It has a 20% failure to get the tick rate, consider yourself in that category. I also included a video in the Syn thread as another source of tick not lifter or exhaust bolt related, that no oil can prevent. Interesting watch, pay attention to the second example he had. We know your engine was ****** at birth, it sucks ass but if I was you I might bite the bullet and trade it in before warranty is out in oct. Or go back to PUP and make that tick louder and fight with the dealership. That is a real problem with running redline, it may quiet something you want to get warranty work on, lol. Also, it is a very mild tick, it is possible that truck with last, but I do believe it is a higher risk engine with the histology. I wouldn't F with additives at this point neither, you already got the good stuff there, but that is your call.
As always, thanks for the honest update.
