Hi had a mate round to fit new cam cover gasket he took everything of except one nut it is a star and all the others are hex the star nut is front side of the oil filler and flush in a recess and he did not have socket to fit in the small recess as the sockets are to wide is there a socket thatwill fit ?  :'(

I have a feeling it will be the recessed one under the oil filler your talking about. You have to remove the oil filler neck to get at it, if you look under the bit of chunky wiring loom you will see a little raised lip, lift that and twist the filler neck anti clock wise :y

Thanks ill have a go again tomorrow  :y
