  The drain plugs on the oil pan on the O-360 in my Pitts S-1 have hoses 
attached as part of the Christen inverted oil system. There is no other 
convenient drain plug for draining the oil out of the engine.

What is the common method for draining the engine oil on an installation that 
has the inverted oil system?

I noticed that the bottom of the Christen 802 oil valve is about level with 
the bottom of the oil pan. Should I remove the bottom allen screw (the lowest 
of the 3 big allen screws) on this valve to drain the oil? This seems like 
the most convenient fitting to remove but I'm wondering if there are gaskets, 
O-rings, ball-check valve components, springs, etc that will come flying out 
of the valve if I should do so.

Thanks!

P.S. Thanks to the folks who answered my last two questions on the brake 
fluid and batteries.
