After I found out that #2 cylinder is dead and it is firing, I took off the
rocker cover and proceeded to retorque the head/rocker assembly.
The head retorque went well. However, when retorquing the rocker shaft nuts
(to 25 lb-ft) I think I found a problem. After getting it to about 10# or
so, the nuts on #s 2 and 4 just spin. They will spin with no resistance
either forward or reverse. This isn't good. did I do something terribly
wrong or was it time for them to go?
