Just wondering what everyone's experience is with regard to oil leaks post fitment of a catch can?

In a previous post I asked how easy it is to DIY a replacement rocker cover gasket and injector sleeves on a ZD30DDTi due to some oil leaks. Just wondering what effect fitting a catch can will have in reducing the probability of said leaks occurring again.

I would have thought by having the intake vac pressure reintroduced to the crankcase via the can that oil leaks would be less likely to happen.

Anyone had experience with this conundrum?

Currently the PCV pipe is just vented to the ground on the vehicle and it's making a mess everywhere.

The intention when I bought the vehicle was always to fit a can but space is and issue that I think I have rectified.
