be careful with those,they can round the edges of the cases--------I use a gasket remover spray and a good gasket scraper taking care not to shave metal off the cases.This subject can be debated all day.If you must use a drill or air spinner use the 3m brushes that look like a dog grooming brush(I cant remebr what they call them ) maybe the name is rololock?the scotch brits can move enough metal it sometimes isnt very friendly
Looks to me like the oil return from the heads has been plugged, your engine has had some work done on it before.
Some people and manufactures of heads do this in an effort to reduce oil temperature, (If you have the manual and look at the fold out insert of the oil system illustration 2 figure 10). The return is plugged and run outside the case in an effort to reduce oil temp. If you do not have external lines I would think it would have been puking oil. Could there be a chance this is where the motor was seeping from. Others with more experience on this should be able to help shed a little more light.

I agree that she's had engine work before based on the metal gaskets I found.
Funny thing about this hole is, the little round piece was in it when I lifted the gasket that was over it. The hole goes into the engine case, but there's nothing else attached to it.
And yes, the seeping was on this side of the motor on both jugs.
I wonder it there would be a way to plug it (short of welding) that would be a more pemanent solution.
From what I have been reading, you are saying there was also a base gasket that covered this plug. Hard to tell in you pictures but is this the drain for this hole in the head in my attachment or does that hook up to your copper pipes you mentioned above? Is there a hole up thru cylinder that lines up with it? Could you base gasket leak be caused by the column of oil remaining in the cylinder?

Good question. I know the copper tubes are both on the other side, but I can't verify if there are holes in the jugs that line up with them.
I will have the completed jugs and heads back on Thursday or Friday.
I will say, that the gasket I removed coverd the hole.
Hey Traildog,
You will have to take a good look at the heads,jugs and block to be sure that there is a place for oil to return properly. NO you cannot use a metal plug for the hole (if not required) it will leak and cause you problems down the road as it has appeared to already, you have to use a epoxy of some sort. As I stated before I have never done this so you should look for more info seems to be pros and cons with either set-up. Try this link http://harleytechtalk.org/htt/index....html#msg324336
Not sure if they will allow it to be posted so let me know.
Cheers,

Thanks, the link worked fine. Both heads, jugs and blocks have oil returns on the opposite side of where the mysterious hole is.
Thing is, it had a flat "plug" in it when I opened her up and the base gasket covered the hole.
