Hi
I agree with you nitroholic and this is why I was asking the all the question.
That's is why I thought the holes where blocked but they was not.
But I can say that if I screwed the cap on with any of the shock sticking out, then there was no why of the shock going back in all they way.
The only way the shock goes all the way in is the when you push the shock all the way in then screw the cap on.
Now I don't know if I have a problem with the shock or the oil is wrong (came with car no idea of weight as it does not say on it)
I did read somewhere that depends on where you have shock sticking out before you screw the cap on that is the rebound setting but I don't know.
Thanks
