I was making a pass on Saturday 11/4 and could get only about 5400 rpms. I came off plane and noticed I had lost one cylinder. While I was being towed in, we looked @ the plugs all good, Then we removed the valve cover and all the springs were good ,Then found number 2 exhaust rocker arm loose and the push rod missing the ball on the end. The push rod was still in place and under the rocker arm. As you can see in the attached pictures the top of the rod was damaged and the rocker arm was also. The question is what do you think caused this? Hopefully the damage in confined to the push rod and rocker. 489 procharged 5 lbs boost ran 5800 on lunch run 10/20 ran fine until yesterday.http://www.***boat.com/image_center/...prings-med.jpg http://www.***boat.com/image_center/...damage-med.jpg http://www.***boat.com/image_center/...sh_rod-med.jpg
