Don't know Yanmars, but a lot of crankcase vents have ways of stripping out the oil while letting the air pass thru. Sometimes with baffles or with some kind of media. Often it looks like steel wool. As time passes, dirt builds on the wool, restricting the opening and causes the air flow to be more forceful. Cleaning or replacing the media sometimes solves the oil dripping problem.
