I have had my 1952 6T/Thunderbird for over 40 years. The crankshaft broke when the primary chain broke. My local shop replaced the crank but I am left with crankcase oil transferring into my primary chain case. The engines cases are 1951 manufacture. The crank is a newer 3-piece one and the drive sprocket has a 23 teeth and has what looks like a seal surface that is 1.31 inches in diameter. With the crankshaft and the sprocket this is a typical bastardized assembly I have used since 1977.
Yesterday, after removing, checking, and reassembling all external oil and breather lines I put 40 miles on it and had 1/4 inch more oil in my primary.

Anybody have a problem like this and solved it? Am I supposed to have a seal, large diameter thin flat washer, or felt washer to prevent or lessen oil transfer into the primary?

I am newby enough to not see how to post photos with this post

I use imgur.
In imgur I use:
I click on the photo I want to use
Select 'Direct Link' and click on 'Copy'
Set the size ...this one is 'Large Thumbnail'

In Britbike I use:
Full Editor
Then the icon next to the smiley face and before the clapboard....'Insert Image Link'
and use Control V to paste my link in.
Then hit 'OK'

I'm preparing to take it out for a hundred mile spin to Valley Center and back. I will post the changes.

Bill thanks for posting the photo. That was at the Hanson Dam Run last year.

I joined this forum and a premium ($25) member and as of now don't see any Attachment Manager. I didn't spend the $100 plus for the 5 year membership.

Concerning the headlamp, in 1972 I traded a gram of has for it. I was told it was from a 1910-1920 fire engine spot light, by Vesco, made in Chicago. Now people tell me it's "Steam Punk." When I put it on I don't think the term existed. No parts were harmed. I've never had the proper nacelle. Not sure what you meant by "shade?"

The bags say ERII Royal Mail. I had them screened, along with a few t-shirts.
