My timing belt broke while driving on the freeway. Nothing was damaged. I think that I was lucky though.....
it won't slip, it will break if anything, and yes it will bend the valves
The 1.8 liter - 4 cylinder is NOT an interference engine , but the 2.0 liter - 4 cylinder is an interference engine
The timing belt is what keeps the valves from moving in synch with the pistons. If the timing belt snaps or cogs over the pistons are likely to collide with the valves smashing them both.
Ha yes timing belt breakage in any car can cause damage to the engine... things like bent valves, scored cylinder walls and possible engine failure. That is why the idea is to replace timing belts before they break.
If it is an interference engine the valves can bend/break.
Underneath the dash on drivers side, just above the parking break release.
why did my timing belt break on my pontiac 1.6 1993 motor also will the valves be bent because of that
No it does not, it is a non-interferenceif the timing belt break the valves will not collide into the pistons.
If your timing belt were to break while the engine is operating, the camshafts would be out of time with the crankshaft. This 'out of time' would cause the valves to open at incorrect times in regard to the crankshaft/pistons. This break in the timing belt could cause valves to bend or break as well as damage the head itself; pistons could also become damaged in the process.
It can if the pistons hit the valves while they are open. The timing chain ensures that when the piston is at the op of it's storke the valves are closed. When the chain breaks the cam stops turning allowing the valves to open and close so if the piston is still trying to travel up in the cyclinder with the valves open it will hit them and bend or break them. Also trying to start the engine with the timing change broken can have the exact same result.
The timing belt turns your camshaft which opens and closes the valves. If you have a non-interference head your engine will crank. If it doesn't then your valves will smash into your piston heads and something would have to break for it to turn over.
on some engine designs when the timing slips or is wrong the valve train will hit the pistons. something has to break, the valves, pistons, or the rods will bend.
