What happens if you break the belt on a Lexus?
The Lexus mechanic couldn’t (or perhaps would ‘t) give a straight answer to this question. He only eluded to the fact that if the belt was to break the piston “may” come into contact with the valves and the engine would be toast. I have done the obligatory web searching and have found that everyone under the sun has a different answer for this.

What causes the timing belt to jump gears?
The molded, reinforced teeth on the timing belt engage gears on the crankshaft and camshafts. After many tens of thousands of miles, the teeth can wear or break, or the belt can stretch, thus causing the belt to jump position on the crankshaft or camshaft gears.
When is a timing belt failure bad news?
A timing belt failure is bad news because when the belt breaks, the camshaft stops turning and the engine dies.
When to change timing chain in interference engine?
When timing belt or timing chain snaps occur and the cam stops as a result, the engine remains intact, hence you only need to change the timing chain or belt. On the other hand, interference engines have a short space between the pistons and valves and when the cam stops, the valve surely will break or at least bend.
When to know if your car has an interference engine?
An interference engine is one that has insufficient clearance between the valves and pistons if the cam stops turning due to a broken timing belt. The result is usually catastrophic engine failure. Not so with a non-interference engine. It pays to know. The video below will also help you determine if your car has a timing belt or chain.
Can a broken timing belt cause bent valves?
Interference vs. non-interference engines. The level of damage caused by a broken timing belt can depend on the type of engine you have in your car.
