Background: 907xx miles, manual, no prior engine issues.
Went to head to campus a little while ago and the Box won't start, just cranks (no odd noises). Hmm, try again. And again. Then I noticed that the oil level gauge kept dropping each time I had tried to start (and thus stopped).
I checked the dipstick and it doesn't seem to be out the the ordinary, however there seems to be (per my uneducated observation) oil in the bottom of the coolant reservoir.
It's not intermix, but definitely separated with the clean coolant on top.
I last had the car out on Saturday and it was driving beautifully. Not turning much up with the Bentley and I'm about to hook it up to the Durametric.
Could this be a bad oil cooler? The garage floor is dry, no drips of any sort.
Update: Replaced sending unit (w/ internal fuel filter) and fuel pump with used examples, drained the gas tank completely, and refilled with fresh 93 octane. Problem solved. Old fuel in the tank smelled old, not as pungent as fresh gas does - likely a contributor to the failure.
