1.9TD - oil separator?

Hi,

just a silly question - should there be any kind of oil separator (like wire mesh?) in the part marked on the drawing? Mine has none, and quite a lot oil ending ultimately in intake.

Re: 1.9TD - oil separator?

Having the HDI lump, I dont know the engine but if there's no mesh indicated in the in the diagram
it kind of  suggests it's not standard fitment.
Unless of course it's an unmentioned part of a larger assembly.

Ken has the 1.9TD and may be able to shed some light on this.

Looking at the diagram and item no7
Shouldn't that allow venting and control the release of crank case pressure
whilst keeping most of the oil where it belongs?

Do you have higher than expected oil consumption?

Re: 1.9TD - oil separator?

Hi,

my question is, if the mesh is integral part of assembly 1. Part no. 7 has changed with introduction of Euro2. In mine, which is Euro 2, it is a spring loaded membrane that closes on high underpressure in intake. I think it should avoid sucking gases from crankcase by turbocharger. There is no feature for oil separation. I don't know what was it exactly before Euro 2, but the new version is mounted the other direction than shown in this pic.
In my understanding if there is no mesh in in assembly, then there is no other oil separation then by gravity (which doesn't work really well with oil droplets).

Yes, the oil consumption on mine has started to increase reaching recently approx. 0,5l at 1.600km. There is also more oil in intake than before, and I try to understand if it is the turbo (brand new from Mahle installed only 60.000km ago, little wet outside, but still reaching 0,95 bar at trottle fully open) or comes from crankcase.

The only one I'm aware of is more of a "stop you dropping a paper towel down there" filter, I wouldn't describe it as a mesh. There may be something underneath that though, although the dipstick goes through it so I doubt it
