its normal in any average to high mileaged vtec motor...since the vtec is activated by oil pressure..it is usually attributed to seals allowing oil to leak into the cylinders...take out the spark plugs and see if they are covered in oil...sometimes piston rings depending on the mileage

The only time I've seen that is like the guy above me said, the seals, more importantly the valve seals. It could be a number of them but I've seen it on a couple of cars as being the valve seals.
