'05 ram scraping noise

[mlabuda]

2005 ram 2500, 5.7 makes a kind of metal on metal scraping sound , almost like a water pump getting ready to fail. Seems like it lessens as it warms up. Removed the belt and it still makes the noise so I can rule out anything driven by the belt. My worst fear is timing chain and tensioners. Any other ideas? Thanks.

If you’re sure it’s from the engine not the transmission I’d probably drop the oil and install a new filter and fresh oil and see if there’s any change.

You have checked oil, right?

post a vid of the noise should be able to give you a good idea from that timing chains are not to common to fail on 5.7 does happen tho the tensioner somtimes fails.

Ok here is a video with sound. Fresh oil and filter, no change. Sounds the same with the serpentine belt removed so its not any thing driven by belt. I am suspecting timing chain tensioner. I dread tearing into it though. Screw it. I am a computer idiot. cant get video to work.

Do/Did you have shiny sparkles in the oil when you changed it?

Oil was free of shiny metallics, even cut open the filter, looked OK. I have a recording of the sound but can not get it to download. Screw it. Cracking it open this weekend.
