I knew I'd seen it before. That's my exact solution and it works perfectly.

 
Was going to suggest this :).
 
A nice downhill free flowing path.

It's the most straight forward and simple.

What's on the inside?

 

Not sure about over oiled transfer leaks as it'd get centrifuged away from the primary bush and seal. I'd also think they get sloshed with far more when cornering left. I've not tried it though, so just supposition.

It was discussed as a drain previously on Turbominis and a few people had leaks because of it.

Dont forget thats very hot oil coming from the turbo. At idle, there isnt going to be much centrifugal force to get it away (none at all with the clutch depressed). Anything directed in that area could flow into the little holes instead of out.

By all mean give it a go, Ive not seen it first hand but it made sense. Especially as said people moved the return and had no more leaks.

As said. The crank/big end rod gets very close there so I'd aim to have the drain between the cylinder or you'll have the crank acting as a restriction as it passes by the drain.

Thanks for that, chap! I'll have a look in the upcoming weeks for the exact location. However i'm not too fussed about it being near it as the crank would actually be moving away from the drain on its throw (engine runs clockwise when viewed from the timing chain) and the drain would be under the windage tray.

I was just wondering how the adapter was bolted to the Mini gearbox casing.

Some  stuff to think about there. The heat being the worst. You could direct the flow and if the primary isn't turning neither are the other tranny gears, if they're playing a part in chucking oil at it. You make a good point that it's not straight forward - Steve's criteria in #31.

Bolts from the inside onto locknuts on the outside. However I'd most likely be wire locking it

Strangely that's the way I've ended up going. Bought an AN10 boss for the box and having it welded on this week. My concern was that it would leak with the rover oil return.

There was no chance of me getting mine to fit and work properly draining into the fuel pump hole, good luck with it
