What happens when timing chain 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. The valves themselves will bend and potentially ruin the engine.

What causes timing chains to break?

A timing chain can break with either too much or not enough tension. If the chain does not have enough tension, it can develop slack. A chain with too much tension can also fail, as it is placed under excessive stress. Tension increases friction and heat in the chain, which can result in failure.

Will a car turn over if the timing chain is broken?

No matter which type of engine you have, a broken timing chain will cause your engine to immediately stop running and turn off. However, if the timing chain breaks, the piston and valve will collide. The result will be a damaged cylinder head, valve, piston, cylinder, and/or camshaft.

Can a broken timing chain lock up an engine?

A timing chain is supposed to last the life of a vehicle, within reason. But if it breaks, the pistons will come up at the wrong time and crush a bunch of the valves, leaving the crankshaft unable to turn. That would lock up the engine, just as if you had run out of oil and melted the crankshaft to the bearings.

What does it sound like when timing chain breaks?

A lax timing chain, or worse, a broken timing chain with loose parts within the engine, will produce a rattling sound when your car is idling. This rattling sound is typically most prominent while the engine heats up and disappears after some time.
