Ok. Just had it replaced along with the hose and gaskets. Parts were $110. Labor was $200 (friend rate for about 5 hours) because he also fixed my clutch pedal. I think I made off pretty well money-wise. The valve did pour oil out when it was taken out and so far after a day of driving the oil seems to be right where it was when I filled it. Lets hope this continues throughout the week.

Was still losing oil (slower rate) after everything was changed. Went to change my spark plugs and found quite a bit of oil in the plug holes and the plugs were black... Changed valve cover gasket and oil seems to be staying consistent. Anyone else have any other suggestions on where it could be going? No black buildup on the rear bumper above the tail pipes either.

Cars that drip while running usually coat the floor pan and at highway speed will tag the bumper and rear of the car with oil spots. If its not there, its on the ground somewhere so you need to look until you find it (up on a lift???)!

How often do you all change your oil anyway? They can be burning it; and if so change it more often and rev it a tad more, add some Techron fuel cleaner at least three times a year and bump the OCI to 4K max, this can help reduce oil consumption.

Dry as a bone. I change between 3k to 5k (depends on weather, no garage). A friend at the ford dealership in town wants to look into it. When it goes in, i'll post more info.

KWhale: I have a 2003 6i with 116k miles with the same issues you are having, including the surging part when first starting up. I'm taking my car in tomorrow to have this looked at. But, did you ever resolve what was happening with yours? I sure would like to know if you came with a solution before I start spending the money for them to figure it out.

Still not sure what it is. Changed my oil using quaker state 5w-20 and a bottle of Lucas Oil Stabilizer. Seems to have slowed it quite a bit. Not putting as much in as I use to.

OK, thanks. So you think that replacing the PCV valve might've helped slow down the oil consumption a bit? I'll pass this along to my mechanic about looking into that.

Yeah and they are known for going bad. the valve and hose are pretty cheap at the dealership too.
