ID Request: Brown Stuff Leaking from Crack (PICS)

Ok so for the past unknown number of years, this brown sludge has been slowly emerging from what I assume to be a hole of some sort. This is what has come out the past couple months since I wiped it last:

This is an old piece of machinery made out of very thick steel plates welded together. Right next to one of the weld seam there is this weird sludge that mysteriously appears.
I assume it is water based or at least it oxidizes the iron in the steel and causes rust.
It is slightly sticky and smells a little bit like molasses.
It is pretty firm except right where it comes out of the hole where it has the consistency of mud.
When I burned it with a propane torch it didn't catch fire but did carbonize and leave behind black and white ash. There wasn't much smoke and what smoke there was didn't really smell like anything.
It didn't readily dissolve in wd40, isopropanol, or acetone.
---
I am stumped as to what it is and nobody I have asked has any idea. Can you help me?
I can answer any questions or even provide a sample if anyone required it.

Not sure really but if I had to guess I would say some sort of old adhesive or protective foam of some kind that degraded over the years.
I know it happens with certain vintage musical equipment and the adhesives/ foams need to get cleaned up and replaced.
Finding out what the machinery is would probably help, could be a lot of things possibly.

It is a material grinder for plastics. There is a small cavity behind this spot where I can't get in without drilling a hole, but this stuff only comes out this one spot which would be at the very top of where that cavity would be. It has been doing this for years.

That is strange, not sure what else it would be but there must be a lot of it if it has dripped out for years...

It's almost like it is oozing out of the metal itself, as there is no visible hole or crack there, though the metal is corroded from this substance.

I can think of a few things. Heat causing humidity inside the machine. Does the grinder use any kind of lubricants during the process? Old grease maybe? From a bearing... Or even the actual plastics themselves getting up inside it, mixing together with whatever else and being forced out. It's hard to say really, it's probably a combination of things. What is directly behind the plate?

I thought of that. It doesn't seem like any component of grease, especially since it causes rust.
Some plastics do break down into oils, and contain water, but what puzzles me is that even if plastic were to get into this cavity, why does it not leak out from the inside the same way it went in.
Behind the plate is the vertical chute right above the blades, and there is a little triangle hump that is to bottleneck the chute a little at that point. I assume there is some empty space inside this hump because it is not reflected on the outside.
This issue with this theory that plastic is getting in there is that the inside is spotless, shiny, unpainted steel. There are no moving parts there, and not very much heat, no rust whatsoever.
Also the substance sort of comes out right on the edge of the plate, not the seam between the two plates. That is what kinda has me baffled.
I think I am gonna clean it off real well, and try and watch it regularly so I can pinpoint better exactly where it originates from.
