N52 PCV Delete

I know this might sound more trouble than it's worth

N52 ccv seems to be a lot more trouble than it's worth. Has anyone attempted a diy ccv delete? Theoretically it shouldn't be hard but I'm curious.

Could prevent some major headaches I feel.

Thoughts?

I have deleted it when I went n54 I take manifold with catch can but I get rich mixture faults. I’m looking into finding the correct size pcv valve to run in line of the catch can.

I have the plastic vc and stock manifold. Does the car really care if I'm using a catch can as long as I plug the holes on the manifold?

Having a plastic valve cover I would leave the ccv until it fails and then just replace it since you can get them for $40 and not have to do the whole valve cover assembly. As far as the catch can goes, I ran mine from the pcv heater under the intake manifold to one side of the can and from the back of the valve cover to the other side of the can. I used the Stock hose clip connectors and hose clamped them to silicone hoses. I think I have pictures here somewhere.
