what would cause oil consumption of 1 quart every 150 miles on 2002 Honda Accord

runs fine, does not leak, does not smoke, does not foul spark plugs and pcv is not stopped up

You sure about the amount of oil lost and at the mileage posted? How many miles on your Accord? Rethink the question, it just don't add up on a Honda! Wait awhile, maybe the Honda Tech. here can be more help.

Check the very bottom of the timing cover for any oil droplets, if front balance shaft seal came out , it will leak oil down there but most of it will blow back while driving and not leave a puddle under the car when shut off.
