Oil Return for Anti-Splat Separator

Just bought the ASA Air-Oil Separator, as I think I'm loosing too much oil from the breather.

Trying to find a spot for the AN4 return line :confused:

I don't have the plugged port recommended in the instructions on my O320-E2D. The only other port I see plugged is pressurized by the line from the oil cooler.

Any recommendations? Worst case I have a 1/4 aluminum plate covering my vacuum pad I can tap into as a return, but this is a higher than what is recommended in the instructions.

Or, do not return to the engine. I collect the drain from the air/oil separator in a pint can. I figure the oil that plates out from breather venting may not be the best to add back to the engine.

At each oil change the can may have 3/4” or so in it. Not much, but more than enough to make a mess on the belly.
