Jeep 3.8L V6 Ticking noise

[stainlesself]

Hello all hopefully you can assist me with an issue. I recently replaced my cylinder heads on my 2011 jku. After everything was sealed up and after starting the Jeep I noticed a ticking noise when running. The noise is from the driver side bank and all of the lifters look fine when I inspect them while pulling the heads. Furthermore, the ticking noise seems to stay at the same noise level even at temperature and ticks faster when RPMs are increased.
Any idea of what it could possibly be? Any and all help is appreciated!

Thank you!

lifters may look fine, but did you check the rocker arms and cams for wear?

Just got done having mine repaired, rocker sticking and it ran for several years with the tick until it didn't; replaced all rockers, lifters and cams, the cams were worn down like an abused pencil erasure lol

initially I thought maybe exhaust leak because it was random and only under certain conditions, then I started getting the engine light and misfire at higher rpms.

EDIT:
Just noticed it's the 3.8L - my comments are for the 3.6L.

Check the manifold per @WJCO, I've replaced the driver side manifold on my 2010 JKU at least 4 times since 2010.

start it when cold and spray the area with soapy water.

Sure it's not exhaust manifold Crack? Common

Replaced the manifolds as well with the heads I am thinking maybe a loose bolt

you can also hook up a shop vac to the exhaust and run it in reverse, no need to start and heat the manifolds, use soapy water in a spray bottle to locate the leak(s)

Might have to do this and see what the results are.

Def check the manifolds. I had a set of manifolds I installed and the passenger side was already cracked. Had to replace the replacement
