Alfa 164 Engine Rebuild?

[BahnStrmr6@domain.elided]

Hello.  Looks like my "pristine, beautiful" Alfa 164 that I bought a few 
weeks ago may need an engine rebuild.  The oil pressure is about 10 when it 
is at idle warmed up.  Has anybody had any experience with rebuilding the 164 
engine?  I am mainly wondering how much it costs.  I'm hoping that I can put 
on a new oil pump, and that will help.  Any info would be appreciated.
