I own a 1993 Accord with about 300K on the Stock Bottom end. Ever since I acquired it back in 2015 with about 160K it has used about 1 to 1.5 Quarts of Oil in 3000 miles. I change the Oil every 3000 miles. Last year I pulled the Head and replaced it with a Junk Yard head from a doner that had about 150K miles on it. I removed and cleaned the valves, replaced the Valve Seals and seated the valves with valve grinding compound. (Took the Head to a machine shop to check for leaking) I used all OEM supplier (Victor Stone) gaskets and replaced the Head Bolts.
After the Head job the Engine still had the same oil consumption issue. However I couple weeks ago I took the car on it's first long Trip. Albuquerque to Fort Worth Texas (648 miles). I was in the middle of an oil change interval so I only topped off the oil before the trip. When I arrived in Fort Worth I waited until the next morning and checked the oil. I was a Full Quart Low!
I added a Quart before the Trip Back to Albuquerque, after I arrived, I waited until Morning and was shocked that the oil Level was still at the top of the dipstick. I changed the oil for a trip to Oklahoma City. I just arrived from the round Trip journey and the oil level did not change. Can a car stop consuming Oil? Any Theories?
