Just installed a Killer B oil pan (and arctangent oil control plate) last night and haven't added oil yet. A light bulb went off in my head the moment I woke up this morning. Wish I thought of this before the installation, but maybe it's not to late... AOS drain directly back to the oil pan.
Is having the AOS drain directly back to the pan a silly idea? I can't think of any reason not to. The AOS came with a fitting to share draining duties with the PCV crank case fitting, but I haven't used that fitting because I haven't had my BAR inspection and I'm sure it would raise a red flag. Currently, I'm draining into a jar. Draining directly to the pan seems better than sharing the PCV crank case fitting.
What if I tap a fitting into the oil pan for the AOS drain? I think the Killer B pan is plenty thick enough to thread in a barb fitting.
I don't have any material to do an experiment and I really don't want to pull the pan back off. If I drill and tap a hole, most of the cuttings will come out the drill side of the hole, but how much will fall into the pan? Since the pan has never had any oil in it, I'm thinking I could vacuum out any cuttings through the drain holes.
Another option is to tap the extra drain plug (Killer B oil pan has 2 drain plugs). Advantage: Can be done on my work bench, not permanent. Disadvantage: For some reason, it doesn't seem as elegant. Maybe I'll tap the plug and live with it for a bit. Has anyone done this...tap the extra drain plug for AOS draining?
Update: Just rummaged through my shoebox of fittings and found a 1/2" NPT plug already tapped with 1/8 NPT hole! Going to buy a lottery ticket today!
