From looking at your pictures I think you could repair the damage. Parts from the wreckers are pretty cheap & it's not much more than unbolting the damaged pieces & bolting on the undamaged ones. Of course with it needing tires & maybe other repairs, you'll have to decide if it is worth the effort. Just as an added fix - your burnt oil smell may be coming from the valve cover gasket which leaks oil onto the exhaust manifold. Another easy fix but a little patience is needed to fix it. If you decide to go ahead & need some pointers just shoot me an email.
