Can a bad timing chain cause an engine to fail?
3. Engine won’t start or fails. 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.

3. Engine won’t start or fails. 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 does a tensioner do on a Mazda 3?
The tensioners job is to keep the right amount of pressure on your Mazda 3’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 is my Mazda engine making a ticking noise?
Is Mazda Still Refusing Variable Valve Timing (VVT) Repairs? Variable valve timing defects in Mazda L-Series engines are to blame for oil leaks, loose timing chains, and catastrophic engine failure. Owners might first notice VVT problems as a loud ticking noise during startup.
