Fig. Fig. 1 The crankcase ventilation filter is located inside the air cleaner housing

This filter, located within the air cleaner housing, should be replaced at least every 24,000 miles or 24 months on cars built up to 1974, every 30,000 miles or 24 months for 1975-77 cars, or every 12 months or 15,000 miles on 1978 and later cars. If the vehicle is driven under dusty conditions, replace the crankcase ventilation filter more often. Simply pry the old filter from its housing and install a new filter.
