I had the same thought about the old Logan here.
Then I got intelligent, and just put flip-top oilers on. It didn't originally have ANY oiling method other than dripping oil on the wipers.
The one-shot was gonna be a lot of work, and there really wasn't a good way nor room for lines.
I drilled top-side oil holes thru to the top of the carriage V-way and to the side of the flat way, and a shallow hole for press-in flip-top oilers, on front and back ways.
A bit of tubing was required on the back to hit the flat way, since the area over it was too thin in my guestimation to put in a hole. Gibs get oiled by overflow.
Front carriage V-way I scraped some oil reliefs into, leading down from the tip relief.
Much better than before, and a lot less work than the one-shot idea. Oil leaks out under the carriage ends, carrying crud out, instead of wiping it in.
You need pressure and flow regulators on the one-shot, or all the oil goes to the easy spots. You need room to put in tubing. You need pressure fittings, and room for them. You need places to drill passages, and plugs for the right-angle turns where the extra holes are. You need a pump and reservoir.
Pull the ball oilers, and put in flip-tops.
A piece of felt teased out into "fluff" will keep out chips.
Much simpler, if you can do it.
