as above,and when refitting manifold, theres a tool to help line up the ventilator/breather box in the middle of the manifold-if u look though, the box just slides into grooves in the manifold,so when lowering manifold on just reach in with (large) hand and hold it in.On removal of manifold,there are 2 small torx bolts through brackets underneath into manifold-rear one was easy with long quarter extensions but front one i had to fix small torx bit into miniature spanner-5 hrs should do it.
