When I last posted, I had decided to accept Honda's offer to repair the
blown crank seal and give me an extended warranty. (The original post is
copied below.) Since that time I have been tracking the gas mileage, as a
possible way to see if there is any engine damage. I am now quite sure that
there was damage and it has increased the engine friction.
Prior to the oil leak, I drove a total of 900 miles. The mileage, as
indicated on the dashboard, was 19.8 mpg. I just tracked the mileage over
two fillups. The mileage is now 18.5. This is a decrease of 6.5%. Both of
these figures are over the same suburban roads, doing the same errands, day
after day. This is a statistically significant change, and the only
explanation for it is internal engine damager. (I verified that the
dashboard indicator is correct, by comparing it to my own calculations from
the pump. The indicated mpg is within 0.5% of the calculated mpg. I also
verified the car's odometer against measured mile sticks.)
I plan to contact Honda and ask for a new engine or a new car.

I have a one-month old 07 CRV with about 900 miles. Last night I noticed
the oil light blinking randomly. I checked the oil level as soon as I got
home, just a couple miles later. It was down, so I added a quart. I did
another short errand (5 miles), then checked the oil again. Still low, so I
added another quart and parked it for the night. This morning I checked the
stick and it showed nothing. So I added two more quarts, bringing the level
up to full (2nd hole in the stick). I drove the car directly to the dealer
this morning (about 5 miles) with no oil light coming on.
I now realize that the oil has been running out for a week or more. There
are oil spots where I park my car at work, and two large spots in my
driveway. The oil level was down 4 quarts!
