I pulled my head today as I had developed a small leak in the gasket on the left of the front side between the head and cylinder. Whe I pulled the radiator hose that goes into the front of the head this is what I saw: It felt like rubber...like the radiator hose was disintegrating a little bit. When I drained the coolant it was perfect in appearance with no sign of any contamination so it must have stayed local. Also, when I pulled the head/cylinder the front left head/cylinder bolt was all oily and the threads for it in the case were full of oil. I stuffed a paper towel in there and soaked up the oil. Underneath the oil was some perfectly green coolant. Is this something that can be attributed just to the leaking head gasket?
