realoem lists this as the bearing cover. What would cause this to leak, just a faulty o-ring?

I don't know what that thing does but it sure looks like a plug to close an old distributor hole...

I guess the original o-ring could get brittle and crack, causing your leak but I am just stabbing in the dark.

anyone else have any input as to wtf this is? there's a pool of oil in it.

I think that is for part of the oil pump drive. Replace the "seal gasket" and be done with it.

Replacing the o-ring will do the trick.

Is this a symptom of too much crankcase pressure?

More than likely the result of an old worn out rubber.......

:D funny man. I was worried because there is coolant disappearing, not from the headgasket(replaced), not from the head(checked and milled 1/1000), not from the heater core(no symptoms of this) but also not externally. But that's a problem for another thread.

Better do the o-rings (upper and lower) on the #11 pipe that connects the valve case to the oil pan- they go too- all these o-rings are under positive pressure, I wonder how they manage forced induction...

And whilst you are at it, preventative maintenance would dictate you do the o-ring on the oil filter housing at the same time.

Else you fix one and the rest get the pressure- and have to do them each week after tha last until they are all done... such unexpected chains of disaster that plagues the uninitiated on such matters run thick with old Bimmers... this is all stuff that should be done regularly (is it in the TIS I wonder- or is it past 250,000 so they don't list it...)
