Hopefully it is
Do you think I need to run longer p-rods? Im not sure of the base circle on my cam but everyone else said I wouldnt need them. The cam is the LS1 Hot cam. Cause if it has a smaller base circle I would need longer ones or else it would cause a lifter to fail?

Mine and yours have the same base circle... I used 7.4 hi-tech (hardened) push rods from comp... but they are stock length. Go do this. Get an oil change and put a bottle of rislone in it at oil change. Should make the ticking go away if its a lifter. If its an exhaust leak, you should be able to crawl under the truck while its running and hear it. If you do a cold start up, you might be able to spray a little soapy water on a suspected leak point, and get big bubbles. But this wont work on the headers, because they get too hot too fast. I remember I had to tighten my header bolts a few times because of a slight leak. But for gods sake don't break a bolt lol.
I believe its a sticky lifter. Probably has some trash in the oil. Rislone should fix you up.
I was thinking the same thing. Ive never used Rislone but hopefully it will solve my problem! So I basically pour it in and let it idle for a little bit and check the results? Do I need to get an oil change directly after? Wierd thing is I got an oil change like a week or so ago with castrol syntec and thought that would help out but it didnt. Ill check for exhaust leaks tonight while its cold and do the rislone before I take it to the dealer in the morning. Thanks so much Jeff for the advice!
Do the newer engines though have LS7 Lifters? Its a rumor that has been in my mind lately

read the instructions on the bottle of Rislone. I believe it says to not drive the vehicle while the product is in the engine. The Rislone is a thinning agent to wash away the built up gunk in the engine. Again, read the instructions before driving the truck with the Rislone in the engine.

You can put it in whenever you want... It works best IMO if you change the oil first... then put it in. I have had many noisy lifters quieted with this stuff in the past. Works on any motor with sticky lifters. A lot of mechanic shops use it too. It really works.
