btw, my car is burning 2 quarts every 2-3 weeks, i feel your pain! i am fixing the problem in the mechanic program i'm in. it should be fun!
The valve stem seals will only leak during vacuum conditions. Yes, vtec burns oil, but with the abnormally large amount being burned, I tend to believe something is wrong.
A piston ring install isn't that hard, it is just very labor intensive. The head needs to be pulled, oil pan dropped, and the pistons pushed out to access the rings. Honing can be done with the block in the car with a drill and the proper stones (400 grit) as long as care is taken not to hit the crank and thoroughly clean the bores afterwards. It took me 10 hours working by myself to do it in my garage, so it isn't the end of the world.
The danger of not fixing the problem is that the oil consumption will starve the engine of oil if the oil level is not properly maintained. You can also kiss your catalytic converter goodbye if you let it burn too long.
