a housing having a gas inlet and a gas outlet; and
a stack of separate elements of porous material for coalescing oil mist passing therethrough arranged in the housing in series in the flow path between the gas inlet and the gas outlet.

2. A crankcase breather according to claim 1, wherein the elements of porous material are planar.

3. A crankcase breather according to claim 1 or 2, wherein elements of porous material are circular discs or annuluses.

4. A crankcase breather according to any one of the preceding claims, wherein the porous material is synthetic material.

5. A crankcase breather according to any one of the preceding claims, wherein the housing has a baffle arranged to extend the length of the flow path between the gas inlet and the gas outlet.

6. A crankcase breather according to any one of the preceding claims, wherein the housing mounts a cyclone fin in the flow path between the gas inlet and the gas outlet.

7. A crankcase breather according to claim 6, wherein the housing includes a cylindrical internal wall defining an inner cavity in which the elements of porous material are housed, the cyclone fin being mounted around the internal wall.

8. A method of tuning a crankcase breather according to any one of the preceding claims comprising selecting either or both of the number and the type of the porous elements to provide a desired operational performance for the crankcase breather.
