I have a 05 Taurus 3.o Thats burning oil .Car runs great but smokes a little and burns about a quart of oil about every two weeks. Could it be something besides the head gasket?
The oil is either coming up past the piston rings, or going by the valve seats. Try using a 10w30 oil weight.
Usually the headgaskets blow long before you start having problems with oil consumption, so no it is not headgaskets causing your problem, worn out rings, valve guides and valve seals is the most likely causes. You can try a heavier weight oil and then add some engine restore to the engine oil but it is only a temporary fix, eventually you will have to have the engine overhauled or replaced to fix the problem, and that will be more than the vehicle is worth unless your going to keep it until the doors rust and fall off.
If its a steady smoking and never changes or is not heavier at start up then may be rings, if its heavier smoking at start up sounds like valve seals which would be a easier fix and worth it to do. Heavier oil will help to a certain extent, if it still smokes about the heaviest oil you can choose is 20w50. Could try a oil designed for older engines. Try Lucas Engine Oil Stop Leak it is designed for worn valves stem seals.
