1970 Ram Air III stock - noisy valve rocker
I have a stock, never rebuilt, 1970 Ram Air III 400 with roughly 70,000 miles.
I believe it has a noisy valve / rocker. My understanding of the RA III motor from 1970 is the rocker arm retaining nut is torqued to 20 ft-lbs with no adjustability. Before I pull valve covers off and look for a noisy rocker, what can I do even if I do find one that is noisy? Is my only option to check the torque on the nut to see if it's loosened up? Thanks for the help |

Thats about it.
Changing the culprit(s) over to adjustable rocker nuts likely won't resolve anything in the rattle department. Bottomed Out - is - Bottomed Out , on the stud. probably will end up being a lifter or cam lobe. Or both [unrelated] Also probably about time to replace the timing chain/gears |
