What are some of the common signs of mis-adjusted rockers? Also how often SHOULD this be checked?

The 24 valvers require adjustment at 100k, If I remember right the 12 valvers need attention every 30K, You can hear the rockers rattlin when adjustment is needed, you dont want to set the valves to tight, set them to spec and if they are so tight that the valves wont completly close you will burn the valves and ruin them. has some excellent info on his website about this. Check it out Here And a big thank you to .
