Here's The Easiest Way To Adjust Them. First, Get Yourself A Set Of Oil Deflector Clips, And A Valve Cover Gasket. With The Engine At Operating Temperature, Remove The Valve Cover, And Install The Clips On The Rocker Arms On The Pushrod Side. Start The Truck Up. Starting At The Front Rocker, Back Off The Adjusting Nut Just Till You Hear The Rocker "clatter". Next, Tighten The Nut Till The Clatter Goes Away. Next, Tighten The Nut 1/4 Turn At A Time, Pausing 15 Second Between Each Turn To Let The Engine Smooth Out, Until You Have Tightened It One Full Turn. Continue To The Next Valve, And Repeat The Process Till All The Valves Are Done.shut Down The Engine, Remove The Clips, And Reinstall The Valve Cover Using The New Gasket, And Your Done. At This Time It Would Be Wise To Change The Oil And Filter. Check For Leaks, "gunk" The Engine, So Everything Is Nice, And Clean, And Have Yourself A Nice Long Drive.
