I have a 2003 Honda Civic with 180k miles and Im losing about 1 1/2 quarts of oil every 700 miles. It drives and idles fine and no sign of oil under the car. I did compression check on each cylinder and they all came back within range. Recently I started noticing a puff of smoke coming out of my tailpipe after idling at a stop light (doesnt do it at every stop light).

Could this possibly be a head problem? Its not overheating and Im not losing any coolant...the only problem is the oil consumption.

It's most likely the oil rings. You can pull them out the bottom clean the pistons, re-ring them and throw them back in

The cat is hiding most of the smoke, this will kill it eventually

What oil are you running? That car calls for 5w20 correct? If that was my car I'd put it on a good high mileage oil and bump it up to a little heavier of an oil depending on what youre running now.
