What happens if timing chain tensioner breaks?
A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves.
What can happen when the timing mechanism breaks on an interference engine?
If a timing belt breaks while driving in an interference engine, the camshaft stops turning leaving some of the engine valves in the open position. This may result in a heavy damage to the engine with broken or bent valves, damaged pistons and, possibly, destroyed cylinder head and block.
What happens if the timing belt goes bad on a Toyota Corolla?
The timing tensioner can also go bad. The tensioners job is to keep the right amount of pressure on your Toyota Corolla’s timing belt or chain. As the belt/chain stretches through normal operation, it would get loose and fall off or jump. The tensioner keeps this from happening by keeping a consistent amount of force on the belt.

Why does my car have a broken timing chain?
If so, then the broken timing chain could be the result of lubrication problems stemming from the oil sludge for which these engines are notorious. Supposedly, changing the oil every 5k is sufficient, but depending on the conditions under which this car was driven, every 5k may not have been sufficient to prevent sludge in that type of engine.
What causes a Toyota Corolla to not start?
Engine Won’t Start – If your Corolla’s timing chain or belt has fallen off completely, broken, or has jumped a few teeth, it is entirely possible that the engine won’t even start. You might hear it slapping around as the engine cranks over. If this is the case, the damage is already done.
