Dale, The M-20's may be contributing to your moisture problem. Tom Carr, Mike Busch and others have written commentaries concerning their use and have been quite negative in their opinions of same. You might want to research that topic and reconsider if the convenience is actually worth their use. I have found keeping the oil sumps between the 7-8 quart level provides more than adaquate oil cooling while keeping the oiled belly syndrome within manageable limits without any seperators dumping back into the crankcases. If you're still blowing significant quantities of oil overboard at the seven quart level you might want to investigate the possibility of the seperators merely masking some other problem.
