Hi my name is XXXXX XXXXX I am going to try and help you with this.
With the engine cold the valves clearance should be:
Exhaust 0.5 mm
Intake 0.3 mm
The adjusting nuts should be torqued to 20 +/- 2 Nm
It should be noted that the valve clearance should be increased by 0.1mm at every cylinder head gasket replacement. The valve clearance should be checked every 500 Hours
Hope this helps. If you have anymore question let me know and dont forget to click "Accept"
