That would probably mean either the bolts are wicking coolant up, an o ring on the SC to LIM gasket is bad or your LIM gasket has failed and is leaking.
It'* not very common, but does happen. My suggestion would be to replace your LIM gaskets with the aluminum framed ones available from the dealer, the LIM to SC gasket from the local parts store ~$7 and the TB gasket from the same place. While you are at it..flush out the Dexcool and swap over to Prestone long life.
That should clear up your leaks, add a bit of maintenance and give you many miles of happiness.
