Recently adjusted my lifters on the 261 in my 1942 dump. I did them while running,(tighting a few turns then lock them down)to quiet them down, now I'm reading a "noisy lifter is a happy lifter". I feel that not knowing the condition of the camshaft, setting with feeler gauge would be useless.The truck is not on the road yet,and runs great in the driveway. Will running condition change with a load on her from street driving? Can i do damage to the pushrods?. When running with valve cover off, I can see the pushrods are rotating. Can I feel confident that no damage will occur?
