Inlet manifold torque specs

(V12 Dave) #1

Checked my manual and the archives and can’t find the torque specs for the nuts holding the inlet manifold down.
Aside from 2 or 3 grunts does anyone have the torque settings?
Thanks

I have the figure 25 Nm recorded. It is possible this is spec’d on the preHE and not in the HE manual.

Inlet manifold to cylinder head (nuts) … 23-27 Nm
Inlet manifold to cylinder head (bolts) … 23-27 Nm
EGR valve to throttle housing … 9.5-12 Nm
Elbow to inlet manifold … 12.2 Nm
