If it is a EJ-DE, then nothing at all is variable.
If it is a EJ-VE (probable, could not see it right in the Vid, because you didn't really film the view of the camshafts drive side...) then the Valve timing is variable.


Valve clearance is not variable in both types. To correct that, you would have to change shims on the upper end of each valve.

Shims is compatible or only in daihatsu i found it ?

I don't know. But from what I saw, I guess you'd have to go to the Daihatsu Service Partner to get those.


But: First measure, then go and buy parts, at least, if you don't have to get a complete set. I don't know the details. Never had to do this.
