Marbles in a can noise comming from engine bay

[Juan Alvarez]

Checked all of that and it’s clear. No oil leaks and everything is good condition considering the year of the truck.

The ball is in your hand now, what you do next is entirely up to you...

I have been doing some more digging and I found that the noise sounds like it may be coming from closer to the firewall and it’s definitely not a rattle or a slap.

I honestly hope you're not true about that thought, cause if you are I'd much rather start looking for a new motor if I was you.... theres nothing back there but valves and pistons

 

[Habbibie]

You know what, why dont you go to autozone and rent the piston compression tool, then test all 8 cylinders and report back your findings.

 

[Juan Alvarez]

Hadn’t that of that at all....will do tomorrow

Better to know if you have a dead cylinder now before digging into the timing cover.

I finally figured out what the problem is...I have a bad flex plate. If you have time and youre interested, youtube the following video: Diagnose knocking noise-cracked flex plate. This is the exact same sound my truck is making. I knew I had to replace the torque converter but I knew it wasn't the torque converter making that noise. I at least can rest easy knowing I don't have to replace the timing chain for now. Either way, I want to thank everyone for the advice and suggestions.

Good deal. That's much easier and cheaper to do. Let's us know how it turns out. You thought the noise was coming from the front? Glad you narrowed it down. Flex plates crack, and cause a god awful racket. Pull your tranny back, should be an obvious crack on the plate.

FTI, my 8yr old serpentine belt, made a chirp noise, when damp/rain/car wash.
