Haven't looked at your pictures, but you are probably referring to the CAM OILER TUBE, which does just what it's name describes. It squirts out oil onto each of the cam lobes as the engine operates to keep things nice a greasssssy. In most newer cars the cam lobes are oiled internally though actual holes in the lobe and there is no external cam oiler tube like our engines have.

The later turbo heads did have an internally oiling camshaft I would recommend installling one as my old l24 had been broken at one end by some i think (grease monkey) that did it while we were getting her roadworthy.

I noticed when adjusting the valves it was sitting in the corner ready to damage other parts.

I would highly recommend a internally oiling one such as our turbo ones with the P90 have.

Just a suggestion.
