Strange engine noise

[Luso-Merc]

Hi folks!

I bought a 2003 a while back and have been getting it ready to hit the road this Summer. This one has about 60k miles on it and sat for a few years, as far as I know.

It's pretty much ready, however it's emitting this slight clanking noise from seemingly the bottom end of the engine. It only starts after a few minutes of running, I imagine because the engine oil has warmed up a little and gotten thinner.

I fear it may be related to crankshaft bearing wear, but this car doesn't look like it was beat on at all. I never worked on an issue like this before, so if someone could provide some insights before I have to take it to a shop, it would be very much appreciated. Video of noise in the Google Drive link below (I think it's too big to upload here).

Thank you for your time!

PS: Sorry if I posted the wrong way, this is my first time starting a thread here.

Pretty commonly reported, do you have Facebook? My Marauder makes the same noise, along with others.

There's more on the comments sections of those posts and on youtube.

Does it go away when the car warms up? Check the manifolds for leaks if it goes away after it warms up. Could also be related to, as I was once told to me, connecting rod slap. Do you have an engine stethoscope? Could help you narrow down where the noise is coming from.

Mine has a similar noise (112k miles). On a cold start is fine. But when I drive it and leave it off for about an hour. The cliclk clack starts and goes away in about a minute.
