Hi, I have a '94 Volvo 850 that seems to be leaking coolant. I'm having to fill it up frequently, so I think it's a pretty serious leak. Another clue is that there is this white goopy stuff on my oil dip stick. Does that mean that coolant is leaking into my oil system? If so, from where? Maybe a head gasket? Let me know what you think!
Coolant can leak externally and internally, I would first get a cooling system pressure test done as this will locate any external leaks, do this first and see how you get on before removing the head, there are other test that can be done to help identify a head problem as well.
