Default Cusco oil catch tank on b20v 13:1

Has anyone used the Cusco oil catch tank on all motor b20vtec? I have the block ports from Honda And the Cusco catch tank kit. I'm wondering if I run both lines to the two block ports or not. The can isn't vented so idk if it should run from block to intake or what. Thank you

I have a built b20v 12-5-1..my tuner said the ports on the block are a bit over kill unless u are F/I..might be better off welding 2 bungs on the VC and running a can with a filter.

Keep the can. No point in doing the valve cover version. It's not going to vent as much as you think, anyway.

The reason I went with the block ports is to not have to tap my valve cover. So should it be fine using both ports to the can or should one go to the intake manifold? Thanks for the responses though for sure.

Both.. But use a one-way check valve (Volvo S80) on the valve cover

Oh ok, so use this check valve? From valve cover to intake tube with check valve in place? What way should the valve be? Pic of my engine also.

Ran mine off the back of the block like this. Then removed the window wash fluid reservoir to mount it. Worked like a champ. I revved mine hard (9500) and it did vent a decent amount.

Black side faces the intake manifold, white side faces three valve cover.

Acts like a BETTER PCV system
