Service Procedure: Notes
To insure proper operation of "open" crankcase ventilation system it should be serviced once a year or every 12, 000 miles. Disconnect both ends of hose and freed of obstructions replace with new hose. Remove crankcase ventilation valve assembly from rubber grommet. If engine is equipped with crimped type valve no further disassembly is possible and a new valve should be installed. Clean crankcase and intake manifold connectors using care not to allow dirt to enter openings. Remove crankcase oil filler cap. Clean cap in solvent, blow dry, and re-oil.
