For 2.5 years I had the car almost no oil needed to be added between changes. 5 month ago I had the head gusket replaced. The tech also talked me into valve job. Car had 96k at that time.
As far as I see, car uses a quart of oil every 1,000 miles or so since gusket replacement and the valve job. I run Castrol synthetic blend in it and the engine is 104, 24 valve.
What might be cousing this?
