While waiting for parts, I'm flushing the cooling system. While draining, it started out with nice clear green fluid, but now I'm getting this camo-green goo reluctantly dripping out. Sure glad I'm flushing it out. I'm guessing it's oil/water mix. I'm thinking of doing the first flush with Simple G...

Thank you for looking and your quick reply. You have relieved me of my worries.
It was a pretty busy 4th of July weekend on the Apple River.....not so today.

I just bought a 1982 Honda GL1100 Goldwing and I am replacing the left side head gasket. Upon close examination, there appears to be an irregular hole near where the left motor case and transmission cover meet. I have pictures attached. Do I need to be concerned?
