Moment of truth, or point of no return for these housings...
The original "oil-nozzle" must be removed before milling or else my tool, or my housing will be broken.
Started with a M10-bolt and drilled a Ø4.2mm hole to allign the drill.
Threaded M5, and pulled it out with some washers and a M5-bolt.
Machined a Ø63mm hole for the thread, and then removed all stuff the pointed out form the housing.
All done. Next step is the inserts!
