It might be a ring, or it might be valve seals. In either case, look for a pool or puddle in the air cleaner housing below the square filter at the exit of the breather tube.

If there is a pool, then keeping the oil out of the air cleaner housing should be the first step. Checking compression and leak down will rule out seals and rings.
