Motor Oil In Radiator

Posted by LOL On 2020/10/18 18:30:59

Hi All,

I keep seeing a film of motor oil in my radiator. I have replaced the head gasket, had the radiator re-cored and just today I took the car out and there was a considerable amount of oil floating to the top of the radiator.

I also notice a white foamy film on the inside of the radiator cap after driving the car.

I realize it could be a few different things wrong but I'm leaning towards this thing (please see yellow arrow in picture).

I don't know what this thing is but I do know it has both motor oil and antifreeze flowing through it. I'm guessing it's either an oil warmer for cold climates or an oil cooler ... 50/50 chance ... lol ...

I would appreciate hearing your thoughts and past experiences and hopefully resolutions to this matter.

Thank you in advance,
Crin
