Well i did a boost test...it was holdin NO pressure. I could not hear a leak at all. This was because the air was flowing immediatly out of the turbo outlet while i was pumping. The way i figured it out was i hooked a smoke machine up to the boost leak tester.....smoke was pouring out inbetween the turbo and the LICP. I took the lower LICP off to find nearly half of my gasket missing. Im assuming this was the problem. Ill post once i get the gasket and have everything back together.

Well no one with in a resonable amount of distance has the turbo to LICP gasket so i had to order it. I put a thermostat gasket in for right now.....so i can get home. I performed a boost test after the tstat gasket was installed...it holds boost. I dont want to get flamed...i will but the metal gasket in asap.

i was running no intake at all and did not hear this high pitched whine until i bought a cheap filter from pep boys and threw it on... now i hear the whine every time i hit WOT... could it be the intake i put on? i will check the ic pipes tomorrow for leaks and post back

Maybe see if your oil return line is crushed/crimped

I had a 1.8t gti that did the same thing years ago. Never effected performance so i never bothered to look into it.
