I've recently noticed a metallic grinding smell when I back my car out of my driveway, it smells just like using an angle grinder on steel. This would seem to indicate that there is some metal-on-metal grinding, presumably in the clutch since it's only present when I back it out of my driveway (it's uphill and I have to slip the clutch most of the way out). The PO indicated that the clutch was replaced in 2017, likely less than 20k miles ago. I'm pretty easy on the clutch because I know how expensive they are, I'd be surprised if I wore it out in that timeframe.
The only thing I can think of that would cause this is maybe one of the flywheel bolts backed out, looking at the service manual it doesn't look like any other bolts could back out and cause this. There is some clutch shudder when it's cold out, but I chalked that up to being a normal NSX thing. Anybody have any other ideas? I plan on getting it up on jack stands to take a look, anything in particular you'd look for?
