Hi Justin,

More than likely you have a blown head gasket but there are some other things that can cause this.

Here is a guide that will run you through the basics:

Just because it doesn't overheat doesn't mean it is not a head gasket issue. I would recommend performing the tests listed in the video to confirm a head gasket. Just based on experience, I doubt it is anything else but a head gasket issue.

Let me know if you need anything else and I will be happy to assist. If you want me to send you the process for replacing these, let me know which engine you have. 3.9L or 4.2L.

Thanks
