    I'd be really surprised if the motor isn't damaged in the chain case or that you wouldn't have bent valves. it's possible to do a leak-down test and determine of there's bent valves and you could tear the motor down far enough to see if there's damage in the timing chain case area. Consider a guaranteed used engine if there's much damage. Or you could have gotten very lucky and only lost a chain. Consider that there may be matal debris in the oil pan which could cause problems, too.
