Default Found a BROKEN VALVE SPRING

So i opened up my B16A Motor.
Disassembled the Head.
Taking off the valve springs so i could replace the valve seals.
I Found a BROKEN Valve spring.
Luckily for me nothing happened to the motor.


What Could cause a valve spring to break?
Also would this cause low/lower compression in one cylinder?

fatigue over time or possibly imperfections will make them break. Also it Will lower compression if its hanging a valve open. Might have a bent valve now.
