Since you are experiencing oil usage..you might want to pull the EGR Valve and spray out the valve and tube to clear out any carbon build-up. It is not known for sure if either of these actions will affect your oil usage. I can only say my VX did use more oil than normal on one occasion and by changing the PCV it went back to normal usage (about 1/3 quart in 3,000 miles)
