With some luck, it'll only be the caps at the rear of the towers that are the source. These have their own gaskets and can be readily changed with a 1/4-drive 10mm socket. Small hands also help:) (all of which requires air box removal, of course).

If it is in fact the gasket between the tower and the head, the manual says you can remove the tower (heads too) with the engine in the car. It'll be a bear and be ready with the magnet to extract the 6 (per side) allen head bolts accessed thru the holes in the tower. Once you loosen them, unless the allen wrench is magnetic, the angle will probably result in the bolt falling off the socket as you try to extract it. No big deal, except when you try install them.

Hopefully, it'll be the more commonly found rear cap leak.
