My ms 460 is leaking oil when it lays on its side, seems to be leaking from the oiler or that area. Leaks the whole tank. Any ideas ??
 
It could be the oil tank vent, which is located between the two bar studs. Clean it up real good and remove the sprocket cover, bar, chain, and inner guide plate and tip it on its side. See if you can physically see where the leak is coming from.

It might also be the oil input hose junction where it meets the pump body. Sometimes those get a wrinkle when the oiler is being installed.
