Stihl 201T leaking bar oil

[Bigeclipse]

All,
I have a 201T which I use only to trim limbs in a trees on a rare occasion (mainly for treestands to be honest). I do not work on saws but I am slightly mechanically inclined. Anyways, I got this saw at an estate sale so have no history on it. It runs well and I have been using it off and on over the past year. It cuts well and runs fine BUT every time I use it, it leaks bar oil. I mean pretty bad to be honest, so what I do now is after each use I drain the saw of the oil so it doesn't leak all over. I am not even sure what to check or where but there is either a crack somewhere or a plug is missing or a line is unplugged or something. Any ideas of what to check and where? Thanks!

Remove clutch and chain sprocket and have a look on the oil pump. Maybe the hose or pump itself is leaking or were the hose connects to the tank housing. The worst case would be a crack in the crankcase.

Thanks. I just checked YouTube and found videos on a ms200 oil pump. Would these be similar to how you would take apart the ms201t?

Yes there all 'fairly' similar but its unlikely the pump is leaking unless the piston rubber seal is shot. More likely the hoses.
