1. Are the metal oil tubes that apparently were installed originally in pre 1994 119 engines still available from Mercedes?
2. If available, can the metal oil tubes be used as a replacement for the plastic oil tubes used in later 119 engines?
It sounds like the metal tubes are superior if they can be used.

To second mbshop, I checked w/ my tech's part supplier and they are not available. I'm not a 'fan' of the plastic version, but as you have found, they do last about 100K miles. So if you replace them, you shouldn't have a problem for a long time.
On my page, there's a pictorial of how to do it; MENU#19. Also mbshop's idea of securing the ends should just about make them last forever.
I've not done this but a good technique would be to use an hot small tip soldering iron. Then position the tip so that it lays across the body and cap; then touch both simultaneously so that the body and cap start to melt and doing so, weld together. Do this every 120 degs and that should secure the cap nicely.
Good idea but may be overkill.
