Chasing a Knock/Tick Ok So i have been chasing this Knock/Tick for a while now... I thought it was a bad/collapsed lifter.. Got a set of stockers from a friend that had 30,000 miles on them.. Soaked and installed..Same noise still there... On Cold Startup there is no noise... Once the Motor starts getting warmed up you can start to hear it..Once you hit about 200 its there.. not at idle only if i put a good load on the motor or rev it up a few times.. Its louder after you give it gas and while the RPM's are falling you gas it agian.. Not really present above 3500 rpms only under light to moderate throttle or while cruising at a sustained speed.. Then once it starts to knock you can go back to idle and it will knock for a min or 2 then quite down and disappear until you bring the rpms back up... I checked the Rockers (looked good) Pushrods (looked straight) and the the lifters were changed... I have 45-50 psi on cold start up 30ish on hot idle...PSI does raise with RPM increase... I have heard about the O-ring .. But is there anyway a Stock one could just up and Cut or Tear itself... Im stumped here..i dont see how it could be a bearing as it is not there all the time only under certain circumstances... Oh and there is No loss of power or drivablity...I have put well over 5-600 miles on it like this.. I figure and Bearing would have thrown or got louder by now....

Yea..Ive heard a motor with a bad rod bearing it was loud as hell and only got louder with RPM increase and was there all the time... And a wrist pin... I almost was thinking that ... but i had a truck that had a bad wrist pin once and it got really loud in the upper RPMS or the more load you put on the motor ..Mine dissapears the more gas you give it...

What about Timing Chain?!? Someone suggested that. Like maybe it has slack and its slapping something.... But i didnt think it was possible.. But i guess with the LS1 Anything is Possible!... I really hope its not a Bearing.
