Part 5 – Oil Pan & Oil Level. Build Notes

After installing the fittings for the external oil pump pickup and the B1 head drain lines, I capped the connections and did a water leak test. While doing this, I measured the water added to see where the oil level would be with 7 and 8 qts. The MIL-31150 pan has a built in windage tray that mounts to the metal bridges at the front/center/rear of the oil pan. With 7 qts the level was below these bridges. With 8 qts it was slightly above these bridges; less than 1/8" front. The built-in windage tray slants toward the rear, similar (but less) to the bottom of the pan (4” sump front, 5” sump rear).
