Gentlemen, I need your help diagnosing this noise. Has been happening for awhile ever since I got the truck back from having a new head put on. Don’t remember it making the noise before. I’m thinking either detonation or misaligned camshaft? Here’s a video of it. It’s a rattling noise at higher RPMs when I’m about to shift. In the video I start in first, then hold second so you can hear the noise, then shift to third.

 

Need a vid of the engine bay, idle and some light revs. Can be a lot of stuff. You also have a exhaust tick somewhere.
"could" be: chain tensioner, misadjusted valves, too tight rocker cover (easy to overtighten, lifters will make contact)

Or ... it is the unsolvable noise here: https://www.yotatech.com/forums/f116...-knock-306237/
Joking. Everything is solvable.

 

 

Take the valve / rocker cover off and look at the inside of the cover.

Do you see any indication that the rocker arms are contacting the rocker cover?

 

 

 

Get a dowel rod about three foot long, put your ear on one end and start holding the other end on different locations on the engine, valve cover, etc till you find exactly where the tick is... then report back

 

Figured I'd update this since we figured it out. We finally had some free time to tear apart the front end, staring with the timing chain cover. Found a bolt on the cover was too long (not original) and was coming in contact with the timing chain. Thankfully there was very minimal damage as I barely drove the truck after it started making noise. Apparently the guy who worked on the truck at the shop I took it to had no idea what he was doing since he lost a bolt and put a wrong size one on. He also didn't put a new gasket on, which was the source of my oil leak. $12 gasket and a bolt I had laying around fixed all of my issues.

I swear...

 

Mechanics get a bad reputation overall because of things like this, which is frustrating.

I am glad the noise was something simple though!

Thanks for posting an update.

 

Welp, turns out that did NOT fix the noise. Instead, I need a new engine. Pistons and rings are shot and it's not worth rebuilding. V8 time.
