1. Disconnect the 2P connector from the VTEC solenoid valve. 2. Measure resistance between the YEL (front) or BLU/YEL (rear) terminal and body ground. Resistance: approx 14—30 ohms 4. If filters are normal, push the VTEC solenoid valve with your finger and check its movement. FILTER Replace. YEL (front) or BLU/YEL (rear) 3. If the […]

Valve Clearance Adjustment NOTE: Valves should be adjusted cold, when the cylinder head temperature is less than 100°F (38°C). Adjustment is the same for both intake and exhaust valves. Adjust valve clearance at TDC of each cylinder. Do not rotate the engine counterclockwise. The tim- ing belt could jump a tooth on the camshaft pulleys. […]

Valve Seats Reconditioning 1. Renew the valve seats in the cylinder head using a valve seat grinder. NOTE: If guides are worn (see page 6-39), replace them (see page 6-40) before grinding the valve seats. 2. Carefully grind a 45° seat, removing only enough material to ensure a smooth and concentric seat. 3. Bevel the […]

Valve Guides Valve Movement Measure the guide-to-stem clearance with a dial indicator while rocking the stem in the direction of normal thrust (wobble method). Intake Valve Stem-to-Guide Clearance: Standard (New): 0.05 — 0.11 mm (0.002 — 0.004 in) Service Limit: 0.16 mm (0.006 in) Exhaust Valve Stem-to-Guide Clearance: Standard (New): 0.10 — 0.16 mm (0.004 […]

Camshafts Installation CAUTION: Valve locknuts should be loosened and ad- justing screws backed off before installation. 1. After wiping down the cam and journals in cylinder head, lubricate both surfaces and install camshaft. 2. Turn the camshaft until its keyway is facing up. (No. 1 cylinder TDC). 3. Set a new O-ring and a dowel […]
