It should be torqued up in two stages,the first stage is 3-6 Nm,and, as mentioned already, the second stage is 12 to 18 Nm.The bolts also have to be tightened in a special sequence too,otherwise the manifold can be warped which can cause the inlet manifold gaskets to blow out or leak prematurely.This is where the gregorys workshop manuals come in handy.They show all this stuff.
