When having my 37 115 flatbedded to my new home up a very steep driveway it leaked a huge amount of oil out of the weep hole in the bellhousing. Never leaked from the rear main when driven in and out of old garage or for a few miles locally. Can the rear main seal suddenly go bad (this is a "rebuilt" motor with only about 10 miles on it). Or is there another way engine oil can get into the bellhousing?
I'm worried that the clutch will get oil saturated too! Brad

Are you sure your engine has a real seal?

Just by memory I thought they used a slinger (a quite common practice of the era) and if so, slingers only function when the crankshaft is rotating so with the engine off and the engine at a severe nose-up position, I would expect oil to pass and come out the clutch cover weep hole. I have experienced the same thing when having my '34 which also just has a slinger loaded onto a flatbed. Assuming your weep hole is open and the oil drains, I wouldn't be the least bit concerned about getting oil on the clutch.

If I'm wrong and your engine does use a real seal, I know someone will come along and correct me.

Thanks, Mr Ambassador; now I feel real dumb! I am more familiar with newer engines, so I never thought about the possible lack of a seal! A real load off my mind, although it looks like I may not be able to drive the car up my driveway without loosing oil.....

It could come the rear of the pan. G

No oil seal

On my 34 8 cylinder oil also leaks from the rear main is there any way to fix it with pulling the engine. the enginge only has 7600 since it was rebuild as fas as I know.

As noted earlier, your engine (and many engine designs of that era) uses a slinger rather than a rear oil seal. Unless someone has butchered the slinger or plugged the weep hole, it's almost impossible in normal use to have any significant oil loss past the rear bearing unless the crankcase is grossly overfilled. Take a closer look, far more likely it is oil leaking from somewhere forward and running rearward.
