Do you think that it might help to open the oil

airplane if you know you will be restarting soon?
I'm thinking that you might get a little cooling
air flow up through the door. Would it be
significant cooling? I don't know. Just an
idea.
I just wanted to confirm that the idea Mike suggested here works very well in certain installations which I know of first hand. I flew a Cessna 310 (twin TSIO-520's) for several years in the Southwest (warm) and found that opening both oil doors immediately after shutdown (and then closing them before startup, of course) provided quick and painless restarts of both engines after as little as a 10-minute shutdown. Also know a guy who built a Glasair-3 with the oil door freely floating on it's hinge (rather than having a latch). He added just the right counterweighting to the door so that it would close from cowl pressure above about 35 KIAS, but would flop open automatically below that, providing the necessary cooling to easily restart the FI Lycoming (the Bendix RSA system is easier to hot-restart than the Continental anyhow). Maybe that would be a viable approach for a Lancair?
