Coolant found in motor oil what causes this??

[arizona7.3]

Did a blackstone test on my motor oil and they found coolant in my engine oil.


What could be the cause of this?

1. Oil cooler?

2. Injector cups?

3. Injector orings?

4. Need a new motor??


Thanks guys.... Motor runs fine, on the scanner it read bad CPS and high EBP sensor readings. It smokes white at idle, but the coolant level stays the same??

I'd say oil cooler first. Not a hard fix but the new o-rings get pricy (there are a couple YouTube vids to show you how to fix). The oil cooler can crack internally also. Then I'd go with worn injector cups. Seen this a bunch on SD's.

I second oil cooler. I had a leak(external) and though it was o-rings. Replaced them put all back together to find out it was the oil cooler itself. Pin hole under the rust. WTF!!! If you have the $$ I'd replace the whole thing and save yourself my headache taking it apart twice.

Oil cooler gasket. Did mine in January. $150 from ford for 2 gaskets and 2 I rings... If you don't split the cooler you only need 2 gaskets about $70 for the pair.. The orings were about $25 each. Simple to change.

Redid my oil cooler about 5 months ago. it was doing the exact same thing... Now, though, I have this gloopy mud-color substance in my coolant tank. You guys think it's shot again, or should I just flush the coolant one more time?
