So when I park, I notice theres a drop or two of oil on the floor below the right (passenger) side header. Where could this be coming from? I have a LT1 Z28.

 

valve cover, intake manifold, rear main seal, oil pressure sensor, oil pan, to name a few

 

damn....lol thats alot.

 

it's relatively easy to find an oil leak.
with the engine cool start from the top feeling around the bottoms of the valve covers on the cylinder heads and the back of the intake manifold. If those areas are dry then look at the oil pan and see if there is any seepage.
If you feel any kind of oil around the areas mentioned then there is definitely a leak.

 

Think it's coming from the power steering fluid resevoir. Cleaned the bottom of the car out and couldn't find anything, then I noticed a trail of oily stuff on the inside of the right tire well. Are resevoirs expensive and is my theory anywhere near correct?
