So I have a rattle that I've been trying to pinpoint for some time. It sounds kind of like gravel been ground up or something it's a very weird noise. Kinda diesely, it's hard to explain. If I am around 2-3k it'll be prominent with very light load (10-20% throttle). Won't do it with no load and won't do it if I'm accelerating at a normal rate. Won't do it if I'm going pedal to the metal. It will do it when I shift up at around 2-3k every gear, every time.
I was in neutral just revving it and getting it to make the noise while I played around with a stethoscope and it seems to be most prominent when I'm on top of the driver side valve cover near #6 cylinder.
It's a 98 4.0 ohv so no I don't think it's the chain at all.
I read on the explorer forum the guy seemed to have the same issue with his 92 but never found an answer to the issue. My friends 97 4.0 ohv also does it when it shifts sometimes, not as frequent as mine though not as loud either. His is auto however I got a manual so maybe it's easier for me to make the sound since I can control the shift point.
