Hello! Welcome to justanswer!

Well the only thing that leaks oil on the manifolds are the valve cover seals. They last about 5 years and go further like now... Thats the repair you need now. Meaning they can only make it smell in the heater or ac.

Thats could still be a valve cover. Dye should be added to the oil so a black light and a viewer can see the leaks origin. In the middle is usually a rear main seal.

Both jobs are expensive so dye should be added to the oil and a black light used to find the cause.....
