Stihl 032AV leaks chain oil

When I got this saw from my father-in-law, the case was full of chain oil. I removed the oil pump and replaced the O rings and gasket years ago, no change. I typically leave the oil setting at zero and it leaks enough oil to lube the chain anyway. I don't have a parts diagram, anyone know where or how it could leak? Its quite the annoying mess. To gauge the leak rate, I use a tankful of chain lube almost per tank of fuel with the setting on zero.

Have you looked to see if there is a chain oil line going from the tank on the chainsaw to the pump? Has this possibly rotted out and leaking out through the whole through the tank where it gets taken in and goes through the pump?

I'll be opening it up again this weekend, but from what I remember the pump connects directly to the oil tank and has no hoses. I'll double check it again. I cleaned the carb yesterday and now it will not run unless the chokle is ON. I ordered a carb rebuild kit.

UPDATE: after rebuilding the carb I decided to pull the side off. The area around the oil pump is perfectly clean, no leaks, yet my case is still full of chain oil. There is no oil hose, the pump is connected directly to the oil tank. If I had to guess, I'd say that it is coming out of a gasket between the plate that the pump mounts to and the rest of the saw. I wonder if the oil tank is 2 pieces and the gasket is leaking??

With the clutch off and having access to the pump, I see a bunch of screws that appear to split part of the case. Should I remove these screws and pull out what appears to be the housing that holds a crankshaft bearing? I'm getting into new territory here, just want to be sure before I pull it apart. I can't seem to find any parts breakdowns online.

Before you go that far check the vent,,Iam not sure where it is but these vents are a big problem. It might be in the case and or in the cap itself.
