07 Honda crv2.0 Valve Clearance

Can the valve clearance of 7 Honda crv2.0 be adjusted? The method is as follows.

1. First, loosen the fixing nut of the valve adjusting screw, insert the plug gauge with a specified thickness into the valve gap, and turn the adjusting screw with one hand until the plug gauge is slightly resisted. After adjustment, insert the plug gauge into the center of the valve clearance, keep the adjusting screw still, tighten the fixing nut and lock the adjusting screw, and then re-measure the valve clearance with the plug gauge, because the adjusting screw may be inadvertently rotated when locking, so that the valve is closed.

2. Secondly, according to the structural principle of the valve train, according to the ignition sequence and the arrangement sequence of the intake and exhaust valves, the clearance of 4 valves (four-cylinder engine) or 6 valves (six-cylinder engine) can be checked and adjusted. Then turn the crankshaft once so that four or six cylinders are at the compression top dead center position, and then adjust the other four or five or six valves.

3. Finally, it is difficult to remember the order of the intake valve and the exhaust valve due to the different engine valve arrangement order, and the valve clearance can be adjusted cylinder by cylinder according to the ignition order or fuel injection order of the engine. In order to accurately adjust the valve clearance, the intake valve and exhaust valve clearance of each cylinder can be adjusted by using the direction of distributor.
