coolant in oil
I am owner of a1986 k100rt with 34,000 + miles. I am getting suspicious over whether radiator coolant is showing up in the oil, or is it just condensation. At the start of the season, i noticed that the oil level was higher than when i last checked it ( 3/4 site glass ), it had risen to 7/8. I backed out the drain plug to remove what i thought was excessive amount of oil. what i found was approx. 20mil of a clear liquid before actual oil started to drain. At same time, i discovered that my radiator overflow tank was low. so i filled it with appropriate amount coolant. After another 200+ mile ride, i happened to notice sploshes and other unusual variations within the bullseye sight glass, plus had to put a small amount coolant into the coolant overflow tank. I did check to see if oil was floating on top within the overflow tank, but did not detect any. I not shure if its the oil/water pump seals, a head gasket/water jacket, or is it really just condensation?
