I got hold of a universal catch can from a friend - it's like this one from ebay that goes for around £30 .... http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 0247678060
now where do I mount it?

Can you see what it is yet (spoken in an australian twang)

With the power steering fluid cover removed (there is nothing underneath, so ideal for hiding it away). The cover needs trimming slightly at the back BTW.

Cut the hose going to the bottom of the PCV valve and extend it to one of the inlets on the catch can.

Now add a return line back to the PCV valve.
Job done & looks pretty OEM once it's hidden by the cover.
