oil loss of quart per 100mi cannot find!

[pete p]

I am lossing a battle with oil consumption and hope someone has a new direction for me to go. Every 100mi I lose a quart of oil. there is a little in the valley and maybe a drop or two when the vehicle sits overnight. Had it to a garage that is very good and their stumped as well. Doubt its burning that much because of no new smoke patterns? Help if able before I go crazy! Pete p

You forgot to post the Yr/Mdl/Engine of your truck

Ah yes I did neglect those...Its an 02 F-350 dually with a 7.3 Thanks!

These engines can burn a lot of oil and still not smoke. Not saying that's your issue, I'm just saying that I would believe its possible to burn a quart ever 100 miles and not have much noticeable smoke. How sudden of an issue is this? did it just happen one day?

check your coolent your oil might be going there. if your oil is going into your coolent you have a bad oil cooler or your orings in your oil cooler are shot.

absolutely agree with this possibility. only thing is usually it will smoke blue like a banshee if it is the case.
OP, remove the fuel filter. have a look in that fuel bowl.
