Hi,

This is my 4g13p, i hear some knocking sound like "dak dak dak" occur, isn't that is coming from the valve clearance problem?
i had adjusted my valve clearance in hot engine with the Inlet valves - ------0.20mm (0.008 in)
Exhaust valves-----0.25mm (0.10 in). please advice me thanks..
Here is my youtube link for my engine..

Beside this may i know play with the marking of cam? The picture that i inserted show the valve clearance that adjusted with the cam in the marking mark, need to adjust the red circle valve.The problem is when i need to adjust the valve marked arrow in the picture, how do i need to turn the crank n make it accurate from the cam in marking turn 180 clock wise?
