Valve Lash ADJUSTMENT For Acura?

Valve Lash
The details are as follows :---


Adjust the valves only when the cylinder head temperature is less than 100°F (38°C).
  1. Before servicing the vehicle, refer to the precautions section.
  2. Remove or disconnect the following:

    Negative battery cable
    Air intake tube
    Intake manifold
    Valve cover
  3. Rotate the crankshaft so that the valves to be adjusted are closed and the rocker arm is contacting the camshaft lobe base circle.
  4. Measure the valve clearance. If adjustment is necessary, loosen the locknut and turn the adjusting screw as necessary to achieve the correct valve clearance.
  5. The correct valve clearance is:

    Intake valves: 0.008-0.009 inches (0.20-0.24mm)
    Exhaust valves: 0.011-0.013 inches (0.28-0.32mm)
  6. After adjustment, tighten the locknuts to 14 ft. lbs. (20 Nm).
