Oil Leak?

[Nice rig]

I've lost about 1 quart since last oil change (about 4000 miles), I catch an occasional wiff of oil but I've gone underneath the truck, under the hood and can't find any signs of leakage. There is none on my driveway so I'm at a loss. Any ideas?? On a better note, I got my stainless steel brush guard back...except I had it powdercoated. Man it looks good:), wish I knew how to post pics.

If your loosing oil without it leaking, then your burning it. Pull the plugs, see if they are carboned up. You could also check the PCV to see if it is working correctly.

 

As for the pics, use a host like Photobucket.

Thanks for the reply...I was thinking PCV...just to double check, as long as the PCV rattles when you pull it out it's good right? I don't smell it in the exhaust, I smell it from the engine compartment. I'll try the photobucket thing when I get a chance.
