    I may have one thats a stumper. I think its a lifter thats intermittent. It is like a 'tap' now & then on the right side, the cam cover. (98 EVO) I checked the compensator clutch, had the cam cover off & inspected for debris, & also has the push rods exposed & when centred all have the same tension as you can wiggle them all the same. Noise happens 1-5 times a minute.
    Oil presure is fine (20 or so when under throttle)
    This noise only happens now & then, cant just make it happen, but it is always under light throttle or decel, or even idle. Loud light (Not deep) clunk or sounds like a bolt or something moving around in the cam cover case & hitting it. But, theres nothing in there loose.
    Any suggestions would be apreciated, otherwise I will continue to ride it & see if it gets worse. Searched all around here & the internet, cant get a targeted senario. :witsend:
