Does the arrow need to face the hose coming from the pcv valve; or does the arrow point to the hose that connects to the intake?
Arrow goes to intake.
So then it's set up correctly then. Reason I asked is because I went for a drive yesterday, and I collected no oil.
Is that a bad thing?
Give it time. I'll double check mine.
My arrow isn't visible unless I take it out.
Did you remove the filter that came with it?
Actually, you don't HAVE to, but the oil droplets form faster if there is something there to form on. In the open atmosphere, droplets form around dust particles. The steel wool or screen material acts like the dust. So it will work better with something in there to help the droplets form.You have to put steel wool inside or those copper scrubbers.
