The rocker arm torque specifications, for your 1990 4.3 liter Chevrolet engine, is 15 pounds per square inch. The rocker arm should be torqued in five pound intervals.
By removing the valve cover from the engine, then removing the rocker nut on the bad rocker. Refer to a technical manual for torque specifications, as this must be properly torqued!!!
The rocker torque sequence is 10 6 3 9 15 11 4 1 7 13 16 12 5 2 8 14 THE TORQUE IS 16FT/LB BUT ONLY 9FT/LB FOR THE LITTLE ONES AT THE DISTRIBUTOR
Gotta have the correct torque specifications and tighten those nuts on the spring assemblies. Too tight,and they don't flutter right. Too loose,and they allow the rocker arms to wiggle out of whack. My apologies for not being more specific,I'm just a 'driveway mechanic'. You need to replace the locknuts for the rockers. I'm not sure if they are positive stop or not.
