Coolant mixing with oil

Clearly you are assuming the head gasket is the issue. You can try a sealant but I have never had them work. There are some reports on this site of people having success with Blue Devil Head Gasket repair. I have not had the chance to try this yet but others have and reported it worked.

Before we go down that route, let's confirm the head gasket but running through these guides. I attached the video as well it you don't want to read through the info.

Let me know if you confirm the head gasket and we can go to the next steps. Thanks

I have read both of those and watch the video before I posted my question. My coolant level after topping it off completely full after driving home from work was extremely low as well as chocolate milk foam 3/4 of the way up the dipstick.

Okay. I think it is safe to say you have a head gasket issue. The issue you have at this point is which bank, front or rear? To find this we need to do a compression check or cylinder leakage test to identify which cylinders unless you want to do both banks. Clearly it is only necessary to do the one that is failed so I would highly suggest trying to narrow this down.

I included the process for both heads in case you choose to just do both sides.

Let me know what questions you have.
