Pre LAM2? A question; Does it have a threaded rod coming up through the bottom and through the lube reservoir similar to a Lyman 450? I bought a spring loaded plunger setup from casting stuff but my LubeAMatic 2 has no hole in the bottom to mount it.
So,,, no leaks in the bottom?
Similar? Yes.
Mine does, love it.
It has been ten or twelve years since I have actually seen the bottom of my LAM, I mounted it to a section of 2x6 about eighteen inches long (it was handy when I was looking for a board). It does have the rod going though the bottom of the casting, mine has never leaked, so I don't worry about it.

I found this online. The other ones I saw had none. I guess this is an early model. https://uploads.tapatalk-cdn.com/201...5973104c1a.jpg

That would be the rumored but never actually seen in real life, leakless lubrisizer.

The original RCBS lube sizer was derived from the Lachmiller lube sizer and they are painted with the green wrinkle paint. They have a through hole. The lube compression screw passes through the casting from the bottom similar to the Lyman 450.

On my Lubamatic I put some fine valve grinding compound on the threaded rod where it hits the seat, chucked it into my cordless drill, spun it a while and now no leaks. Did the same on a Lyman 450. No leaks there either. YMMV.
Where I do get leaks is through the bottom of the sizing die. Haven't figured out how to clean up that seat yet.

Does it leak with all dies or just one?
I have some Lyman dies with a crummy chamfer that leak. They just need a new chamfer machined with a lathe.
If all of your dies leak you might pulls out your die and melt the lube out to check the seat for damage or some debris lodged there.
A careful machinist could clean up a damaged seat and a poor machinist could scrap your sizer.
You might be able to make long lapping tool with a good seat angle on it. It would be guided by the ram locator bore and you would turn it with some valve grinding compound to lap the die seat.
Naturally you would have to do a very good job of cleaning out the valve grinding compound.
The best lap would probably be cast iron or brass.
