"rocket-list" , "rv10-list" --> Rocket-List message posted by: "JOHN STARN" The Lyc IO-540 J4A5 in HRII N561FS has the internal oil system that sprays oil on the bottom sides of the pistons. This "spray" would increase air borne oil droplets who could then find their way out the vent system. Have been told that this spray system is used on Turbo'ed optioned Lyc. etc. to increase cooling on the higher HP engines. The J4A5 in 561FS is only rated at 250 HP. Not sure IF or what 320/360's use this system but I would assume this type of system would also be on certain 4 cylinder Lyco. too. I do know anything over about 9 1/2 qts. in 561FS gets pumped overboard. Check the archives IF your interested IMNSHO in what I've posted on oil separators. (not favorable).
