Owner reported: Hey everyone,

My 2018 Ram 1500 Laramie with the 5.7L Hemi has developed a ticking noise, especially noticeable on cold starts. It seems to get a bit quieter once warmed up but never fully goes away. I'm worried it's the dreaded Hemi tick.

I've read a lot about it possibly being exhaust manifold bolts or lifters. The truck has about 85,000 miles on it. Has anyone experienced this with their 2018 …
