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.

Can you use blue RTV on intake manifold gasket?

RTV can act as a lubricant and cause the rubber gasket to slip out of place and split, creating an opportunity for leaks. ... Intake manifold gasket sets may contain a small tube of RTV. This RTV is not to be used on the gasket face, but rather where the bottom corners of the gasket meet the end seals to fill the gap.

Can a intake manifold leak cause overheating?

Engine overheating is another symptom of a possible issue with the intake manifold gaskets. A coolant leak will eventually lead to engine overheating when the coolant level drops too low, however there are instances where overheating can occur without any visible leaks.
