Hi guys,

As a newly found Defender enthusiast I have a bucket load of questions about why Landrovers are designed in the way they are.

My 300 is fitted with an oil cyclone breather, after disassembling the unit I can't help but feel it does absolutely nothing at all.

So I looked online to see what the benefits of a catch can would be, doing a fair bit of research the catch cans seem to... well... catch, and quite well, showing signs of picking up nasty gunk...

What's everyone's opinion of this?
