Re: A rather un-remarkable BMW re-fresh.
I don't recall an o-ring on the clutch pushrod. I'm wondering why you don't want to pull the transmission completely; to get this far, you've already done all the "heavy lifting". That permits a much better cleanup of both transmission splines and the clutch hub splines. And note that for some reason the rubber boot at the rear of the transmission (around the clutch pushrod) is a bit fussy so that it doesn't leak. You just want to make sure it doesn't have any cracks, and that you are only using the correct (original type) clamp, tightened "just enough". I had one of those just about drive me mad once; it persisted in a slow drip (this was on a friend's bike). There's no seal keeping transmission oil from entering that boot, so the boot itself has to seal against leaks.
Of course, if you're working from the floor (and by yourself), I can sort of see why you might be loath to pull the trans. It's important when reinstalling it that you are aligned pretty much perfectly so as not to bend that pushrod.
