Oil separator install question...

[35Remmy]

OK...got everything hooked up...on the bottom of the separator there is a petcock valve to drain the oil...BUT...I'm getting suction from this valve. If I put my finger underneath the petcock while the truck is running I can feel suction...it's like a little nipple with a tiny hole in the end of it.

I have the PCV valve going to the IN port on the separator and the OUT hose going to the upper intake. Isn't this correct?

You shouldn't have any vacuum leaks on the fittings. It might not be tight enough.

Turn the valve both directions to see which way closes the valve. I've seen those valves go both ways.
