Does intake manifold need to be torqued?
Over tightening can damage the seal or cause the manifold to warp. Any thing that has a seal should absolutely be torqued to spec. Anything that has a torque spec; which is really everything should be to avoid snapped of bolts or things falling off from fasteners loosing over time do to vibration.
What are the torque specs for an exhaust manifold?
The standard is to use 20 to 30 foot-pounds of torque. Older engines often fall on the lighter side of the equation, so use 15 to 20 foot-pounds of torque if your engine is 15 years old or older. Some manifolds house different sensors and plugs, such as a check valve or exhaust plug.
What is torque sequence?
Bolt tightening sequence, or torque sequence, is defined in the torque tightening procedure. Flange joints are torqued tight with the help of a torque wrench (manual or hydraulic). Torque bolts and nuts in a “CRISS-CROSS” sequence using a minimum of three torquing passes and the maximum bolt stress as defined.
How do you torque a manifold?
Torque Sequence Hand-tighten all bolts initially. Torque the bolts in sequence to half the amount of torque necessary. Start with the middle bolts, and work your way toward the edges one bolt at a time. Repeat the process using the full torque necessary.
How tight should my intake manifold bolts be?
An oil leak may result if the vertical bolts are not tightened before the diagonal bolts on the lower intake manifold. Tighten the lower vertical intake manifold bolts to 115 inch-pounds (13 Nm), then tighten the lower diagonal intake manifold bolts to 115 inch-pounds (13 Nm).
