Well I got the knocking sound and then a #6 misfire. Opened up the valve cover to find that my #4 exhaust lifter looks like it came apart inside. Gonna have to pull the head to see how bad things are. Anyone else seen this? These are as good as I could get with the scope I have.
The cam lobe looks much better than this roller. Gonna take a chance and run it. Replacing my injectors while I am this far. They look pretty bad. Do I need to replace the high pressure fuel pump, or any other lines seals in the fuel line? I am replacing the 2 lines that feed from the HPFP to the rails, but not sure if the pump is a replace if removed item. I have my computer back from LS1, so I am hoping my family car will be running in the next few days.
