I would like you to check the compression on all cylinders to make sure if its headgasket/head related or something unrelated.

Thanks, I'm not able to do that as of now. I can tell you that it runs perfect, no hesitation, no over heating. How I found out about the mix is I took took into a local shop to have the oil changed and they told me that inside the radiator the oil cooler line had ruptured and told me to fix the problem it would need a new radiator ($1000) I continued to drive it for work putting over 1200 miles and still no overheating, not even an engine light. I did buy a new radiator and installed it yesterday, but I wanted to find out if its anything other than that, like I said it runs excellent

To me it sounds like your issue was due to the radiator and you should have nothign to worry about, if it starts mixing again let me know.
