It's 1:05 for the UA-OZ connection or 1:30 for the OZ-OZ connection.

The terminal situation in MNL appears to be a bit fluid. Based on what I read today, OZ arrives in T-1 and PAL domestic departs from T-2 but at some point (perhaps in 2009), OZ will move to T-3 and T-1 will become exclusive Cebu Pacific. But the timing seems a bit up in the air. The stuff I read says that transferring from T-1 to T-2 isn't bad but anything involving T-3 is a 20 minute cab ride.

Maybe it wouldn't be totally crazy to pay to take PAL from ICN if the connection is better and it avoids having to deal with changing terminals in MNL. I'll check that out.
