Dave,
Is that the same for the RHD BN1. I have terrible problems with oil syphoning up into my techometer and dripping on my legs. I have all the seals/metal rings in place at the 'engine' end but to no avail. However my cable goes out through a hole in the bulkhead almost straight to the engine. If I redirected it as per your diagram the cable would effectively form a 'U' bend down and up which might help the problem I have (I would probably need a longer cable than the one I have as well).

hi Steve,
I don't know about the cable routing on RHD.
I do know about the oil leaking into the tachometer.
On the Hundred Fours, there is an oil seal on the tach drive housing. You can see it here, item #95, Oil Seal, Pinion, Moss #520-440. You can remove the drive pinion assembly by just unscrewing it from the housing. Best to work from underneath the car.
There is a retaining ring, item #96, which must be removed to get the seal out. This ring is just a tight friction, fit but can be a chore to remove. Very careful prying with a sharp point such as an ice pick will gradually work the retainer out. I would also get a new gasket, item 94.

When my cable started dripping, it had put enough oil into the tach head to seriously screw up the tach movement. I carefully took the tach apart & flushed the moving parts with brake cleaner. Reassembled everything, & it works as good as new plus no drip.
