Is it a headstock type lathe where the gears are immersed in an oil bath with a bolt-on top cover? Or more like the link you posted #4 which is a different open-the-lid type which exposes sets of sheaves to change speeds type model? If the former I've been told the top lid gasket will often rip especially if its old. Maybe someone can chime in about making gaskets but I've seen links where guys have had to deal with RTV-like gasket sealant & it can be a real bugger to remove again.
In terms of leaks or the oil level sight glass there are likely other 'seals' associated with shafts that lie beneath the oil line. You would have to refill & see where oil was leaking. Sorry, I don't know what the seals look like. They could be unique to the machine or more standard rectangular ring profile or... If you cant find an exact manual, you might be ale to interpolate from other generic lathes.

Some of us are also on this website which has a sub-forum called Asian Lathes & Mills. Maybe someone will recognize if you post pics or more details.

im away working so not able to take pics but im sure just the bearings are wet when i get home again i will post some pics but that might not be till xmass lol
 
My lathe has several bad seals. Result of a bad mover 25 years ago... Still runs fine, but I promise to fix the seals one day! The point is, you can use the lathe by keeping the bearings oiled;

In many lathes (like mine) you have to destroy the bearings to get them out which is the only way to fix the inner seals.
 
by the amount of oil I cleaned up it has been leaking for a bit but all is still tight maybe just use some STP or some thing that will stick to the bearing better ??
 
I'm no expert but my experience is that for the past , say 22 years, light gear oil has kept my bearings wet and tight. I'm looking at replacing the seals (again), but I still am having confidence issues with every millwright I encounter. [none seem to have the requisite experience]

- so no I wouldn't recommend STP, but it is very possible it is a better solution than mine.
