It's a pain in the ass on any car. I believe you have to / may have to d/c the engine and tranny, you may have to remove the engine from the car (depending on space) take off the oil pan, oil pump (depending on location; if it blocks the crankshaft), crankshaft bearings, timing chain / belt, crankshaft gear, and anything else that may be in the way.
I did it on a Toyota Camry (4cyl fwd) and it took about two days, and that engine was alot simpler (I think) than the 3.2L motor. PLus there was alot of space b/c the engine bay was made to hold a v6 as well, so the 4cyl had much more area to work with.
But a car that is leaking oil really gets on my nerves; especially if it was my car. I don't htink I could just live with it. It would make me feel like my car is unreliable, falling apart, etc. Of course these are my opinions and are probably more psychologically based than anything else.
The parts required would not be too expensive; you can get kits which will have all the gaskets you would have to replace so that you don't have to buy it piece-meal. On the camry I think it was less that $80 for the kit. Labor is what'll kill you.
