I just pulled the flywheel off my 1921 Peugeot 161 engine and discovered that it has no rear seal for the crankshaft. Instead, it is a "close fit" with a screw thread cut into the end of the shaft which (I hope) draws the oil back into the engine. Is this a common feature on cars of this vintage?

I have seen this on crank and transmission shafts,,on both cars and motorcycle,,Vincent used this on crankshaft to keep engine oil separated from chaincase,, I'd have to think on the cars,,but I have seen it and they seem to work as long as the bearing is not worn out,,OR,,too much backpressure in crankcase,,Hope this helps,,,Ben

Very common on pre 1930's vehicles. Oil will run out if you have the car on a steep enough slope, like loading it into a trailer with short ramps

1948 Buick Woody
1931 Model A Tudor

It also has a weep hole on the bottom. I suppose this directs the oil down to the ground rather than flinging off the flywheel.
