Crankcase Ventilation: Maintenance

Every 15, 000 miles or 15 months, clean filter element and inspect all hoses for leaks or deterioration. Replace filter element and PCV valve every 30, 000 miles or 30 months (24, 000 miles on Capri). Perform maintenance more frequently if vehicle is operated in dusty conditions.
