I have a 1.9l with low oil pressure.  Is it mostly due to the con rod
bearings, or is it also main bearing wear?  Would rebuilding the rods alone
be worth doing, especially since main bearings are hard to find?  Can this
be done without splitting the case, or must you still do that?  I would
hate to tear it down that far and not do the main bearings.  If you only do
the rod bearings, how can you tell if the crank is still OK?  Do the cranks
not wear very much?
Just wondering and biding my time.
