Is It Worth Fixing a Broken Timing Chain?

A timing chain doesn't need to be replaced unless there is a problem with it. Is the timing chain immune to mechanical failures? The simple answer is No, it is not. Timing chain problems are not uncommon, especially in high-mileage vehicles.

Can a broken timing chain ruin the engine?

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.

How much does it cost for timing chain to be fixed?

Timing chain replacement can cost between $413 and $1,040. The cost is high due to the complicated nature of replacing this part. If you want to DIY a timing chain replacement, the parts will cost $88 to $245. However, this is a task best left to those with ample experience working on cars.
