This won’t help the OP but this thread points out that engines with timing belts have a mile limit (Often 60,000 miles) where the belt has to be replaced or THIS will happen. I understand the OP is a student with limited funds but when you ignore the manufacturers maintenance recommendations, especially on an item this important, you’re playing with fire.
This engine is toast, the car is too old to justify putting much money in it. If you could find a junkyard engine and a GOOD buddy who could install it, then maybe it’s worth a gamble.
