Does a timing belt make noise before it breaks?
Because the timing belt is covered in a series of rubber teeth, when they start to wear down, or some of them even break off, it’s not going to run evenly between the camshaft and a crankshaft any longer. That creates a ticking sound as it spins.
What happens if timing belt breaks while driving?
If a timing belt breaks while driving in an interference engine, the camshaft stops turning leaving some of the engine valves in the open position. This may result in a heavy damage to the engine with broken or bent valves, damaged pistons and, possibly, destroyed cylinder head and block.
Can low oil cause timing belt to break?
