Just did this experiment at work, during smoko of course...

So with pure vacuum there is no liquid movement between the vessels (vessel on left is the catch can) Catch can collapses under vacuum. With a partial break in vacuum at the vessel on the right(sump) the catch can easily sucks the water up from the sump.

So catch can with vacuum and draining back to sump is a no no. If it had a breather to atmosphere (dazdavies, Gordon) it will work but then there would be no point running the pcv to it then would there...

I wouldn't want to rely on a nrv to prevent oil sucking back up through the sump, I work with them everyday they fail and pass regularly.
