There are two kinds of car engines: interference engine and non-interference engine.

In the non-interference, the distance between the pistons and valves is quite large. When timing belt or timing chain snaps occur and the cam stops as a result, the engine remains intact, hence you only need to change the timing chain or belt.

On the other hand, interference engines have a short space between the pistons and valves and when the cam stops, the valve surely will break or at least bend. A failed timing chain will be signified by clanking noise. If you hear this sound when your car is on the move, it’s time to replace the timing chain.

Car owners are recommended to have a timing chain or belt changed every 60,000 km. Down below, we make a list of non-interferences and interference engines, check it out!
