Thanks for the input, i will have to check the valve seal, i am leaking down the backside of the motor, i can see oil accumulating on the backside of the block and is trickling down to the pan. Originally i thought the seal for the pan was bad but it seems that the leak is happening higher up. It is also burning too, you can smell the burt oil when you pull the cap off when you put more in. Kind of a bitch to deal with since I have a bunch of tests/finals coming up.Mine had the same issue before the rebuild, probably valve seals. I got it down to one or two quarts every 3000 miles using Delo 15W-40.
After the rebuild I ran lighter oil over the winter, and I think I lost about a quart in 3000 miles even after breakin. Switched back to 15W-40 on the last change, and oil loss has been negligible.
