Gentlemen, I am reassembling my inlet manifold and induction housing assembly after sealing up a leak between the head and tappet block. Could any of you assist with the torque required between the head & inlet manifold and the inlet manifold and the induction housing?

If this subject was covered in the past I apologize for not being able to navigate to a forum history.

Grateful,

Stew has over 37 years of V12 experiance. He said he doesn't use a torque wrench here and goes by feel because there is no documented Jaguar torque requirement for the nuts (inlet manifold) and bolts (induction housing). He said if he had to guess he would say 25 ft. lb. on the nuts of the Inlet Manifold and 30 ft. lb. on the bolts of the Induction Housing.
