I have thought about the problem of keeping the pickup covered during climb and descent.
How much of a climb angle would be tolerated before a problem develops. Riding down to Sun&Fun in the Bonanza I decided the angles involved were just too shallow to be a factor. 
 
Maybe that's because you were in a Bonanza :-)  
 
In previous versions, I had a problem with the oil level being too high in the front cover area.  This time around, I extended the pickup tube a half inch, and shortened the dipstick tube a half inch, both to make up for the sandwich mount plate.   This half inch of oil level reduction hasn't probably helped as much as I'd like.  
 
I'm almost certain that the main annoying oil leak I've had is oil that's being thrown at the CAS, and leaking past the stock o-ring.  McMaster Carr has metric o-rings that are .5mm thicker, so I just put one of those in for a tighter fit.  While the CAS was out, I looked in the hole, and found that the oil sits pretty darn high in 3 point stance on the ground, and this isn't nearly what I can achieve in climb.  
 
The last couple flights have been with the oil on the full mark, and I've started to get some oil collected in the vent catch line.   In other words, if I do this again, I'd make a conscious effort to lower the oil level even further.
