Boosted crankcase oops

So i think i put boost to my crankcase its lq4 block heads and valve covers with ls1 style intake and throttle body, passenger side vacum on the throttle body hooked straight to the valve cover and driverside valvecover vented to open air. Does anyone know what gets ruined when this happens any input is appeciated thankx.

At first it was running good but was getting no boost then i swaped my tiny intercooler with staight pipe then it was running about 3 lbs with 12lb spring in the waste gate but as soon as i made coulple good pulls made some noise ,knocked and smoked and now it dont smoke or knock but seems to misfire and little tick? it took me a day thinkin then realized my vacum was routed staight to the valvecover.
