Oil in radiator, blown head gasket?

Can you tell where the leaking coolant is coming from? At this point, if the engine has been overheated, and you're seeing oil in the coolant (and possible coolant in the oil, pop the oil cap and check for a chocolate milkshake like substance) then it's likely the headgasket has failed. This could have been from a low coolant level (leak lead to overheating) or if something was amiss when the heads were replaced. Whether it's worth replacing of course depends on the overall condition of the vehicle (does it need a lot more work?) and your personal attachment to it. These can be good cars with some care and the occasional fix, each situation is unique.
