Yes but everyone agrees that it needs some kind of vent or the crank case will pressurize under boost. Bye bye rings.
From the pic Abdo posted, it looks like he is running one valve cover to each of the Greddy catch can barbed fittings. With this setup, there is no venting. I'm surprised this thing doesn't blow major blue smoke when you drive it. At idle it should be fine since the stock PCV valve is in place and probably connected into the IM.
If you put a vent on the vertical fitting on the exhaust valve cover, the catch can will do nothing because the air will most likely go through the breather filter and not the can.
The breather filter should go on the catch. Then, the valve covers get connected and one line runs to the remaining barbed fitting on the can from the vertical fitting on the exhaust valve cover. If you want to recirc it back into the intake tract and get vacuum on the crank case, remove the breather filter and run a line from there to the intake. Simple as that.
