the first question is what caused the hole? did the timing chain break and hit the cover, second is it a 2.4 liter engine?
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.
To remove the timing chain on a 2.2 Chevy Cavalier, first ensure the engine is cool and disconnect the battery. Remove the necessary components like the engine cover, harmonic balancer, and timing chain cover. Align the timing marks on the crankshaft and camshaft, then unbolt and carefully remove the timing chain along with the timing chain tensioner. Finally, inspect all components for wear before replacing or reinstalling.

The 2002 Chevy Cavalier with a 2.2-liter motor has a timing chain, not a timing belt. The timing chain is located inside the engine, connecting the crankshaft to the camshaft to ensure proper timing of the engine's internal components. Accessing the timing chain typically requires removing various engine covers and components, including the engine front cover.
Sounds like your timing chain broke! Have you actually pulled the valve cover off and looked yet?
next to the timing chain you will find it in the cover on front of engine where the water pump is mounted they call it the timing chain cover you will have to remove this cover to get at it
timing chain is inside the timing chain cover which is located between block and water pump. the water pump mounts to the front of timing case There is a cover that is behind the water pump... The timing chain is under that cover.
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 cover on a 4.6L is the whole front of the engine. drl
The seal on the timing chain cover must be pressed out and the replacement pressed in.
Its on the passanger side of the engine under a black cover.. its is between the belts and pullys and the engine block.
Just taking a guess........Loose chain.
