A broken timing belt on ANY engine *could* destroy the engine.
Keep in mind that the purpose of the timing belt is to synchronize the opening and closing of valves with the motion of the pistons. If a piston is rising toward the top of the cylinder and a valve is stuck in the open position (valve protruding down into the cylinder) because that was its position when the belt broke then the two parts could meet in a very bad fashion. This will almost certainly damage the valve, may well damage the piston, could damage the head, could possibly even damage the block.
Given the range of what could go wrong in such a scenario no real determination can be made until at least the heads have been removed. Take the heads off and keep your fingers crossed.

It can, but 95% of the time with this engine, it bends the exhaust valves. They tend to be the first victim. If your engine was running at high rpm, it could also damage the head and the piston. I've seen one engine where it broke the valve off and it flew around in the cylinder -- needless to say, the entire engine was toast. But, most of the time, pulling the head and replacing the bent exhaust valves is all that's required. I say "all", but that isn't a cheap repair. Most run anywhere from $900 - $1300 , depending on how many valves were actually bent. Your best bet ----- change that belt before it happens.

Yep. The timing belt "cases" the circulation of mechanical factors on the concern of piston place. whilst the piston is on the "right" the valves are closed as there isn't any room for valves to be open. If a valve is open, the piston will hit it end of tale. I actual have seen it the place the valve no longer in basic terms bent, however the piston replaced into broken open as properly. as a results of fact of this they advise the belt replace each and every maximum of miles (60-80,000) to decrease the likelyhood that the belt will destroy(and that they'll destroy) besides the undeniable fact that it somewhat is greater much less high priced to substitute a $20 belt than to substitute valves and different factors as a results of belt breakage.

Yes , its an interference engine. It may not destroy the engine if it was reving up.

yes it could destroy the crankshaft
