Interesting. How do you determine this to be a small coolant leak? I'm not up to speed with how to analyze the numbers other than comparing them to what they should be and going on that they seemed high.
This is a rebuilt engine. Oil has been changed at miles 250, 500, 1000, and 1500 for break-in. Mostly short stop and go trips of 15 miles total or less with a once a week trip of about 40 miles highway. Rebuild was finished in August of this year, 2005.
Mostly gentle driving with no reving over...
