AC removal causes oil leak?

[Luis Felipe Patino]

As I mentioned a few weeks ago fixing my
alternator got me started removing the dead ac in
my 4kcsq.

Continuing that job I just removed the compressor
2 days ago, but hoping to lighten up my car to the
max I even took the "angle piece" out (as the
bentley calls the rear compressor swivel, held to
the block by a long and a short bolts). Now my car
is leaking oil.

At first I thought that the culprit was the oil
temperature sender, because I had found it wet and
loose before the compressor removal, and oil drips
from it; however, the AC side of the sway bar and
subframe are soaked, and I remember a bit of oil
having dripped out of the longer bolt holding the
angle piece. Then after spending the night
searching the archives I found "rumors" that one
or both of these bolts actually go _through_ the
block into oil passages instead of what had
appeared to me as harmless dead-end threads.

The rumors are looking pretty true to me now. Are
they or not?

I was thrilled at not having anything between my
oil filter and me. Am I going to have to put the
angle piece back to stop the leak or can I just
put the bolts back by themselves, or replace them
with shorter versions? loctite? did I trash
anything by driving 2 days like that? (tiny oil
loss of ~0.1 L)

TIA
