Oil seeping from head studs

[full pull]

I have noticed lately that there is oil on the exposed threads above the nut on my head studs. There are no oil leaks anywhere around them. I wiped them off the other day and now they are wet again. Its not alot to where it is running down the head, just enough to see that the treads are wet.

Anyone seen this before. The studs have been in for over 30,000 miles and the motors ready to roll over the 200K mark shortly.
