I agree, if you decide to do this yourself replace it all, tensioners, guides, and chain because a worn guide can cause play in the chain causing chain splapp at times. When i had a noise like this and read a article that it was the chain causing a noise like that, the chain would be wore out where it meet the gear causing play which cause a ticking noise. Unforuntaly, long story short my problem was the cam bolt lost its TQ and allowing the sprocket to backed off and the noise I was hear was the cam sprocket whobble back and forth on the cam shaft until it broke.
