Found three rockers with so much lash that I am surprised I didn't loose the push rods or lash caps. I stopped with the feeler gauges when I was around .085" so they were real loose. I knew something was wrong when I pulled the intake and found three ports dark when the other five were clean. All three were intake rockers on those "dark" cylinders. I was well past the point where I should have run the valves, but this was a surprise since there was nothing to indicate anything was wrong. No noise, misfire, popping....nothing. I will be replacing the lifters anyway, but what else could have suffered? Can't believe this just went a mid 5.8 in this condition.
