...... Can anyone suggest a cheap but effective catch tank then? I heard there is plenty of dodgy ones kicking about that are just 'engine bay bling'.

Perry- I like the concept of drilling the sides of the rockers. So.... I drill/tap/glue some 1/2" hose tails into the side of the rockers. Then run them up to a 1/2" t-piece fitted as close as possible to filter. Cheap, sounds effective, and less buggering-about trying to make space for a catch-tank!
Only questions are:
1) One of the REME Artificers (geeks) at work warned me against this solution He said that the rocker cover could easily crack (as it's cast aluminium) and that those outlet needs to be in the top as that's where the maximum pressure is...... Sounds like rubbish to me. Plenty of engines have their breathers in the side, pressure is relatively uniform and surely the suction provided by the air filter makes it irrelevant?
YOU WILL NOT SEE ANY MEASUREABLE SUCTION FROM THE CONNECTION INTO THE 14" AIR FILTER MATE. IT MAY BE POSSIBLE TO MEASURE A SLIGHT POSITIVE PRESSURE IN THE PIPE FROM ROCKER COVER TO AIR FILTER BUT THIS WILL POSSIBLY BE ONLY A 100 PASCALS? DEPENDS ON THE ATATE OF THE ENGINE REALLY.
THE PRESSURE IF ANY, IN THE ROCKER COVER IS UNIFORM MATE. ROVER ROCKER COVERS CAN BE DRILLED WITHOUT THEM BREAKING UP. THERE MAY WELL BE A POINT IN THE ROCKER COVERS WHERE OIL IS MORE LIKELY TO BE FLICKED UP AND EXIT A VENT PIPE. BUT THIS WILL NOT BE ON THE SIDE OF THE ROCKER COVER
2) Is it also worth fitting small air filters to the original outlet holes on the rocker? They are pretty inexpensive, will look better than just plugs and surely the more breathing the better?
IF YOU HAVE ROOM TO FIT SMALL BREATHERS ON THE EXISTING PIPES THEN DO IT AND SEE HOW THEY WORK ?
3) Surely, for almost nil-cost, it wouldn’t hurt to stick an inline T-piece with a 8mm convertor to also feed the small breather into the hopefully newly upsloping 1/2” pipe?
GO FOR IT!
Thanks for all your support guys; super-useful.
