Hi there I have a 1996 honda oddysee ( 107 k miles)that has an oil consumption problem. It uses about a quart of oil every 1,000 miles. It also turns black within 1,000 miles after an oil change. I had the front crank seal changed with the timing belt service (104 service recomendation)and that helped a little oil leak that it had at the time. this car doesn't smoke and it passes DEQ just fine. any ideas
