I keep having oil apear in my water/coolant line…I replaced the head gasket earlier this year after seeing such signs at that time. Although the car runs well with the new head gasket, there is still a milk chocolate colored oil residue that appears in my water tank. I think it is clogging up my water line. Where else could this oil be coming from if it is not from a head gasket problem?
There a cooler line inside the radiator for the transmission fluid. If this cooler line has developed a leak transmission fluid can leak into the radiator.
