Rabbit Convertible L4-1715cc 1.7L SOHC (1982)
Valve Clearance: Adjustments
TO ADJUST VALVE CLEARANCE:
-
Valve clearance should be measured with the engine warm. Coolant temperature should be at least 35°C (95°F) or the engine should be at least
warm to the touch. The clearance changes with engine temperature, so more precise adjustment is possible when the engine is warm. Because it
may be necessary to adjust the valves when the engine is cold, such as after cylinder head repairs, specifications for both hot and cold engines are
given.
1. Remove the cylinder head cover.
2. Using a socket wrench on the crankshaft vibration damper bolt, hand-turn the crankshaft clockwise until both the No. 1 cylinder's cam lobes are
pointing approximately upward (valves fully closed).
NOTE: No. 1 cylinder is the one closest to the camshaft drive belt.

Checking Valve Clearance
3. Measure the valve clearances. Insert feeler gauges between the cam lobe and the adjusting disc on the top of the cam follower. Compare the
measured clearance values with the specifications given below.
