How do you adjust the valves on a 1984 Chevy Corvette engine?

Answer 1

== == Remove rocker arm covers. Crank the engine until piston #1 is at top dead center (TDC) and is in it's firing position. This is indicated when the mark on the harmonic balancer lines up with the center or "0" mark on the timing tab and the #1 valve is not moving as TDC is approached. You could also remove the distributor cap and verify that the rotor is pointing at or near plug #1. If the #1 valves move as the mark comes up to the timing tab, the engine is in #6 firing position and should be turned over one complete revolution. With the engine in the #1 firing position and at TDC, the following valves may be adjusted: * Exhaust valves 1,3,4 & 8 * Intake valves 1,2,5 & 7 To adjust the valves, back out the adjusting nut on the rocker arm so as to allow you to rotate the push rod with your fingers. Then tighten the nut just to the point where play has been removed and you can no longer rotate the rod with your fingers. Then tighten the nut one full additional turn. Now crank the engine one revolution until the pointer is again at TDC. This is the #6 firing position and the following valves may now be adjusted: * Exhaust valves 2,5,6 & 7 * Intake valves 3,4,6 & 8 Install rocker arm covers.
