I'm in the middle of replacing my timing chain. The FSM states that if the oil pan gasket is excessively swollen, replace it at the same time (the bottom of the timing cover rests on the oil pan). If your like me, you crumpled the pan gasket anyway putting the timing cover back on. No biggie though, I'll be dropping the pan and replacing the gasket as a last step anyway, yeah, it'* swollen. If yours is new, and you get the timing cover back on carefully, you will probably be fine.
As far as a low oil pressure problem, did you check it with a oil pressure gauge first? Our sensors and wiring harness' have a history with funky oil pressure readings. Mine went flaky and it turned out to be a broken wire at the oil pressure sending unit.
