Its either a leaking base basket, or rocker box gasket leaking to the bottom and bubbling. Either way you need to rotate the engine to get to those bolts. Its not a hard job to do if you are handy with a wrench at all. Just get yourself the james gasket (JGI-17049-04-X) set and freshen the gaskets up. And if its that bad I would not wait till winter!
There are 4 large chrome cap bolts 2 are in the open and 2 are under the rocker box so you gotta remove the rocker box to get to those anyway.
Heres a how-to thread on engine rotation
