Your car was designed to have the crankcase gases recirculated back into the intake. It is not designed to have an open breather...

i agree with kilgore

if you dont believe us turn the car on and then remove the hose that goes into the plenum.............. the car will die on the spot

so now i have one breather and on the passenger side with the manifold blocked off and on the drivers side i have the hose on the valve cover going into my pipe that goes into my supercharger and its sucking in oil....this is how ive had it since i got my engine back in and it runs like crap...do u think this is the reason or could it be my bypass is to small after i upgraded to a d1 procharger thanx rob

With only one breather, you are letting unmetered air into the system, and potentially causing a lean condition. It is better to have the entire system working, and if oil is a problem get a pcv valve for a supercoupe. If that doesn't work get a catch can. If you really want to go with breathers, you need them on both sides, but this elimnates some of the backpressure on the rings cause by the pcv system, which help seal them.

I would do an oil seperator like RJSTAAF discusses in this thread:
