My car is highly modified with a supercharger, complete exhaust and more. I've been advised to isolate my intake from the PCV system to prevent oil mist from flowing into my Supercharger and intercooler. To do this I've been told to run 2 catch cans vented to atmosphere. The first one from the Valve Cover and the second from the PCV valve on the crank case. My concern is that running vented to the atmosphere will create no vacuum in the system as it does in stock form. Is this problematic or will the engine run safely like this? One specialist in Miata's advises me to do this, and another claims it will cause problems with the bottom end and piston rings not seating correctly. I've scoured Miata forums and done google searches and keep finding conflicting information.

I use straight from the PCV valve a vacuum line ran to a air compressor in-line canister made for air compressors and air line systems like you use in a garage that catches all the excess water or oil from the compressor lines to keep it out of air tools like nail guns routed back to its normal place on the motor and it catches the oil and I drain it when it has some in it from the valve in bottom and it is clear so I can see anything in it, I just checked it today. I also added a piece of vacuum line to the tube below the release valve that goes below the engine and its mounted to inside fender well.
