Positive Crankcase Ventilation: Service and Repair

Fig. 145 OIL-TRAP DRAIN HOSE:

Drain hose:
If the drain hose is incorrectly installed or if it is too short (outlet must be below oil level), it's possible that the crankcase ventilation will not function. The hose may also hit the crankshaft and could get damaged. Fig. 145.

Fig. 146 OIL-TRAP DRAIN HOSE:

Oil Trap:
When removing the oil trap, make sure that the drain hose does not come up as well. If drain hose needs to be replaced or serviced, the oil pan must be removed to make sure that the hose is in the correct position when installed. Fig. 146.
