Every 192,000 km [120,000 mi], 3,000 hours, or 2 years, whichever comes first, clean and check the crankcase breather tube.

The tube must be removed and checked internally for obstructions or sludge buildup. If the tube is blocked, the tube and crankcase breather must be cleaned or replaced to prevent excess crankcase pressure buildup.
