Where to return separated oil from Provent?
I do have a Provent 200 in the crankcase breather. The separated oil is collected into a u-tube and manually drained periodically. A much better solution would be returning it to the sump/engine directly.

How do you guys handle that, hints appreciated.

it has to either return below the sump oil level, or have a 1 way valve in the return pipe DEFENDER 90 TDCI XS,

I hope everyone is well and your land rovers make you happy

The oil collected by your Provent will come through along with hot (and wet) air.
There will inevitably be some water collected by the Oil Catch Can and likely some microbial growth at the oil/water interface, much better to discard that then reintroduce it to the sump.
Might be worth collecting a decent bit of oil and giving it a chance to separate before you commit to putting it back in.

Throw the collected oil away, that's why as standard the engine disposes of crankcase vapours by burning it off - because it's useless oil.

Slightly off subject.

The mention of crank case breathers and microbes takes me back to my ownership of an Austin Maxi, yes I know many will not have heard of them and I'm old, The breather was a length of rubber hose which often approx. every three months would block up with oil and bits of rubber and case running problems. Dealerships in those days would always have plenty on the shelves as they would tell the owners of effected vehicles that it had to be replaced . Most Mechanics, not vehicle fitters, would know the simple less expensive way to avoid the constant replacement, obtain a short length of soft 3/8" 9.5mm ID copper pipe and inset into rubber hose and bend to shape. It was amazing how better the engine breath. Mind this was a trick we used to use on Artic Unit engines back in the late 1960's. Don't make old people mad.
We don't like being old in the first place,
so it doesn't take much to Censored us off.
