OK guys I finally broke my timing belt on my 90 integra LS while driving home
from work. Mechanic wanted $650 for new timing belt and water pump with no
guarantees since there could be more engine damage. According to the mechanic
the only way to see if there is further damage is if I paid for the replacement
of water pump and timing belt to diagnose serious engine damage which could
cost around $2000. Is there a way to find out if the engine is worth
repairing before I waste $650?

Thanks
