Oil in my Radiator......Some say cracked head others say it's not a cracked head?

1997 NeonOil in my Radiator......Some say cracked head others say it's not a cracked head?
i own a repair shop ,and a cracked head will be opposite,it will put anti freeze in the oil,if it has a cracked head it wont be mixing oil in the radiator on it,it would probably be mixing coolant in the oil,the only thing that might have happened to it is the inner cooler in the radiator could be leaking and adding transmission fluid in the radiator,and that will appear as oil ,but unless oil was just poured in it,it would be really hard to get oil in the radiator on it,good luck,hope this helps.PS the inside pressure of the engine will sometime push a small amount of oil in to the coolant chamber,but not a lot,if its got a lot of miles on it,you might want to consider another engine f or it,or get rid of it,good luck.Oil in my Radiator......Some say cracked head others say it's not a cracked head?

Does the car have a turbo? Could be coming from an oil cooler. Could be a cracked head or a cracked cylinder. Are you sure its motor oil and not trans fluid? Either way your car has problems and needs looked at by a professional.
It sounds like a cracked head to me, as I can't think of any other way you can get oil in the radiator aside from just pouring it in there.
two other things could cause this issue one is if it is a automatic transmission you can have a cracked oil cooer and you are leaking transmission fluid into the raditor, and it is possible but not very likely you have a intake manifold leakage. but thats rare.
Sounds like some serious problem. Have it looked into before you are stranded on the road with no transportation. Good luck.
a cracked head will do this also but if the trans coolor cracked it will let trans oil into the rad is it engine oil ?? u dident specifiy
I had the same problem with my car- a 1994 Sable...as long as it's just oil in the radiator and not water in the actual oil, then it shouldn't be a super-serious (AKA $1000 to fix) problem!


I got a new radiator (Glad it was my radiator that was cracked, and not the head!), and then flushed the radiator- using Prestone super flush- and am about to put some stopleak in the cooling system... hopefully that will do the trick. It's what my dad told me to do and he's worked on cars for years- and used to have a car like mine lol hope I helped! ;)
Cracked head or not, it IS a major problem. Could also be a bad head gasket, but not much difference there! I had an old chevy that pumped ALL of its oil into the cooling system, then I had a cracked head and a blown connecting rod. Whatever is doing it, its almost a certainty the head will have to come off and the radiator be ';boiled out';.
ahh neons there pretty much toss away cars not ment to last any ways , just change the motor and start fresh beacuse you dont kno what else is wrong with the motor
Someone could have added it to stop a leak or blown gasket. Bars Leak sealer has water soluble oil in it and looks and feels very oily. I have some in mine I'm trying to flush out, very messy!





or it could be a cracked radiator letting in fluid from the trans cooler which is inside the radiator on automatic equipped cars
assuming your car is an automatic first check trans fluid level %26amp; condition ,,most likely cause ...... the radiator gave out/cracked between coolant %26amp; trans cooler tank on side of radiator..!!DONT DRIVE the car too far if coolant is entering transmission youll be in bad shape!!! good luck!!! PS: have trans flush after new radiator...
don't have to be a craked head, Good possiblity that its just a blown head gasket.





Either way it's a job, Just getting the head off to verify.
There is no other way for oil to get into a radiator other then a craked head. Unless you pour oil instead of radiator fluid into it.
Those heads aren't always what they're CRACKED up to be.
