Will test my evacuation system on the weekend. The tubes will go into one breather on each valve cover. The other two breathers are closed. This will cause vacuum and I hope to get the leaks stopping. New dizzy seal nad o-ring again, new oil sump gasket too and new oil.

Okay gents,
After try&error I think the problem with the dizzy oil leak is solved. Thought that the little but permanent oil puddle under the dizzy stump came from the the bolt hole from the clamp or the O-ring because of too much pressure. Disconnected my additional oil feed pipe for the dizzy, still leaking. Changed the bolt to a stud and renewed the O-ring twice, still leaking. Was sure that the evacuation system (tubes from the breathers to the exhausts to produce vacuum) would be the BIG help to minimize pressure, still leaking. Renewed the dizzy O-ring again, a bit thicker and just fitting in, still leaking. Removed the dizzy again (I don't know how many times) and recognized oil under the cap!!
After removing the black plastic cover inside the dizzy and after additional inspection I could see a 2 mm high oil puddle at the bottom of the dizzy body!
The body has two small holes at the bottom. The Rover dizzy sits at an angle as anybody knows. Not vertical as a Ford or Chevy. One of the hole is at the lower position of the dizzy body when mounted. The addional oil feed for the dizzy is great to minimze the gear wear. But the aditional oil on the gears will cause oil inside the dizzy along the spindle too and that is turning to the top aka the body. When the oil is on a certain level in the casting it will drop through the bottom hole of the casting and hit the timing cover at the area where the clamp sits.
I disconnected the feed pipe again and made a 5 miles test drive yesterday. No oil anywhere
I hope that this problem is solved but that will show a longer run.

Well,
After a 30 miles drive, new oil puddle
It drives me crazy but I'll find a solution.

Re: BRA289 customized recreation
After mounting the second time a brand new dizzy, the problem is solved
The 360 miles trip to SPA proofed that. The other "old" dizzy, that was laying on the shelf for a few years had a inside a weak iseal that allowed the oil to go up the spindle to the dizzy body and drops out of one of the holes directly on top of the dizzy clamp.

Re: BRA289 customized recreation
Thought it would be a good idea to cover the headlights and the indicator inside the wings to avoid dirt and water to the electrics.
Mounted rivet nuts to 3 brackets and "glued" them with Sikaflex to the GRP. Another 2 rivet nuts to my bumper bracket. Carboard template and then aluminium covered with a rubber edge seal. At the bottom 15 mm space to let the wind and water from the front getting out.
