Hello Forum,

nice to be here. I have a 4age I have turbocharged sitting in a ae86. I've bunged up the plenum ( from where the original breather pipe went from the cam cover to the inlet plenum )

Now I have the cam cover pushing out a lot of air. Like a vacuum on backwards.. What can I do with this breather pipe? Its not blowing out oil or anything but it makes the car cabin smell of fumes.

I've consider a catch can with a small filter on it and another exit going back into the pod filter

Any help, pictures, advice is wholesomely appreciated.
