How common is it for the valve stem seals to be a major source of
oil burn? My coupe is buring (I'm absolutely positive it's NOT a
leak) about 1qt/300mi. The ground under my car at work (assigned
parking-same each day) will only have 2-4 tiny drops of oil, the
rear underside, bumper, and backend of my coupe are dry and clean.
While on my SD (I know it's leaking from the turbo return pipe and
braided line) the rear bumper and trunk shows oil splatter. I've
read the manual *.pdf's (05-270, 05-235, and 05-250) and it seems
to be an easy job and the parts are less than $25 from Rusty. Any
thoughts on this? TIA all,

You will need to employ some method of keeping the valves from
falling into the engine. Constant air pressure is the best way to
accomplish this.
I would do a little diagnostic work before throwing parts at it in
hopes of solving a problem. There are so many things that can cause
excessive consumption. Usually you will find several contributing
factors.
Valve seals are not a simple little job either. Essentially, you
will be tearing down the head while its mounted on the block. Are you
seeing blue smoke? You should using a Qt/300 miles. Do you keep the
level 1/2 way between the add and full lines. This really does make a
big difference.
