It all depends on the engine design. It may do no damage or it may bend valves.
If it is an interference engine valves can bend when hit by the pistons.
yes it will cause valve damage and will need new gasket kit for it when replaced will cost 0ver 1000 to fix
cause
wrong timing can cause any engine to over heat. in fact if the timing is off it can cause hundreds of dollars of damage.
Why would a timing belt jump time and cause damage to the cylinder heads ?
most snapped timing belts will in most cases cause engine damage,the only exception would be a freewheeling engine were valve to piston contact would be minimal an interference type engine would cause damage.
No, the '99 Toyota Camry has a non-interference engine, where the piston and valve path do not interfere with each other. The timing belt breaking will cause your car to stop working, but will not cause valve damage.
Not likely but it will wear the tires out.
On an interference engine the pistons can hit the valves. That will cause severe internal engine damage.
No, it is a non-interference motor
A timing chain, that needs to be replaced, can cause your engine to run rough and lose power. A broken timing chain can cause significant engine damage.
On older 300ZX's equipped with a timing belt it will cause internal engine damage if the belt breaks as they are interference engines.
