I recently bought a 38 Pontiac 6cyl with all original parts, still runs fine, except one question. I plan on redoing the whole car, but for now I'd like to have it running how it is. There's about a 2" pipe that comes out of the engine block right below the exhaust manifold, and goes straight down and is open....when the car is running it's fine, but as soon as I start to give it gas, oil, a whole lot of oil comes flowing out. What's the deal with this pipe? thanks.

I think you are referring to the crankcase vent pipe. Before the EPA got involved, all cars vented their crankcase fumes right out into the air. Then PCV came along, and now we feed the fumes back into the engine to be burned in the cylinders (much more environmentally friendly)
If you are pumping oil out of this, the rings are probably shot, or some part of the baffling system is not there or working properly.
Could be something else, but that is one thought.

hmmm. Memory test.... I think they were called a road draft tube????
"or some part of the baffling system is not there"
That was my first thought...
