Large drop in air oil separator for long life less maintenance cost  ( not small spin on separators used by others cheaper way short life )

Separate oil sump for the large oil capacity

All air and oil lines are stainless steel and coated lines  (not hose, used by others, cheaper up front, costly to replace. Hose will fail and leak)
