What happens when intake valve loosens in Honda Accord?

How does an automotive idle air control valve work?

What causes a Honda Accord to have a rough idle?
While you have the valve cover off check the timing belt tension, if you feel a lot of slack this can cause the cam to ‘chunk’ as it spins causing a rough idle. This is because the valve spring pressure pushes on the cam as it rotates past the lobes causing a brief acceleration of the cam.

How does a Honda valve adjustment tool work?
It is here that the Honda valve adjustment tool (or similar) helps. See the picture below to see how the tool would work (my tool has a 10mm socket welded to a hollow tube). The tool allows the locknut to be held stationary when turning the adjusting screw, and the adjusting screw to be held stationary when turning the locknut.
Can a timing belt change cause a valve to leak?
The only connection between timing belt change and valve adjustment is the valve cover which has to be loosened in order to remove the upper timing belt cover. Once loosened the valve cover could leak, so its better to remove it and change the gasket especially if its 10+ years old.
