well oil looks ok so i'm guessing the bottom end bearings are ok. running over to a buddies shop to see if he can get a stethescope on it.
Just leave it with Matt. Built motor time!

From inside the cab it sounds more like a tapping. If its the valvetrain I know exactly when I did it too lol

Sounds like a chirping lifter. That's what the other lifter vids sound like anyways.
Soo when did you do it? Sounds like a good story.

thats probably the only time that truck has been over 2000 rpms lol
Lmao! True, that's why he knows when he did it.

Does it even have enough power to break itself?

Steroids don't mix well with diesel fuel

There's always more to the story.......
Day 1: "I have no idea what's going on, it just happened......"
Few days later: "Well you see, funny thing is......." LOL
Lack of leg days, results in a throttle he can't control.
I thought it was because of those fag shoes he wears. Although not quite as gay as Gare's crocs.......just sayin.

i leave you fudgepackers alone for a few hours and look what happens......
anyways, just spent a bit over at Mad Matt's in Fort Worth trying to see if we could pinpoint the source of the noise without tearing it apart. the whole way over there is was pinging pretty loudly. decently loud in cab and when i rolled down the pass window, I could hear it quite well.
Gpt to Matt's and he immediately heard it on the pass side. my first thought was lifter/push rod but there was no popping at all. just the same RPM dependant tick/squeak. We started with an electronic stethoscope and poked around in several places. it seemed the loudest right on/behind the GPR bracket on the pass side. we took the filler cap off and stuck the scope down in there but oddly enough, it didn't seem to get any louder.
We then popped it on the ids to run a power balance and everything checked out perfect. turned off injectors one by one and no indicators. messed with ICP and IPR to see if there was anything funky with an injector and still no indicators. Compression was near perfect in every hole so no apparent rod or piston issues. i know this is all electronic and not mechanical but nothing is jumping out at this point.
turned the truck off and went inside to bullsh*t for about an hour. went to leave and started it up and the noise was significantly quieter...almost non existent. oil temp was around 110 degrees. got a tad louder as the truck warmed up but the entire 30 min drive home, the noise had seemed to quiet down a lot. mind you the whole way there is was pinging away. got home and you can barely hear it with hood up.
any ideas now? could it possibly be tune/oil related? i'm wondering if it's a hydraulic noise and the cooler oil temp changed something. the tune i'm currently running is only about 2 weeks old and I only drove it for about a week with it...

One of our trucks had bent a rod and made a sound like that until it grinded down enough to stop making the noise
