The top pic is the driver side, and the vent is from the 70s. The original elbow was causing oil to weep at the grommet, and the new vent solved that.

The hose goes to the air intake tube, and thats where I cut in the 2nd valve.

Bottom pic is the PS to show how that 2nd valve is setup. I'm still tinkering with it though cause I think 1 valve should work.
