I agree with Mark.. i was burning about one quart every 1k miles. I changed the two o-rings on the air oil seperator (oil fill tube) aswell as the dip-stick o-ring and adressed a few other things while in the area. I am now only burning about 1qt every 3k miles. Still not spectacular but much better than before.
Just today however i pulled the j-boot (doing the headgasket) and noticed oil had pooled in the throttle body..though the throttle body was not nearly as bad looking as it used to be before i changed the o-rings. I have yet to change the o-ring on the oil fill cap, hopefully adressing that will fix the problem further.
What were the exact numbers on the compression test? Did you do a 'wet' test? Usually if you add a tea-spoon of oil into the spark plug hole and redo the test, if your compression numbers shoot up drastically this usually means you have worn piston rings. However i have read before the piston rings on these cars are fairly tough and do not fail all to often. Addressing the o-rings is a much cheaper job than changing the piston rings. Its a pain in the butt to remove the intake manifold and the fuel rail..but for the piston rings you are looking at removal of most of the front suspension, dropping the cross member and oil pan and a few other things....much more work.
