I purchased a 2004 f150 this summer i have been running into problems with the truck burning oil. It burns About A quart of oil a week and it only has 93,500 miles on it. It puffs a blue cloud for about 45 seconds to a minuet but i think it stops because the cats get up to temp to burn the oil blowing through the exhaust system. The truck runs smoothly and no ticks or knocks also no major oil leaks. Ive been to two ford dealerships in my area and neither of them have never heard of a truck with under 100,000 burning oil like mine does. Any Help would be greatly appreciated cause id like to get this thing fix before complete engine failure. Thanks Guys!!!!!!

it also kind of seems like it will burn the oil on start up at random I just tried getting a video to show you guys what i mean and nothing no blue smoke out of the exhaust one of the reasons that im stumped on this issue Thnaks again

You say a quart of oil per week, but how many miles are we talking in this amount of time? Not to ask an insulting question but any sign of leaks(oil spots on driveway ect)? Finally, not to open old arguments, but are you using the proper oil for this engine? The 04-05 in particular are VERY tempermental on such things.

Id say around 400 Miles give or take. No oil drips or puddles in the driveway or in my work paring lot. I used the 5w-20 Motocraft synthetic blend recommended by the person i bought it from. I used a Purolator Filter with the oil change this time. Im going to try to change the pcv Valve to see if this helps but with amount it uses i wouldnt think that that would be the problem but it wont hurt to try replacing it

I have an 05 that just started doing the same thing. The only places i can think of that usually burn oil are piston rings and dripping from the cylinder head. I cant imagine/hope that it wouldn't be piston rings with your low mileage. Keep us posted what you find out.

Valve seals can go bad. There are ways of checking them and they are not terrible to do. Tedious but not terrible.

Valve seals would be my first thought too since it's smoking on start up.

Try some lucas oil. The thicker stuff. Might slow or stop the issue for a while.

Also you can try restore. That stuff in the silver can. It works great to restore minor compression lost. Might help and all worth a shot.

Oil changes are cheaper than valve seal replacements.

I agree with the above, valve seals are a likely culprit, though while certainly possible, it isn't likely the rings are gone, unless that engine has been simply hammered on by the previous owner. And if it were in that bad a shape internally, it would probably not run as quiet as you say(no knocking ect.).

Keep us updated as to what you find!
