My Timing Belt snapped while I was driving down the freeway. Does anyone know if there is enough clearance between the cylinders and the valves, or should I just look into a major engine job? I drive a 91 Legend.

 

I would check out the valves. There is a strong chance that they were bent.

If you are going to try and fix it yourself, pull off the head and check the pistons first. If the pistons are fine, all the work will be in the head. Check valves, rocker arms, camshafts, seals, etc, etc.
