nestorb98, I have never replaced valve stem seals so I can't provide any advice with that job. With that much oil consumption it's a good idea to replace the valve stem seals.

Recommend buying Bosch or Beru spark plug wires. Apply a light coat of dielectric grease on the inside of each rubber boot to facilitate future removal. I apply a small dab to a Q-tip, then smear the dielectric grease inside the boot.
