"Respirator" of the engine

Dear friends:

I recently found some drops of oil in my garage's floor, that come from my 147 1.9 JTD 16V. I've checked the case with a cousin (which is a mechanic) and we saw that the "leak" comes from a black plastic tube which is locate behind the engine in a vertical position. In portuguese we call it "respirador", or "respirator" in english and every car has it. Is something like the pipe that allows the engine to "breathe". For example when the engine as too much oil, the excess of that oil get ou of the engine through this tube. Usually is it just a humidity, but as time goes by, the humidity becames oil and starts to drain to the floor.

I wonder if someone knows how to avoid this situation. I refer that someone told me that Alfa just give order to clean the zone anytime it is made the service, but we don't believe it!

Re: "Respirator" of the engine

Well, i've done a research on the eLearn and i found that the problem is on the cranck vapour\gas recirculation system. Can anyone tell me what to do with the situation? Is enough to take off and clean the oil separator?

Thanks for the support!

Re: "Respirator" of the engine

Usually the engine breather pipe has what is called a collector. The excess oil drains into the collector which you then clean out when full. Although this is only the case on much older engines. I would imagine the newer engines have some sort of system whereby excess oil is fed back into the sump. Gases from the engine crankcase will be fed into the intake as they are deemed poisonous.

I would suggest dismantling and cleaning out the system if you have the inclination.
