Default N/A catch cans, why do some have breathers?

i thought the breathers are just for FI? how come i see some vented catch cans on NA setups?

Wouldnt this create a crazy vaccumm leak? unless there is a check valve installed between the can and the filter


also, would connecting the valve cover vent (the one that connects to the intake arm) To the catch can, and having all that route back into the IM, have any benifits? I would just plug the hole up on the intake arm.

Also have the catch can line, that runs into the IM, branch with the cruise control vaccumm line, to help pull additional air in, yay? or nay? just want the most efficient setup, and i dont have cruise control, that is blocked off....no emmissions here either

This allows it to vent into the atmosphere, so no more oily residue gets sucked back into the T-body/IM. The vac. leak only occurs if you have an open vac. source which is probably the IM in this case.

This setup is good if you are running on the street where emissions are a concern. It would allow oily air to be filtered a second time after the OEM oil separator box (blackbox) on the back of the block.

Maybe you hooked it up wrong?

Follow these instructions and you should be fine. I did this with a modified Greddy can and its good.
