Can I change timing chain myself?

Every car has a timing chain. It is the connection between the camshaft and the crankshaft. … And just like any other car parts, changing a timing chain is required. But you can do the job all by yourself if you have the right tools, some mechanical know-how, and a service manual.

What happens if the timing chain is off?

When a timing chain is loose or stretched, you might experience misfires while driving because the timing between the valves and pistons is out of sync, which affects the combustion in the engine.
