Mysterious Ticking in My '19 Ram 5.7

[100calories]

I've got a weird ticking noise coming from my '19 5.7 4x4 that's driving me nuts. It's faint but noticeable when you're near the truck. Doesn't change with rpm or engine temp, and I can't seem to pinpoint it with a stethoscope. No codes or other issues. Changed the oil and filter regularly with good stuff. Any ideas?

Do you have a video of it? It's hard to judge without hearing it.

If the ticking stops after the engine warms up, it's likely a cracked exhaust manifold bolt. This is a common issue, often called 'Hemi Tick.' Every Ram I've owned except one has had it. My 2011 cracked around 80,000 miles, and my 2019 cracked at 30,000 miles. They supposedly improved the bolts in the Gen 5s, but now the whole manifold tends to crack instead.

I'm guessing it's the manifold. It could be damaged. Try to pull the heat shields to check.

I'm pretty sure it's the manifolds, had that issue on my old Pontiac before, turned out the manifold was cracked
