Hi fellas, I did a running valve adjustment on my hydraulic flat tappet equipped Pontiac 326 today. I had installed Chevy 3/8-24 self-locking nuts on each rocker stud and adjusted each about 1/4 to 1/2 turn of the nut after ticking stopped and it sounds great. Here's my question. I have one single valve (#2 intake) which after I shut down the engine and right after startup will tick for about 2 seconds then go quiet like the rest. I started and stopped the motor several times today with the same result. Ever have this happen?
