What's That Sound?

Get a cheap stethoscope, so you can be sure. I had a brand new set of Edelbrock push rods eaten up at the rocker. You need to look at the pushrods, and make sure they are fine. Also, I had the adjuster fail on another engine. Look at the grain of the adjuster. It looks like sand. I put in all ARP adjusters, and haven't had to adjust them.
