Well, about 5 months ago i start to hear a tick coming from the valve cover, after asking some questions and doing a bit of research I was happy to know that it is a common problem with a simple solution: Remove the upper guide. I removed the valve cover to find the upper guide already removed.

It seems that the timing chain is rubbing against one of the lower side guides,
How bad of an issue is this? anything i can do about it? the sound is pretty damn loud sometimes.

edit: Ka24de to clear up any confusion

Thanks.
