Hi all! Link for audio of the issue:
Over the last couple days my truck has been doing this knocking rattling sound on cold starts. The engine will fire up and run quietly for about 15 seconds, then start making the noise in the video for about 30 seconds to a minute, then go back to running normally. It is only on cold starts after the truck has been sitting for a couple hours.
Every now and then, I'll get a bit of a tick on cold starts from what I assume is the lifters building oil pressure. This is not the same sound.
Granted this is my first gasoline Ram, but my gearhead brain is telling me this isn't normal. Yet, oil pressures are what they've always been. Never gone beyond 4000 miles before changing with PuP oil and WIX filters. Bought it brand new about 10 months ago and have a little over 15k miles now. I do plan on going to the dealer soon since it's still under warranty, I'm more worried about how long this repair could potentially be.
I thought maybe it could be a loose or broken exhaust manifold, but I've never heard one sound so "mechanical" like this one is, and from what I can tell on visual inspection everything looks fine. No rust, nothing loose, etc.
This below thread on Ram Forum has me worried I might be needing a new motor. The possibility of having this truck down for as long as some people have said, makes me a bit nervous.
Anyone have any input?
