[Shotimes] removing the oil pump

[van Oss]

I am tearing down a 3.0L.  The cam covers, belt, damper, crank sensor, and
the crank timing-belt pulley all are off.  I am looking at the oil pump and
have removed 4 bolts that held the oil pump onto the block.

I have very gently tried to pry the oil pump away from the block.  It seems 
stuck toward --- uh, the rear of the engine  ...  or right side, to you 
traditionalists  ...  or on the left, as you look straight at the oil pump.

By any chance, is there a bolt coming from inside the block?  Do I need to
remove the oil pan to get to that?  Or is there something else I need to do
to free up the oil pump?

Thanks.
