2001 Honda Accord

Having just passed my test, I've been handed the keys to my Gran's old Honda Accord. It really goes well with less than 70k on the clock after 8 years. The engine still feels great. However I've noticed that after some hard revving (>5500) there is sometimes a small amount of black smoke from the exhaust. Is this the normal "Vtec Smoke" which has been reported?

every mother's car produces black smoke when revved by his just licensed son, no atter what the car is (or half the cases [I]was[/I]).
