What's the best way to rig up the crack case ventilation/breathe hose? Most just put a little filter on the end of the pipe. It this the best way ? I'm sure I'm getting gasses coming into my car. ATM I've just have the breather free coming into the engine bay. Is there a best way to redirect it i. E into the exhaust or sir intake? I'm running a v6 Bob.

Catch tank is the obvious answer, I'm surprised you can get it through IVA/MOT just venting it to the road.

OEM crankcase ventilation takes it right back into the intake on my cars?
