I've done it both ways, leaving the oil pan on or removing it. Removing the pan is probably the best way to insure a clean leak free job. Leaving the pan in requires some trimming of the timing chain cover, loosening the front of the oil pan, finesse and plenty of RTV sealant.
In order to replace a timing chain for a 2003 Chevy Cavalier, a person will need remove the oil pan, crankshaft pulley and hub, timing cover bolts, and timing cover. Then the timing cover gasket, timing cover and bolts, crankshaft pulley, and oil pan will need to be installed.

Once you reach 100K you're running on or at the limit of life expectancy of the timing chain, chain tension-er, cam chain gear and crankshaft chain gear. All four should be replaced as a set. You will also need to replace timing cover gasket and the crankshaft front cover seal. Cost of parts < $75.00 but not an easy job.
The timing chain is located on the left side of the engine, to access it you will need to take off the manifold cover.
