I have a couple tree victim 372's in the shed with good oilers on them. just have to go and pull one. the line and grommet will be here on Tuesday next week. other than pulling the oiler and sitting staring at it for a while I haven't tried anything. ;D it's neat watching oil flow with no help :) i'm easily amused. :D

Video so we can see and be amused too.   ;) :D ;D

I would put a new vent in there. They are cheap or use one from your parts saws you have on had. If you hold the little ball in does the oil flow slow down or stop. If it does I would say the vent and not the pump. I have had bad pumps that wouldn't do what you are saying.

the vent seems to work properly. however I did order a new one. for $1.50, I won't risk ruining one taking it out  :)

Defies physics it seems. Fluid can not flow above it's level without pressure behind it. This is not a syphon senario, and happens even with cap off. Even if the pump was gutted of internals, and leak free to the outside,  oil level in the tank below the discharge port will not mysteriously leak from the port without pressure inside the tank being greater than on the outside. ie. cap off.

well one thing I've learned over the years is sometimes things just don't make sense. the laws of physics can be thrown out the window more times than can be explained.
I've worked with many fluids/liquids that will (given the opportunity), will flow up hill to empty a pail, bowl or bottle due to their 'ropey' bond structure. you get the stuff flowing and it will pull itself up and over (sometimes at great distances), and thick chain oil is no different.
one liquid that comes to mind is any 'flocking' agent. you can have a 5gal pail full of it, start pouring it at a sharp angle, then set the pail back down on it's bottom and it will empty itself out. you need to tip that bucket back and stop the flow. egg white will do the same thing.

at any rate, changed the line and grommet and it still wanted to come out of the port. also changed out the vent with a new one. ended up switching the oil pump out with a good used one and the problem went away. threw the suspected pump on the parts saw and can't get it to show the same issue. so I guess when I get around to fixing that saw up, I don't have to worry about the oiler dumping oil all over the shelf. maybe. we'll see after it runs for a while. ;)
