850 rear main leak

So my 95 855t has started to seep from the rear main, enough so the trans is wet and the steering rack....but it's not a constant drip. The breather system is in decent shape fyi...any gurstimations on time till it blows out? Haha I know that's an impossible thing to guess, when I did the motor in my sis 850 at 200k the rear main was still dry...I drive my carharder than she does. I wanna wait like a month if I can...just dunno...don't some of seep and some of em pop out?

I've not had one blow out, only seep.

Drive it and see.
