A friend brought his car over for me to help him get it running better (points were very rough and even loose). Once we got it running nicely we left it running for a while. Then I noticed a huge oil spill under the car - more than a foot diameter after 10 minutes running.
Take a look at this video. Oil is pouring out of side of bell housing.
After shutting it down, I checked the oil, and it was even a tad overfull. When I inquired, my friend said he had changed the oil a couple weeks earlier. I suspect he may have put to much oil in it and it is just puking out the extra.
Or, did his rear main seal suddenly disintegrate (engine was last rebuilt 50 years ago).
Appreciate any thoughts you might have.
Hope this youtube link works and you can see the oil pouring out.
