I buttoned back up the magneto blast tube that I had previous clamped to the old breather tube. Since that was removed when I installed the oil separator, I had to find a new place to clamp it. The return line from the oil cooler was right next to the old breather tube, so I clamped it there which worked out great.
After that, I spent a solid hour inspecting the entire firewall forward area to make sure it’s done. Other than the cowl finish work, I think the firewall forward is complete. I’ll have a builder inspection party before the DAR takes a look at it, but I don’t think I have anything to do in this area before then.
