So, I now have an issue and I can't quite pinpoint it. The sounds is almost like clatter/grind, it is quite loud at low speeds - but, it only manifests when 1) the transmission is engaged and 2) I am on the gas.
It gets more pitchy as the throttle gets more open, but if I press the clutch pedal in, it disappears. If the car is sitting idling in neutral, the sounds is *still there*, but softer. I put her on the lift and used the mechanics stethoscope to listen for things in the engine bay and underneath while it was running with cruise control engaged.
The sound is loudest (can be heard without the stethoscope, really) at the transmission end (driver side). Everything else underneath is relatively quiet. But, in the engine bay, the stethoscope picks it up the loudest at the "fuel rail" (the thing that can be seen in the picture).
I am inserting the link to the sound file as well (this one I recorded IN the cabin, while driving - so, hopefully it can be heard even with the road noise and other noises that the intake and the BOV make)
Sound file.
Could really use the "swarm knowledge". People talk about DI chatter, but this is way beyond this, and, as I note, it is quite apparent at the transmission case.
