I've removed the plastic UL Power Air oil Separator and installed this simpler Super Slime Fighter. This comes with great reviews and the ability to completely remove the smaller drain back line to the sump. Now, I'm not trying to mask my blow-by issue at all, but simplifying the setup is always a plus. I've even been able to install it using an adel clamp on the orginal mounting bolts. Cooool. Now I'm just needing to pick up a 90 degree brass fitting and I can finish this bad boy up. Almost ready to fly!
