If your timing chain broke because of wear, that means that the engine is probably just as worn. When timing chain breaks on almost any engine, you can be sure that valves are crashed (hit the top of the pistons) and the engine should just be replaced. Do not try to fix it.

replace with an used engine is youour best bet, take it somewhere else this car is simple there is no need for a connpression test to check the chain other than to charge your for it,
