Cold Start Noise Help

[Graybigh20]

Hi,

I just recently bought a 2020 Ram 1500 Big Horn 5.7 V8. The dealership I bought it from said the cold start noise is normal to this engine and vehicle and not for concern. The noise is only there on cold start and lasts for about 15 seconds or so. Can someone please listen to this video and let me know if this is indeed normal or a concern I need to have fixed asap? See link below.

Thank you for the help.

Kinda sounds like an exhaust manifold leak. Very known problem. Heats up noise disappears. My 20 Laramie longhorn is noisy on startup even after they replaced the engine.

That sounds like the exhaust manifold bolts if it goes away after it warms up or gets more quite I would have them fix it , it wont hurt anything just annoying, you can run it in to another dealer.

I had a similar noise. Took it to the dealer and they found both exhaust manifolds were cracked (39,000 miles). Luckily cover under warranty. Dealer said this is a known issue, although not usual at such low mileage, caused by the continued heat/cool expansion/contraction which cracks the cheap metal used for the manifolds. Of course they advised after completing the work of replacing OEM with OEM that, unless I put in after-market aluminum manifolds, it will occur again.
