the oil is mixed with the coolant and dont know why it is happening, could it be because of the car overheated, whic is strange due to the fact that never seen it over heat.

The engine doesn't need to overheat to have a blown head gasket, even though that is often the cause. You can have oil and coolant mix from a leaking intake manifold or oil cooler as well, so get those checked first.
i have a 97 cadillac catera if it has a blown head gasket will it start
hey if the oil cooler happen to mess up would my engine oil have water
the internal oil cooler has blown a seal, like the lower answer page buy an aftermarket oil cooler and replace the system. if there is only oil in the coolant then that is your problem. if water is in the oil at the pan then you have that as well as a head gasket. the after market oil cooler system from hayden part number hdn 459 is about 99 $ @ your local parts store or 65 $ @ hayden car parts . com.
i had tj same prolem... its the intercooler located righ in the midle of the motor.. on top.. but u gonna have to take ur radiator to be clean after u intall the part... oh and the part cost me 450 dollars...
if the intercooler is leaking oil into the coolant does this make it over heat, or does this also lead to blown head gasket..I would like to fix the oil cooler first and hope the head gasket is ok...2000 catera
I SOLVED MY PROBLEM BY RUNNING A EXTERNAL OIL COOLER, I HAD TO MODIFY THE COOLER LINES BY GETTING THEM REDUCED TO MATCH THE LINES ON THE EXTERNAL COOLER . YES, I DID HAVE TO CUT AND REMOVE THE LINES FROM THE OIL PUMP AND HAVE AN EXTENSIONS WELDED ON, MAKE SURE YOU HAVE THE CORRECT ANGLES SO THAT YOUR LINES WILL CONNECT, YOU MAY HAVE TO CUT A LITTLE OFF THE LINES. I ALSO USED THE METAL LINES ATTACHED TO THE USED TRANSMISSION COOLER. YOU MUST USE THE METAL LINES BECAUSE OF THE PRESSURE. I SAVED ABOUT 800.00 DOLLARS,RUNS GREAT, I DID HAVE TO FLUSH SYSTEM THREE TIMES. NOT AS COMPLICATED AS IT SEEMS, DOUBLE CLAMP HIGH PRESSURE HOSES THAT YOU WILL NEED TO CONNECT THE METAL LINES TOGETHER, MY OIL COOLER NOW SITS ON THE SIDE OF MY FAN. YOU CAN STABILIZE THE COOLER WITH PLASTIC TIES. YOU MUST REMOVE THE BOTTOM PLASTIC COVER TO EXPOSE YOUR WORK AREA. THE ROUTING OF THE LINES SHOULD RUN ALONG THE SIDE OF THE COMPRESSOR, DON'T GET FRUSTRATED, IT WILL TAKE A LITTLE TIME, BUT IS WELL WORTH SAVING YOUR VEHICLE. THE REASON YOU MUST MODIFY LINES, THEY ARE 7/16 AND YOU WILL NOT BE ABLE TO FIND HIGH PRESSURE THAT IS TWO SIDED, THE COOLER LINES ARE 3/8, DON'T SHORTCUT IT WILL BLOW THE LINES OFF(PRESSURE).
