Valve adjustment
 

I have a 88 GMC K1500 with a 5.7L and I just finished head gaskets in it.
After adjusting the valves by the book, the right side has a ticking sound.
I followed the servive manual, set to number one firing and adjust the following, Exh. 1,3,4,8 Int. 1,2,5,7. Turn motor one turn and adjust Exh. 2,5,6,7 Int.3,4,6,8.
I turned rocker nut one full turn after lash was gone.

Can someone tell me what the ticking might be?

Thanks

After you ran it you should do it all over again. Does it sould like its coming from only one or both sides?

its messy, but I usually adjust them while its running for a final checkout. if you have a extra valve cover cut the top out and it will contain the oil better.

most of the time I only adjust 1/2 turn after the tick is gone, there was a issue years ago with the cams loosing their lobes when adjusted to 1 turn, I changed to a 1/2 turn and done so ever since.

It's only coming from the right side. The left side sounds great!
I have adjusted valves while the motor was running before, but I felt I would try it with it not running.
So, I should adjust them again?

Thanks

I would back each one off a little until they click and then tighten until the noise stops and then turn a 1/4 turn more. This is done while the motor is running, and you do one at a time.
