So the oil cooler took a crap on my 95 4x4 f250 7.3. At least i think it did because its leaking oil and theres oil in my coolant. I mean the radiator looks like theres mud in it.. yeah its bad.. but what i want to know is if putting new o rings and gaskets on the cooler will stop this problem. like i know im gonna have to flush my radiator and do an oil change but will the problem persist if i just rebuild my oil cooler? Any help on this will be greatly appriciated guys. i cant afford the $900 bill on this so i have to try and do it myself to save some money
