OCS?
I think that means "oil canister separator"? ...but I'm not sure.
Or maybe OSC: Oil separator canister?
CSC calls it the oil/air separator.
Here's the explanation of what the OCS does according to Joe B. on the CSC Blog.

On all my current/previous motorcycles the crankcase vent tube runs directly to the air box.
So at 5,081 miles on my RX3, I changed the oil (20w50 Mobil 1), and replaced the oil/air separator with a hose directly to the air box.
One thousand ten miles later:
Another oil change:
The good part:
The magnetic drain plug was not full of sludge as on previous oil changes.
Only small particles:
The part that has me concerned:
The oil level sight glass (it was at the mid point at the beginning of the experiment):
And the air box drain tube:
Previously, since new, this tube has been empty.
Tomorrow the oil sample goes off to Blackstone.
On a lighter note, the RX3 has been running GREAT!
No stalling, smooth transmission shifting, good stopping brakes, good power and handling on the steep, curvy mountain roads.
Yesterday at Lake Nottley, near Blairsville, North Georgia:
