If the dirty water is rinsed into that opening, it will pool in the spark plug/coil ports which are about 6-7" deep. This can short out the coils. If the coils survive, the water will evaporate once the engine is run for a few minutes, but all the gunk that was rinsed off will be left in the ports. Now you run the risk of this crap falling into the cylinder the next time you go to change your plugs.
By the way, I tried Black Magic 2-in-1 Engine Shine and was pretty impressed with the results. It's gentle on aluminum, it did an amazing job cutting through the grime (only a few heavy spots needed a scrub with a toothbrush), it left a nice shine on all the metal and black plastic parts after the water rinse, and it seems to replell dust and dirt. I only mention this since it is rare to find a cheap product that surpasses your expectations. Hopefully you can find it Down Under.

Is this for the n54 or n55 or both where you need to be careful with hosing down the bay where the filler cap is?
