Hey I was wondering if my car is the only 4.6 to be burning oil because it seems very uncommon from what i have searched. Since i bought the car with 36,000 miles on it and changed the cats out.. when the car warms up it puffs smoke out of the tail pipes usually after i pull out from a redlight. I thought valve seals but there is no smoke on a cold start up. A ford mechanic told me might be a stuck ring. The car has 97,000 miles on it now and still uses oil but not an insane amount. Just curious if anyone else has run across this prob or have any ideas of what it might be. Was thinking of putting some oil additive in because at this point till a rebuild what could it hurt. Just tired of having the car cleaned up nice and looking good and puffing smoke out like a piece of ****
