Hello, I have a K24Z7 in my 2012 civic SI with 155k, and the vtc is making noise when starting up. I have read mixed comments on it, and am not sure if not fixing it will harm the engine or not. Some people say it will not, and some people say it will. Anyone have any inputs or experience of it causing engine problems? I just don't want to waste the money if I do not have to. But I also don't want to not do it and then have major engine issues in the future.

Thanks in advance!
