So, there's oil (or something) leaking "into" the car from outside: under the driver's seat. My feat, while driving, are being moistened in my now-oily carpeting. Anybody know what's faultering here? And what needs to be fixed/replaced/done? Anybody ever had this problem?

I'd be grateful for any help/illumination,
thanks,

Anything to indicate what kind of oil it is? A tell-tale odor, for example?

Frankly, unless it's really coolant (which can have an "oily" feel from the antifreeze component -- but it smells "sweet"), I can't think of anything that normally* contains oil that should be in the passenger compartment.

[* something not usual: any chance that you have a mechanical oil pressure gauge? These old things (in contrast to an electrical gauge with a sender in the block that's 'wired' to the gauge) would have a small tube that runs from the block to the gauge -- the tube contained oil under pressure, to drive the gauge's mechanism. Old Mercedes-Benz cars that had this kind of mechanical gauge sometimes would dump oil on the driver's carpet when this tube leaked at the gauge's fitting.]

Otherwise, you've got me stumped.
