It turns out, I found the answer to my question at

Timing belt-equipped car engines can be classified as either free-running or interference, depending on what occurs if piston/valve synchronization is lost due to a failed timing belt. An interference engine usually sustains damage if synchronization is lost (because the piston can come in contact with the valve). This could result in very expensive engine repairs.
Apparently the 1998 Acura 2.5 TL is an interference engine.
