Valve Clearance: Tercel
- Check and adjust valve clearance with engine at normal operating temperature. Remove valve cover. Rotate crankshaft pulley and align pulley groove with "0" mark on timing belt cover to set No. 1 cylinder at TDC of compression stroke.
- Ensure rocker arms on cylinder No. 1 are loose, and rocker arms on cylinder No. 4 are tight. This indicates TDC compression for No. 1 cylinder. If rocker arms are not as described, rotate crankshaft 360 degrees and realign timing marks.
- With cylinder No. 1 at TDC compression, measure valve clearance between camshaft lobe and rocker arm using proper thickness feeler gauge. See Fig 1LVE CLEARANCE SPECIFICATIONS table.
- Rotate crankshaft 360 degrees and check clearance on remaining camshaft lobes. See Fig 1ust valve clearance, loosen lock nut and turn adjusting screw. After proper clearance has been obtained, hold adjusting screw stationary and tighten lock nut. Recheck valve clearance. Install valve cover.
