I've heard people say this a few times, but I've never understood this logic. The pcv works very well until it's flooded with oil, and then it's overwhelmed and passes the gunk to the intake. Why would you remove something that functions perfectly fine 99% of the time? The inline catch cans just collect whatever gunk the pcv would have passed on. By removing the pcv, you're removing a closed loop system, and how does it even affect crank case pressure? Those aftermarket plates most likely don't seal perfectly...and none of them have even close to the amount of baffling that's necessary.
Both types of cans will function to prevent gunk in the intake, but neither actually fixes the problem... They're just bandaids. I'd still take a can over none, but I'd rather have the inline... And ideally the baffled pan is where I'd toss my money...
You don't want the gunk coating the back of the valves.
