Rb26 Rb20 Cam Covers, Internal Vent / Breather Things ?

[gillies2001]

Does anyone know, what are the 2 little brown plastic, vent / breather things INSIDE each cam cover on the RB26 engine.?

The RB20 has 2 metal, vent / breathers things IN each cam cover.

As all RB cam cover breather chambers are vented (open at one end) into the cam covers, i dont understand what the purpose is for the 2 vent /

breathers things

They stop oil mist.

Thanks GTSBoy

So, Does the crank case pressure, including some oil (the oil mist) enter the open end of the breather chamber, and then does the oil finds its way back through the vent to below the breather chamber.

Have i got system sorted now ??

Cheers
