[decoder22]

i was just curious on everyones opinions i just swapped a D15 Vtec in my 91 Civic The port on the valve cover i put a breather on it i was wondering should i recirc it back into my intake or just leave the breather on :bong:

i would leave it on. just make sure you plug any ports on your intake then.

Unless you want "blow by" oil to come back into your intake, put it on... Or put a breather on it or run a line to the bottom of the car. I hate hot air and oil recirculating back into my car...
