hello folks, my mom just got herself a 1987 Dodge Ram 50 2.6 liter non-turbo rear wheel drive truck. 2 weeks ago it started overheating, bubble noises where coming out of the radiator reservoir, and when i opened up the radiator I found this weird creamy stuff all over the inside of it. I suspected a blown head gasket, so i checked the compression but they are all around 120. Anybody ever experience this? what did you do? how did you fix it? Any help would be greatly appreciated thanks.
