Help! No compression in #4 Wanted to see if you guys could help. I have no compression in #4.
We pulled the valve cover off and found a broken spring. Replaced the spring and still no compression. Checked the push rod (only #4) and it was fine. What do I check now? Do I need to check all the pushrods? This is a LS6 with heads and cam. I'm new to this and just learning. How far should I go by myself?

You have a bent valve. I just went through the same thing. Take the head off and send to a machine shop. They will most likely replaced the bent valves and clean up the seat if not to damaged. It happens, most likely not the end of the world.
