  Q: How to check and adjust valve clearances on Acura Integra?

  A: Valve clearances generally do not need adjustment unless valve train components have been replaced, or a valve job has been performed. The simplest check for proper valve adjustment is to listen carefully to the engine running with the hood open. If the valve train is noisy, adjustment is necessary. The valve clearance must be checked and adjusted with the engine cold. Remove the valve cover. Place the number one piston at Top Dead Center (TDC) on the compression stroke. With the engine in this position, the number one cylinder valve adjustment can be checked and adjusted. Start with the intake valve clearance. Insert a feeler gauge of the correct thickness between the valve stem and the rocker arm on single overhead camshaft (SOHC) engines or an intake camshaft lobe and the rocker arm on dual overhead camshaft (DOHC) engines. Withdraw it; you should feel a slight drag. If there's no drag or a heavy drag, loosen the adjuster nut and back off the adjuster screw. Carefully tighten the adjuster screw until you can feel a slight drag on the feeler gauge as you withdraw it. Hold the adjuster screw with a screwdriver and tighten the locknut. Recheck the clearance to make sure it hasn't changed. Repeat the procedure on the other intake valve, then on the two exhaust valves. Rotate the crankshaft pulley counterclockwise until the number three cylinder is at TDC. Check and adjust the number three cylinder valves. Rotate the crankshaft pulley counterclockwise until the number four cylinder is at TDC. Check and adjust the number four cylinder valves. Rotate the crankshaft pulley counterclockwise to bring the number two cylinder to TDC. Check and adjust the number two cylinder valves. Install the valve cover.
