OK, here's the damage. This is the Cylinder 7 exhaust spring. What's left of it anyway. It is the only broken one I've taken off so far. 7 intake is good. I'll get the spring mic and measure installed height later this week. I can see that the outer spring of Cylinder 3 exhaust is also broken.
There are no color markings on these springs anywhere to tell me what springs they actually are.
