    This was the best post ever, I had been saying that same exact thing for a decade but never had the proof, just a theory. This also makes total sense why redline is helping hemi tick. The tick is perpendicular force in the cavity, been my thoughts on this since I first got the tick. This is why extreme pressure additives can help this issue, and also why they take time to kill the tick, this is the exact science of it posted many times. I hope you dont mind, gonna poach this vid for syn thread.

    Thanks man for posting, real helpful post.

    Has to be high molybdenum, read moly basics if you haven't. Thanks to you the final piece of the puzzle has been brought to ram forum. I feel like my work is DONE.

    Perpendicular force also explains rollers that get damaged, I been saying that ad naseum but guys kept saying needle bearing this needle bearing that. Think about it, if that roller hits the lifters but the lifter has perpendicular force pushing down on the roller, I don't care what bearing you have you are going to cut the cam lob.

    The best part of your find is that it suggests that if you kill the tick, you likely smooth the perpendicular force, and that this fixes the issue instead of just masking it. No more cut lob, no force on that roller. Best day I had at ram forum, all the thanks goes to you, and well your uncle as well:)

    I keep hearing when I first got a Hemi was the Hemi tick. Hemi tick this Hemi tick that.
    So idle and low rpm is no good for Hemi. Get 5w-30 weight oil rather then 5w-20. Anything else?

    And now I'm ordering more RL, the heck with the extra cost.

    Granted my truck hasn't really moved in 3 months other than the occasional grocery or Costco run. Thanks a lot Chinuh.

    Wow. Wonder why no one else has shown this. Sounds pretty straight forward to me. Where are the other engine builders pointing this out? This is a huge deal. To us consumers, to fca.

    I try to keep my engine tached up, as I feel it runs better. F gas mileage. Let her eat and hope for the best.

    Does the 6.4 have the same flaw?
