have somone drive behind you and look to see if there is blue smoke coming out of your tail pipe as you drive normally. if there is, its either your valves or rings, and you can check that with a comp or leak down test.

if there is no smoke then it could be an simple oil leak from a gasket somewhere. they can be tricky to track down sometimes.

she just had a new VC gasket put on. When she downshifts or goes into gear from idle (cruising) a little puff comes out, not much though. It's strange, I wouldn't think it burns so much oil but there's really no leaks around the motor that would cause her to lose so much oil. She does drive above 3K rpms often though...

then i would do a leak down test before pulling the head off. it would suck to do all that work and then later find out that it was something totally unrelated to the head causing the problem. at almost 180,000 miles on the motor, you could have more then one thing to fix to get rid of the problem.

For the record, I've got 242,000 miles on my baby, and she burns about a quart every 3000 miles. Faster (1q every 1500mi) if I'm doing 90%+ freeway driving. I'm pretty anal retentive about my servicing, and only use good quality (notice I didn't say high priced or synthetic) oil & filters. I also use 1/2q of ATF to flush my system about 200 miles before every other oil change. I have no idea what my compression is, but for 240k+, my little 1.8L seems to be fairly happy / peppy.

theres nothing else wrong with the motor, its in great condition. every mechanic I've asked to look at the car can't believe how many miles are on it, they say it runs incredibly smooth and has been very well taken care of. the compression is consistent, it just goes through a lot of oil.

I don't accelerate that fast either (uh... usually

), so maybe I'm getting less blow by on my rings then? A bad (or worn) PCV valve will allow too much oil vapor to blow out of the crank case, and burn off....

Only other thing I can think of is pure luck... maybe I just got a really well built engine?
