Alright, so I did a boost leak test on my car and here are the results,

I set the motor to 30 degress past TDC.

Hooked up my BLT to the throttle body elbow. And pressurized it to 8 PSI just stock pressure. It drops to 0 in like 2 seconds. When I take off the oil cap it sounds like I open a can of soda. I was told that if I have that much pressure in the crank my PCV coul be bad I replaced that and still the same thing happens. I am at a lose I can not find this damn leak and i am afraid something is seriously wrong with the motor. The car runs great though, so I would assume nothing major is wrong. Any have any ideas?.

Also I tried diagnosing before and got a ton of help here is the thread:

but I must be a noob and I can not figure this out.
 
that pcv valve you bought is junk, If you can take it off and blow through it on both ends, its junk.

If you cant blow through one end, its fine. Then you have some other serious problems. Then id say worn rings, valve seals.
