Oil pours out of ventilator tube

[Bill Davis]

You didn't add more than five quarts of oil ?  Is the crankcase over filled ?

In the 36-42 master parts list the tube is referred to as the "tube assembly" in Plate 10-1 on page 183 - don't know if that is also called the road draft tube. I have not checked any of the engine intervals yet because I did not know where to start. Thanks for the suggestion.

Out of the road draft tube?

Is there any blockage on the holes that allow oil to drain from the valve spring gallery back into the pan?

I own a 39 Plymouth with the original numbers matching engine. The engine was rebuilt by the previous owner and never ran. I have the engine running but have a problem I have never encountered before. The engine runs well, doesn't overheat. But once it has been running for awhile and the engine temp goes over 160 the oil begins to pour, not drip, out of the crankcase ventilator tube - whether at idle or after a brief drive. What could cause such a problem?
