Jonsered 2094 oiler leaking

[gekko]

the oil pump on my 2094 is leaking somewhere,

its getting oil to the bar but very little and it leaks out from behind the pump.
the only places i can imagine its leaking is where the pump output goes into the passage to the oiler hole, and there's a little ball right below the input on the pump that looks like a one way valve but i don't see it on any IPL's or service manuals, could it be leaking?

I would doubt that. Looks like the same oiler thats in my 394. I would take all the moving parts out and clean them up and replace the little rubber seal 501 28 85 01 and make sure the tank vent and the oil passage are clean.
