What is the valve adjustment size for Renault engines?
1 Answers
In most cases, the intake valve should be adjusted to 0.3mm, and the exhaust valve to 0.4mm. There are two common methods for checking and adjusting valve clearance: 1. Cylinder-by-cylinder adjustment method: Based on the firing order of the cylinders, once the piston of a specific cylinder is at the top dead center of the compression stroke, the intake and exhaust valve clearances of that cylinder can be adjusted. After adjustment, rotate the crankshaft and follow this method to adjust the valve clearances of the other cylinders step by step. 2. Two-step adjustment method: (1) Rotate the crankshaft to position the first cylinder's piston at the top dead center of the compression stroke, aligning the flywheel mark with the inspection hole line. At this point, valves 1, 2, 4, 5, 8, and 9 can be adjusted (referring to the engine valve arrangement from front to back). (2) Rotate the crankshaft one full turn to position the sixth cylinder's piston at the top dead center of the compression stroke, then adjust valves 3, 6, 7, 10, and the "additional two" (i.e., 11 and 12). (3) During adjustment, turn the adjusting screw while inserting a feeler gauge between the valve stem end and the rocker arm, moving it back and forth until a slight resistance is felt.
