    This document provides instructions for adjusting the valve clearance on a 1999 Honda Accord LX with a 2.3L L4 engine. The procedure involves removing the cylinder head cover, setting the number 1 piston at top dead center, checking and adjusting the intake and exhaust valves to a specified clearance using a feeler gauge, then repeating the process for the remaining cylinders by rotating the crankshaft. The final step is reinstalling the cylinder head cover.

    1999 Honda ACCORD

    Submodel: LX | Engine Type: L4 | Liters: 2.3


    Fuel Delivery: FI | Fuel: GAS
    Valve Clearance Adjustment
    NOTE: Adjust the valves only when the cylinder head temperature is less than 100F (38C).
    1. Remove the cylinder head cover.
    2. Set the No. 1 piston at TDC. The "UP'' mark (A) on the camshaft pulley should be at the top, and the TDC grooves (B) on the pulley should line up with the top edge of the
    head.
    3. Select the correct thickness feeler gauge for the valves you're going to check.
    Intake: 0.26 mm (0.010 in.)+/-0.02 mm (0.0008 in.)
    Exhaust: 0.30 mm (0.012 in.)+/-0.02 mm (0.0008 in.)
    4. Insert the feeler gauge (A) between the adjusting screw (B) and the end of the valve stem and slide it back and forth; you should feel a slight amount of drag.
    5. If you feel too much or too little drag, loosen the locknut (A), and turn the adjusting screw (B) until the drag on the feeler gauge is correct.
    6. Tighten the locknut and recheck the clearance. Repeat the adjustment if necessary.
    7. Rotate the crankshaft 180 counterclockwise (the camshaft pulley turns only 90). The "UP'' mark (A) on the camshaft pulley should be toward the exhaust side of the head.
    Number 3 Piston at TDC
    8. Check and, if necessary, adjust the valve clearance on No. 3 cylinder.
    9. Rotate the crankshaft pulley 180 counterclockwise to bring No. 4 piston to TDC. Grooves (A) are visible again.
    Number 4 Piston at TDC

    10. Check and, if necessary, adjust the valve clearance on No. 4 cylinder.
    11. Rotate the crankshaft 180 counterclockwise to bring No. 2 piston to TDC. The "UP'' mark (A) should be on the intake side of the head.
    Number 2 Piston at TDC
    12. Check and, if necessary, adjust the valve clearance on No. 2 cylinder.
    13. Install the cylinder head cover.
