This would either mean your intake gaskets are leaking or headgaskets are leaking....Your best option is to have some dye added to coolant then run vehicle for awhile. Then pull off intake manifold and look for intake gasket leaks...If you can find some then replacing intake gasket will be fine, if not you will need to replace headgaskets....If you call around you could probably find someone who would do the gaskets for around $2000 which is still alot, but less then the value of the car and alot less then some shops might charge...Let me know if you have questions, thanks.
