so i havent replaced the valve seals yet but i found out after driving non stop for about 9 hours that my car is constantly burning oil. i filled it to the max before leaving, and when i came back 600 miles later, more than a quart was gone! im afraid it might be piston rings

but the wierd thing is, im not blowng smoke out my exhaust the whole time im driving. when i first start the car in the morning that is the only time it will blow smoke, but goes away in moments. I also found out that the thin hose thats connected from my head to my intake actually contains some oil in it?? wtf?? i dont think that its supposed to have oil in it... Is oil leaking through into my intake, sucking it into the intake manifold, and causing it to burn oil?? and maybe that is why i get that cloud of smoke in the morning, after all the oil is dryed up. Is that possible?? any suggestions ppl?? some advice? thanks.
P.S. dont forget that my compression is fine... so piston rings should be fine... right??
this is the pic of the hose...
