I am trying to figure out what would be considered "normal noise"?
Mine is quiet as a mouse with the windows closed- just a bit of growl when I get on it. But when I roll my windows down, I can definitely hear what I can only describe as a faint pinging- and it echoes off the vehicles around me, almost like a tiny exhaust leak- but they have looked twice now and can't find an exhaust leak and keep telling me it's normal sound for the 6.4L. Startup noise is none existent- it's sounds the same as my 5.7. It's just when I get on it.
I dunno. Maybe I am worried about nothing. I was kind of hoping to set a baseline for what would be considered "normal" under load or acceleration. Maybe @Tach_tech could lend a little advise? Are the 6.4L just a naturally noisy engine?
