Odd story...I cracked a block one time, so anti-freeze got in the
oil. When I pulled everything apart, I found pure anti-freeze behind the cam...between the cam and the rear cam plug. Have no idea how it seperated from teh
oil back there, but there it was.
So, if you have even a minor coolant leak somewhere, you could have some leaking out the back cam plug if it isn't sealed correctly.
Two problems at once.....nice.......hope you find a minor problem and an easy cure.
ps: pressure test your rad and look for coolant leaks first. Fix that and you may only have a bit of
oil leaking after that, and that's OK as most FEs leak "SOMEWHERE"!!!!!!
