The PCV is the source of the oil that gets into the intake

Its all up to you. If you want to keep that nasty oil from building up in the intake then you need to get rid of the PCV. If you would like to see for yourself take the throttle body off and stick your hand in the intake. If you take out the PCV and plug the holes a breather is required to vent the crank case pressure. Instead of venting it into the intake you would be venting it to the atmosphere.

You will need to cap the line that sticks out of the throttle body. That hose goes to the front line on the passenger side valve cover which will need to be capped also. There is a line that runs from the back of the driver side valve cover behind the intake to the rear line of the passenger side valve cover. It has been a while and my whole vacuum system has been modified but I think there may be a line that connects to it that will need to be capped off also. You can remove that hose and plug both valve covers if you want. If you do all of that you need to make sure you put a breather somewhere, like the oil cap, to relieve the crank case pressure. I have seen where guys will get a second passenger side valve cover and put it on the driver side with a breather there also.
If you do all of that you will have removed the entire PCV system.

The best way is to run BOTH but with the dirty side (PCV) ran with a catch can. The PCV system helps with crank case pressure IMO better than running with just an open breather because it "sucks" crank case pressure out through the PCV's closed system. Remember, there's little to no vacuum at WOT; therefore, the only system working to force pressure out of the crank case at idle and part throttle is the PCV system. Both ran together has worked great for me.
