I recently had some avionics upgrades done that eliminated my need for the vaccum system on my Travel Air. The vaccum pumps were left in place and will be removed at next annual when the cowling is off.
On the the Lycoming O-360-A1A, will this remove the air/oil seperator as well?
Any thoughts on the effectiveness of the original Garwin seperators? They tend to be in the way during oil changes and I am always in favor of simplifying where possible if they are left in place after vaccum pump removal.
