Valve Clearance Adjustment Acura SLX I

Note. SOHC uses use hydraulic valve lifters, valve adjustment is not required.

DOHC

All valve adjustment must be done on a cold engine. DOHC engines have a tappet fit over valve spring with a shim on top of tappet. The shim is replaceable and available in assorted thicknesses. Shims are available in .0008" (.020 mm) intervals between .0945-.1260" (2.400-3.200 mm) thickness.

To measure clearance, rotate camshaft positioning heel of lobe over tappet. Using feeler gauge, measure valve clearance between adjustment shim and camshaft lobe. Ensure valve clearance is within specification. See VALVE CLEARANCE ADJUSTMENT SPECIFICATION . To adjust clearance, apply engine oil to camshaft lobe and adjustment shim. Using Valve Clearance Adjusting Tool (J-42689), rotate camshaft and push out adjustment shim with flat-blade screwdriver. Measure shim and replace with appropriate thickness adjustment shim to bring clearance within specification.
