But that doesn't make sense really?
The seal is higher than the oillevel, so how could it leak from there when put on the stand?
I did replace that seal though the other day: the 'open' side towards the primary and the 'closed' side towards the transmission.
This was the way the old one was fitted and the only way it really made sense to me BUT I'm sort of doubting now, as it said 'oilside' on the closed side...which didn't make sense...

I've always found that if a problem springs up shortly after you have wrenched on something it's always a good first place to check.....

It's NOT transoil: I can tell by the type of oil and by the fact I have changed the mainshaft and shiftrod seals only last week 
So either it's the derbycover doing a number on me OR the mainshaft primary side, which would be just bloody typical...as it all has to come again!

THE PLOT THICKENS!!!
Just to be sure, I've swapped the derby cover gasket and went for a ride.
Came back just now and parked it on the stand and hey ho, instantly it starts to leak so it's NOT the derby cover.
And now for the plot twist:
The oil is...COLD!!! It's starts dripping cold oil...and it seems to be motor oil as it's greyish in color if you get what I mean...
So where the bleedin' hell is it coming from?!
The oilplug is completely dry...
I'm stumped...

Deffo no gearlube!!!
Different smell, color and viscosity...
Will take sample tomorrow and go to bed annoyed today...
Last week I fitted a 96"S&S because I had a transleak...so I'm a little annoyed that I have a different leak altogether now...especially since I don't have a 124" to remedy it...

Oh crap...I might have just figured out where the leak might come from...
It's an FLHTCU so it has an oilpan...now that looks completely dry on the exhaust side of things but that doesn't mean it won't leak when the oil's hot and it's parked up...
So will re-torque all the bolts today and if it still leaks I guess it's time to replace the gasket and see if that cures my mystery-leak...

Quite obviously there are only three places the oil can come from, it's just a matter of identifying the culprit. I wouldn't be fooled by the oil seeming to be 'cold', as that ain't possible after a decent run! Bear in mind that it can travel to places nothing else can get to and it is a challenge to find where it is getting out. Oil under the chaincase can easily get there from both trans and the chaincase, via the seals between the chaincase and trans.
