Diesel catch can or vent it to the atmosphere?
I have turbo diesel Toyoya Hilux 2020 (Not sold in the US), and I'm thinking about installing an oil catch can, the thing is where I live there are no environmental laws about these fumes.
In terms of performance should I get a catch can or make the PCV valve vent it to straight to the atmosphere?
PCV systems often have a a breather and a valve which can suck. This helps scavenge moisture, blowby, and other gases out.
