Default I guess it wouldn't be a ZR-1 without an oil leak.

Parked inside since the weekend, and I took a look at her today. Found a nice puddle under the front of the engine. It already has Jerrys oil cooler lines, so I doubt it is that. Was pretty dark too, so I'll have to check again in the AM.

Only thing I can imagine is engine oil, or PS fluid?

Check oil pump access cover and cam sensor seal. I had both happening at the same time.

Will do.
Are they easily repairable, or is it a special part required, otherwise known as another Jerrys order?

On the oil filter housing facing forward low an hidden - oil temp sensor
On top of oil filter housing - oil pressure sensor
Right side of filter housing facing down - low oil pressure warning sensor
Under and behind low oil pressure sensor - cam chain tensioner port
Above oil pan - crankshaft sensor
Under the crankshaft sensor, on the oil pan - low oil level sensor

Of course, oil pan gasket can be a source of oil leak also.

Oil leak can be any of above or combination of above locations.

Iirc, we did all the sensors. So I'm guessing that narrows it down some. Plus, previous owner had the oil pan dealt with. So that should make the options just a few.....

We will see next week when she is in the air.

You can immediately eliminate all the ones that are easy to get to.
