Broken Valve Spring
I have a Superformance cobra, built in 1996, with a 460 crate motor. This past Saturday, I was pulling into my neighborhood and I heard a terrible noise. I limped it a few hundred feet to get it into the garage. After some diagnosing, I found a completely shattered valve spring, maybe 7 or 8 pieces. I was able to find the keepers and what was left of the seal. I have some new springs and seals on order. My biggest concern is that I can’t get the valve to move. It appears to be in the closed position, with everything off of it (rocker arm and spring seats removed), but I can’t get it to budge even the slightest bit. I have given it some light taps with the lead hammer, but it seems pretty stuck. I guess my main concern is if the valve could have bent, below where it sticks out of the head. Has anyone experienced anything like this?
