2. INSPECT CAMSHAFT TIMING VALVE ASSEMBLY
| (a) Check the stroke of the plunger in the center of the camshaft timing valve assembly. Standard Stroke: 2.2 mm (0.0866 in.) or more HINT: When pressing the plunger, there may be a stepped feeling. This is not a malfunction. If the result is not as specified, replace the camshaft timing valve assembly. | |
