Hello all. My rebuilt 5.9l with around 4k miles has a small tick at idle. I put on hearers a week ago and it DEFINITELY has a leak somewhere, but I'm not sure if this sounds like an exhaust leak or valve noise at idle. It has a comp cam and the valvetrain has always been a touch noisy but I'm just looking for opinions on this. It's very faint and probably nothing but opinions never hurt right? If u listen in this video very close you can hear it. One thing I've wanted to do since running this motor is pull the valve cover and make sure nothing is loose. It's always had a tiny bit of a tick.

If you turn your volume up a good bit you can hear the noise.

 

Fix the exhaust leak, see what's left. The dead soft aluminum or copper gaskets work the best.
