How to adjust the valve clearance of Great Wall m4?

Very simple, you can refer to the following steps. It is recommended that you adjust the valve when the engine is cooling.

1. Remove the valve cover.

2. Place the piston 1 in the top dead center (TDC) position. The "UP" mark A on the camshaft sprocket should be at the top, and the TDC slot B on the camshaft sprocket should be aligned with the upper edge of the cylinder head. ...

3. Check the valve and select a feeler gauge with appropriate thickness (please refer to the maintenance manual for specific clearance).

4. Insert the feeler gauge between the adjusting screw and the end of the valve stem on the cylinder, and slide it back and forth, feeling a slight delay.

I can't remember the details. You can search online, or go to the repair shop to ask the master for help.

I hope it helps you.
