2.6. Oil feedback to crankcase

Oil separated by the recirculation filter shall be fed back through a hose to the crankcase and always above the
crankcase oil level.

2.7. Blow-by gas feed pipe to the air intake

Connected downstream of the crankcase pressure control valve, this pipe transports the filtered gas to the engine
air intake.
On gas engines, the blow-by gas feed pipe is connected between the air filters and the compressor
(Fig. 1, 2, 3 and 4)

2.8 Crankcase pressure

Monitoring the crankcase pressure will enable you to detect and follow-up the evolution of possible failures due to
a malfunction of the recirculation system or the engine.
The crankcase pressure can be measured at the connecting rod cover or oil sump filling plug or crankcase
breather cover, using a water gauge.
