I have a 1948 S11 Custom with a flathead six and fluid drive. I have oil in my radiator. I just recently drained radiator and back flushed. The car sat over night and I checked the radiator again. OIL in it. My mechanic is puzzled. He has seen water in t 
he oil but not oil in the water. Anyone have any suggestions on where to look?

I would think in the old cars you don't have a pressurized
Radiator you have more pressure on the oil side rather then
the water side 
Was this a running driving car? Or is it just getting back on the road?? What does the oil pressure read when it is running? Can you post a picture of the distributor side of the engine?
I have some ideas but they are so whacky I don't want to say until I have some evidence.
Have a nice day

Hi Steve,
Thanks for responding.
The car is running fine. I drive it around town frequently. Recently replaced water pump and had radiator recored (big bucks). After driving around a short time after replacing said items checked the radiator and that is when I found the oil.
Hope the pictures made it alright.

Hmmm. I would suspect something with the water pump installation. Maybe one of the mounting bolts is open ended into an oil gallery and not sealed up. I don't have an engine sitting here to look at. Maybe someone else does?
Good Luck
Steve
Does anyone think this oil maybe coming from the Fluid Drive transmission?

Not likely as the fluid drive is a sealed unit. It does not share fluids with other drive components or the motor.
