[Madrox]

its a 4afe
its one of the 3 bolts that go down into the head that hold the cam cover in place. there are 2 on each each and one in the middle of the spark plugs.
i dont have a digi atm so no photo.
u have the bolt that comes up that has a nut on top.
a mate snaped the bolt including the thread in the nut.
we were thinking easy out to take out the bolt and replacing it asap and getting a new nut to put on the top.
