...What would be your thoughts

about a hinged flap on the firewall end of the plate allow drainback

during normal or low pitch climbout but would close during high

pitch climb to keep oil out of the front cover (Tractor installation)?

 

Kelly;

 

I did something along that line on my 20B. Mine is a pusher installation; but I wanted the deep sump near the firewall to keep the weight nearer the CG.  I have about a 2” hinged flap between the sloping section and the deeper sump to inhibit the oil from running toward the ‘rear’ on steep climb.  Don’t have a photo of the inside, but you can get the idea the old photo attached. Normal full level is about 3/4” below the pan flange giving 8 quarts (designed for pan fed OMP).  The level switch warns when the level gets down to 4 quarts.

 

Now that I’m converting to premix, I’ll probably fill to about 6 qts, and add when the light comes on; which probably shouldn’t happen between changes.
