?If a timing belt or chain breaks while the engine is running the engine will be severely damaged and some of the valves will probably bend and damage the pistons. A timing best needs to be replaced BEFORE it reaches the end of its life and breaks. Car manuals make this clear.
the ZETEC engine used in the 1999 ZX2 is a non-interference engine. This means that the pistons will not contact the valves when the timing belt breaks. Because of this, the valves will not be bad if the timing belt breaks
The valves could be bent.
it shouldn't but it is a possibility
A shop in Port Orchard, WA says yes
It is an interference engine by design so if the timing belt breaks it will be seriously damaged. The valves will be bent and the engine will need repairs costing upwards of $1500
the timing belt on my 2003 galant broke while i was driving and i had it replaced by the dealer. they said it's possibility for the valves to bend. I had no problems after my timing belt was changed Tony
No , the 1.8 liter 4 cylinder in a 1999 Mazda Protege is not an interference engine
YES THE VALVES WILL HIT THE PISTONS IF TIMING BELT JUMPS OR BRAKES YES THE VALVES WILL HIT THE PISTONS IF TIMING BELT JUMPS OR BRAKES
Before it breaks
According to the Gates website ( they make timing belts etcetera ) The 3.3 liter V6 engine in a 1999 Mercury Villager does have a timing BELT The engine IS AN INTERFERENCE ENGINE So , if the timing belt breaks , engine damage will occur
In short, yes. The timing belt turn the cam-shaft which controls the timing of the opening and closing of the valves in the cylinder head. When a timing belt/chain breaks (usually at high RPM) valves can remain open where they can come in contact with the pistons and be bent by the pistons that are still moving with great force at high speed. Simply replacing the timing belt will not fix the engine if the valves are bent. You can get the valve train re-machined, but an easier (though not cheap) fix is to replace the whole cylinder head.
Yes, the 1999 Kia Sportage with 2.0L DOHC is an "interference" engine, meaning the valves can hit the pistons if the timing belt broke.
