i cant start my hatchback so i pulled the plus and there all filled with oil and i checked the seals under the valve cover. did i blow a piston or ring or what?

 

if there is oil in ur spark plugs tubes, the tube seals at the bottom of ur valve cover gasket are probably leakin, and when oil soaks plugs it will eventually foul the plugs, so my advice would be buy a valve cover set and some new plugs and se how far it gets you

 

If you want to know if you have good rings or not you can do a leak down on the motor and that will give you a pretty good idea on what is going on. Does the car burn any oil or smoke under hard acceleration at all. If you do then you can try switching to a slightly thicker oil like a 10-30 or 10-40 and it should help !
