Came off turn 2 tonight in hot laps car started missing. Pulled valve cover and #3 intake rocker is not moving at all. Pushrod is there can't tell yet if its bent or whats up. Is it possible the lifter broke or the cam lobe broke? If cam broke the other valve train would not work, correct? #3 exhaust is very loose also. I know i will have to pull the head to see for sure. Just wondering if anyone has had this problem before?
