Update on this - I have done approx 2500 miles since install, mostly short local trips. I take care not to give it too much gas at least until the engine is fairly warm.
Engine is running fine, not had any error codes popping up since the rebuild / cam chain / inlet port clean job.
I emptied both catch cans today, they each had approx 1cm of gungy brown emulsified oil / water in them.
So from that (unscientific) test, I would say if you only run one can then you are probably only stopping 50% of the crud that you could be stopping.

Hi! Reading this I am well impressed with the thorough work you've done! I have a quick query, as someone looking to do the same dual can install, how did you solve the issue of attaching pipework to the fittings on the inlet manifold and rear left of the rocker cover? I have seen people butcher old OEM breather pipes for fittings, but am curious as to how you have done it here as it looks very clean and neat!Update on this - I have done approx 2500 miles since install, mostly short local trips.

Thanks Dave for getting back to me so soon! That all sounds promising. I have some 19mm ID EPDM oil line hose which I had planned to use so that sounds perfect. Unfortunately the catch cans I bought a while back don't have any 19mm fittings so I have had to include a reducer and some smaller piping in the system, but should do the trick! Kudos to yourself for thinking a step ahead!OK, thanks.
It's been a while since I did it but from memory it's all 19mm ID rubber braided hose, (not PVC, as the bends would kink PVC hose) and it's a pretty tight push fit onto the Mini OEM fittings. I haven't used any hose clips, didn't need to. I also bought catch cans with 19mm hose fittings to make it easier.- like these - Billet Aluminum Oil Catch Can Tank Bottle for BMW N54 Engine 500ml 19mm | eBay
I think the cans normally sold for the mini application have smaller hosetails so would then need adaptors either at one end of the pipework or the other ? - just makes sense to me to keep the pipework all the same diameter and keep it simple.
I also find that the easy way to empty the cans is to unscrew the dipsticks and suck out the contents with a Pela oil extractor, it's a 2 min job that way with no fiddling about and almost no mess.
Dave.
