I have oil in my coolant reservoir of my Range Rover Sport 2005 . I would like to know where is it come from? Could it just be some oil cooler leaks to water system, cause it has higher pressure than coolant system or some other coolers from the suspension dynamic system. My engine oil is clean ( no water in there), or is it the head gasket or it might be something else entirely ..
Note: this issue has happened while the car is running in ideal at the garage. there was no indication of over heating the engine. temperature indicator still show normal values even now when I start the engine with the current failure condition. but the oil will be flowing to my coolant reservoir.
please Gide me to investigate this issue ,I hope it is NOT the head gasket.
with my best regards ,,,
