Measuring Valve Clearance
- Remove accelerator linkage, upper timing belt cover and cam cover. Turn crankshaft clockwise until cam lobes of cylinder to be adjusted point upward.CAUTION: Never use camshaft sprocket attaching bolt to turn camshaft, as this may stretch timing belt.
- Using a feeler gauge, measure valve clearances of each cylinder in firing order sequence of 1-3-4-2. If clearance is not as specified in "Valve Clearance Specifications", adjustment is necessary.
