Yeah, these things vaporize the oil and consume if I remember seeing that on here before. almost 1/2 qt here every 3K.

Just go to ebay and search catch can and you see a bunch of different pictures and such. As far as the breathers just take the pcv line off of the drivers side valve cover and the top of the intake,get a k&n breather that fits the hole in the valve cover and put a vacuum cap over nipple on the intake.
you could try switching oils. when i went from mobil 1 to royal purple i noticed my motor drinks alot more rp than m1. went from 1 quart every 3k of mobil 1 to about a quart every 1k miles with the RP. these motors seem to gulp down the royal purple.

Your '03 should already have the fixed orifice PCV valve. Here's the info from Rockauto.com:Quote:

my last two motors didnt consume any oil, id didnt route the fumes back into the motor either. Also routing the fumes which can also be oil vapors can lead to detonation. oil doesnt mix well in the combustion chamber
what size breathers are needed as far as the part that goes in the valve cover?Quote:
