I've got catch cans on one of my cars, but a racer told me I should go back to PCV to get the vacuum on the inside of the motor and avoid the pressure buildup that will cause gaskets to leak, etc. I told him I didn't want to be burning oil back through the intake but he said in a street-driven car the horsepower loss is very minimal.

My catch cans were installed by Lingenfelter and have the brillo pads vents. Are the catch cans you guys are using sealed? Probably not if they have a dipstick. But why not get a baffled and sealed catch can and put the catch can downstream of the PCV valves and get the best of both worlds?
