The oil door bows out and is clearly allowing significant cooling air to escape.
I couldn't figure out whether seals like those shown would reduce the bowing and the cooling loss so I just did it using some sheet silicone bonded with silicone sealant.
It worked. Too bad I had to leave gaps for the door latches because it allows enough air to continue to bow the door slightly.
On the door you can see a previous and extremely lame attempt to stiffen the door with some carbon thread. ha! No effect. A all carbon door would be much better.
