Valve Clearance
VALVE CLEARANCE SPECIFICATIONS
| Application | In. (mm) |
|---|---|
| Intake & Exhaust (Cold) | .005-.007 (.13-.18) |
| Intake & Exhaust (Hot) | .007-.008 (.18-.20) |
- Disconnect negative battery cable. Remove valve cover and gaskets. Rotate crankshaft until No. 1 cylinder is at TDC of compression stroke. Ensure timing "V" mark on crankshaft pulley aligns with zero mark on timing belt cover. Remove distributor cap and ensure rotor is positioned to indicate cylinder No. 1 TDC. See Fig 2 .
- If rotor is positioned correctly, valves to be adjusted will be closed. If rotor is not positioned correctly, rotate crankshaft clockwise one revolution (360 degrees) to correct position. See Fig 2 .
- Using feeler gauge, measure clearance between rocker arm adjusting screw and valve stem on valves No. 1, 2, 5 and 7. See Fig 3 . Adjust valve clearance if not within specification. See VALVE CLEARANCE SPECIFICATIONS table.
- Adjust valves by loosening lock nut and turning adjusting screw until correct clearance is obtained. Hold adjusting screw while tightening lock nut to 13 ft. lbs. (17 N.m) and recheck clearance.
- Rotate crankshaft clockwise one revolution (360 degrees). Measure clearance between rocker arm adjusting screw and valve stem on valves No. 3, 4, 6 and 8. See Fig 3 . Adjust valve clearance if not within specification. See VALVE CLEARANCE SPECIFICATIONS table.
- Adjust valves by loosening lock nut and turning adjusting screw until correct clearance is obtained. Hold adjusting screw while tightening lock nut to 13 ft. lbs. (17 N.m) and recheck clearance. Reverse removal procedure to install remaining components.
