belt breaks while running

The simple answer? NO INFORMATION: An engine running at aprox 1500 rpm means the pistons are traveling up or down about 13 times every second The timing belt keeps the engines valves & pistons synchronized. As the piston comes up , the valve is closed . As it goes down it opens. Never coming near each other. If a timing belt brakes on an engine, the engine suddenly loses BOTH compression & ignition at the same time causing the engine to stall. The valves in one or more cylinders may remain open due to the broken belt. And if the engine takes just 1 second to stop, then the piston can strike a valve over ten times. this is called "interference engines" The Toyota "GAS engines" 1.6 liter and smaller engines were "interference engines". All Diesel engines are unfortunately "interference engines". here is a list by ARGO automotive Toyota 1.5L (1A-C, 3A-C & 3E) Interference 1.5L (3E-E & 5E-FE) Non-Interference 1.6L DOHC (4A-F & 4A-FE) Interference 1.6L DOHC (4A-GE & 4A-GZE) Non-Interference 1.6L SOHC Non-Interference 1.8L Diesel Interference 1.8L DOHC Gasoline Interference 2.0L Non-Interference 2.2L Diesel Interference 2.2L Gasoline Non-Interference 2.4L Diesel Interference 2.5L Non-Interference 2.8L Non-Interference 3.0L Inline 6 (Except 1998 2JZ-GE) Non-Interference 3.0L Inline 6 VVT-i (1998 2JZ-GE) Interference 3.0L V6 Non-Interference 3.3L V6 Non-Interference 3.4L Non-Interference 4.7L Interference http://www.agcoauto.com/content/List_Of_Interference_Engines
NO! ***The simple answer?*** It's a simple question!!! ... After all that, what IS the final answer here?????
Your answer was fully informational...I appreciate it very much, I knew I could run a compression test and get my answer but you just saved me some time... thanks a lot
