Hello, This question is for a 1998 S10 Blazer. I have oil getting into the radiator but not getting coolant in the oil? It has been suggested that it could be a head gasket but I'm wondering if that is the case why coolant isn't getting into the oil. The oil accumulates in the radiator at about .25 - .33 quarts per scheduled oil change. Could it be a faulty sensor?

Are you sure it is motor oil and not trans fluid?

No. Not sure! Although it leaks very little oil externally and as mentioned it appears to be using some oil and the exhaust pipe appears clean. It could be tranny fluid. I dont recall the tranny fluid ever being low when checked since I bought the vehicle about 2.5 Yrs ago. I'll have to keep an eye on that.

If it is engine oil, then it is from a bad head or intake gasket. If it is trans fluid, then the radiator has internal damage.

Let me know what you find or if you have other questions.
