds like when its first started, once it warms up you can't hear the knock at all, only a little if you listen for it through a small exhaust leak, nothing under the hood.

Good god,drop the pan and take a gander under there before you do serious damage...
For serious check all your pulleys for play,including the waterpump. If everything is tight then its time to check the bottom end
