Contour Enthusiasts Group Archives Forums Modifications Zetec Maintenance Crankcase Emissions Air Filter

According to Ford's maintenance site, I'm supposed to be replacing this thing, but I have no idea what it is, what it does, or where I can find it to replace it. I tried looking in Chiltons but it isn't even mentioned there. Is this thing even important enough to bother with?

TIA

I think it may be the little block of foam located in your main air filter housing.

Open your air filter housing and take out the air filter. In the back corner of the housing is a little retangular box. (A hose clamps onto it from the outside.) There are two tabs holding the cover on the little box. Take the cover off, and there is a little block of foam in there.


Purolator refers to it as either a Crankcase Ventilation Filter or Breather Element.

Purolator Part Number B15064

My Haynes manual refers to it as a "Positive Crankcase Ventilation (PVC) system filter".

You may be able to clean yours. Mine was too far gone so I replaced it. Cost me $2.00 for a little chunk of foam. If I can find some packing foam with the same density that's what I might use next time.

I hope that is what you need to know.

Take care.
