Question

Quizplus · Accepted Answer

Basket-type coil springs are installed with the tighter part of the coil against the head to prevent the spring from collapsing when the valve is closed. Grinding a valve seat will not affect the installed height of the valve spring because the installed height is determined by the length of the spring and the amount of preload applied to the spring.
