With a quick google this is the best pic I can find for you. Ignore the circle in the pic. See the Injector in the pic. Its right angled. The injector goes down into the head and the short right angled arm come out at 90degrees'ish through the side of the head. This is whee they leak from. <img src="http://www.nissanpatrol.com.au/forums/attachment.php?attachmentid=68686"/>
Thanks mate, didn't know the zd30's were set up like that. Do you know what was the advantage to being on the side?
