Hi. Thanks for asking your question and requesting me! I will try and help you out.
Unfortunately it could be the head. IF the head had worn valve guides, it can cause an oil consumption problem. I am sorry. I wish I had better news.
You could also have an injector causing this. They can fail and allow oil to enter the fuel system and be burned in the cylinders. If this is the case, you should notice a black tint to the fuel.
Please reply back if you need more help or have more questions. I am happy to assist.
