Inliners International Forums General Discussion Engines 250 Chevy, rocker arm nuts backing off.

If the nuts spin on the threads pretty easy,then you should have replaed them.

You can put a thin jam nut also.

You can also buy aftermarket rocker arm nuts that are called polly locks,they have a center allen keyed set screw.
