Description
1. Crankcase ventilation system is available on all models, but systems may vary depending on the model.
2. Oil vapors and gases that have broken through from the combustion chamber (combustion products that have passed through the piston rings), are sucked out of the crankcase through a hose into the cylinder head area above the camshaft. From there, the gases enter the intake manifold/throttle body (depending on the model) and/or heater block on the carburetor (if any), where they are re-burned with the fuel-air mixture, resulting in a reduction in the amount of harmful emissions into the atmosphere.

3. Some models have a filter inside the camshaft cover, which, if clogged, must be cleaned with kerosene (see illustration).
4. On high mileage vehicles, especially when the vehicle has been used regularly for short trips, a gelatinous substance will accumulate inside the PCV hoses. If there is excessive carbon buildup, the hose in question will need to be removed and cleaned.

5. Check the system hoses periodically for tightness and replace them as needed. Please note that damaged or loose hoses can cause various engine problems that are difficult to trace.
6. The crankcase breather/dipstick tube can be unscrewed from the cylinder block after disconnecting the hoses. Use a new gasket when installing.
