Very slow leak? or maybe I am burning it up in the engine?

It could be a number of things really. Have you pulled apart your intake to check all the hoses? I would suggest a compression and/or leakdown test to see if it might be your headgasket. I experienced the same issue for over a year and couldn't figure it out as all hoses were good and I could see no visible leaks after shutdown.

Two weeks ago after a long ride I saw coolant dripping onto the swaybar and then onto the ground forming a puddle. I pulled the belly pan, intake, belt covers and got her up on jackstands. Long story short....it was the waterpump that was leaking.

$1,500 and the problem is solved. I had all belts and pump replaced, resealed entire front of engine, replaced thermostats, oil pressure sender etc.

The leaks are gone but my wallet is empty. I'm SO glad I have my Civic for a daily driver. That car takes a beating and just keeps on going.

I had very nearly the same thing for about 2 years.. The hoses would be hard and then suddenly they would not be.. about a cup every 6-8 weeks. worse in the summer then in the winter.. Ended up a bad cap. no real coolant loss to see. but when the heat maxed out and the fans went on full go. I would get a wiff of antifreeze smell.. also found that I was having fan relay problems.. HTH..

Go to Autozone and borrow a collant system pressurizer. It helped me find two ponhole leeks in some hoses.

Worst case senario. Cracked head. I'm buying a new S2 head because of a mixing problem (coolant in oil). Analysis of the head showed that it was "fixed" at least 4 times, but they still found 2 cracks that was allowing coolant to seep into the oil (or out of the coolant passages into the head area).

Yup, I should have never bought that car.
