What happens when the cam belt breaks on a car?
They open and close in time with the pistons going up and down to let fuel in and gas out. The cam belt links these valves to the pistons – if it breaks the pistons can hit the valves and do a lot of damage and that means opening up the engine.
What happens when a cambelt breaks in a Renault?
This is a picture of the valves from the above engine,you can see that the left hand valve has moved one way,the other valve is obviously bent as it’s not closed properly….
What happens when the timing belt snaps on a car?
In a non-interference engine, the pistons and valves don’t occupy the same space, so if the timing belt snaps, no valve or cylinder damage occurs. You just pop a new belt on, and the engine should theoretically drive normally.
Why do I hear a noise when my timing belt breaks?
From sheer inertia – no matter how fast you were going or even idling – the crankshaft will continue to move the pistons up and down for a short time and will hit the valves. Most likely, a few if not all valves will be bent and typically, you will not hear any type of noise associated with that.
What happens if you have a broken cam belt?
Broken pistons and valves – a completely broken belt means that the camshaft and the crankshaft will become desynchronised, resulting in the pistons coming into contact with the valves as they open, damaging the valves and pistons. If you know the belt is gone – then this is a very good reason for turning off the engine immediately.
Can a broken timing belt cause engine damage?
In a non-interference engine, no matter how low the valves go, the piston will not make contact. Internal engine damage is unlikely. A good mechanic can diagnose if the engine can be repaired, or if a new engine or used engine is needed. Or if the car should be scrapped.

Which is more important the camshaft or the timing belt?
Let’s state it plainly – nothing is more important than the timing belt. It drives the camshaft, which is what keeps the valves synchronized, and the crankshaft, which controls the pistons. Your timing belt tells the pistons when to rise and fall, and the valves when to open and close.
