Lots of good suggestions here. One that hasn't been mentioned is Walt's observation. The threaded holes for lower studs on the cam housing are not blind holes. They pass thru all the way into the cam housing where the oil sloshes around. If the sealant on the threads is not good, the oil can migrate to the outside and no gasket, special washer or sealant is going to stop it. The only stopper is the nylock ring on the nut. But if you seal the threads in the cam housing, you're stopping the leak at its source.

Walt had actually suggested using acorn-style nuts (top of nut is capped, not exposed). Good suggestion if one is not prepared to remove the studs and seal them up.
Take a look at the washers I suggested. They will stop the leak as you describe it here because the rubber seal is at the junction of the thread on the studs as it leaves the housing. I think if you saw them as installed or thought about it you would agree with me......unless I am missing something.
