How much boost are you running now? Do you get crazy high EGT’s with this setup?

Hi I was just confused by this. I thought it was better to do away with breather pipe going into inlet pipe to avoid the smokey hot air. I'm just wondering how to have my catch can, at the moment I have my rocker cover breather pipe going into a catch can that drips into sump. I have 2 openings ontop of the catch can, the second opening used to be plumed into inlet pipe and overboost valve. Now it just hangs open spewing smoke into engine bay. I have quite abit of blow by on my 4jb1 but goes away upon reving.

Cheers
