Trying to decide if it's worth the money to rebuild or replace the engine. Using oil sometimes 1qt as low as every 400 miles sometimes as high as 850 miles. Vehicle is in decent shape and until now has had no mechanical problems over 2 years and 48,000 miles. Replaced the EGR and PVC hoping this would lessen oil consumption but no luck. Rebuild or new engine would cost me what or more then it's current value trade in or private party. I like it but not sure if I want to throw this much money into it. Anyone have any ideas?
