[Flathead Fever]

You need to go on the Pasadena Roadster Reliability Run. After all those flathead powered roadsters leave the parking lot it makes the recent Gulf Coast oil drilling disaster look insignificant in comparison.

Obviously, if your flathead wasn't leaking before and its leaking now it not because its a flathead, there is something wrong. Its' going to leak a little out the rear main seal but not as bad as your describing. Did you ever notice the cotter pin from the factory that is installed in a hole at the rear of the oil pan below the clutch bell housing. My guess is that it was designed to keep the hole from plugging up so your clutch bell housing would not fill up with oil. A little seepage was normal back when they were making gaskets out of rope and tree bark.

You could try having British Petroleum lower a tube down to the rear main seal and pack the hole with mud and concrete.
