B18C Valve Clearance Adjustment – Integra ’94-01

by NinjaX on June 18, 2010

B18C valve clearance adjustment applies to Acura Integra 1994-2001.

Warning: Only rotate engine in direction of normal rotation (counterclockwise as viewed from front of engine). Clockwise rotation may cause timing belt to jump camshaft pulley teeth.

Valves lash adjustments should be done cold, when cylinder head temperature is less than 100°F (38°C). Adjustment procedures are the same for both intake and exhaust valves.

  1. Remove valve cover. Rotate crankshaft counterclockwise so No. 1 piston is at TDC of compression stroke. Ensure UP marks on camshaft sprockets are at top pointing up, and TDC grooves on pulleys are aligned with TDC mark on back cover.
  2. Adjust valve clearance on both valves for No. 1 cylinder. Loosen lock nuts. Rotate adjuster screw until clearance is as specified. Tighten lock nut to 15 ft. lbs. (20 N.m). Recheck adjustment. See valve clearance specs table.
  3. Rotate crankshaft 180 degrees counterclockwise (camshaft sprockets turn 90 degrees) until No. 3 piston is at TDC of compression stroke. UP marks on camshaft sprockets should point to exhaust side of cylinder head. Adjust valve clearance on both valves for No. 3 cylinder.
  4. Rotate crankshaft 180 degrees counterclockwise until No. 4 piston is at TDC of compression stroke. Ensure UP marks on camshaft sprockets are pointing down. Adjust valve lash clearance on both valves for No. 4 cylinder.
  5. Rotate crankshaft 180 degrees counterclockwise until No. 2 piston is at TDC of compression stroke. Ensure UP marks on camshaft sprockets are pointing to intake side of cylinder head. Adjust valve clearance on both valves for No. 2 cylinder. Install NEW valve cover gasket. Install valve cover.
