In the case when a car has an interference engine (Daewoo Lanos), if the timing belt failed, there is a strong possibility the pistons hit valves before the engine stopped completely. First perform a compression test, if the valves are bent they will not seal properly and the compression readings will be low. Keep in mind if the timing belt is broken or not installed correctly, this could cause cylinders to have low compression also. Inspect with a fiber optic borescope through the spark plug holes, look for impressions in the piston tops.
The fiber optic borescope can help by giving an indication of the damage that may have occured without disassembly.
