Intake manifold or head gasket? i know head gasket need a sequential order followed by how many degrees and Lbs of pressure. if its on the intake i doubt it needs an specific torque. just try not to crack the intake manifold since its made of plastic.

SOURCE: Front caliper securing bolts torque

I know that it's a jag, and I know you are trying to be perfect, but in over thirty years, I've never seen a tech put a torque wrench on a caliper bolt. If you really want to I'd use about 35-40 foot pounds. (I go by bolt diameter) You don't have to slam them down but you don't want them to back out either. A bit over 35 is reasonable and should not damage anything and will keep them secure!
I have no idea what nm conversion is..

Toquer on the intake


start in the center working in an expanding square pattern crossing over the manifold on the first 2 bolts. tighten in 3 steps. these are low torque fasteners, don't over tighten & use locktite.
If reusing the fasteners, apply threadlock GM P/N 12345382 or equivalent to the threads of the lower intake manifold bolts.
Install the lower intake manifold bolts.

Notice: Proper lower intake manifold fastener tightening sequence and torque is critical. Always follow the tightening sequence, and torque the intake manifold bolts using the 3 step method. Failing to do so may distort the crankshaft bearing bore alignment and cause damage to the crankshaft bearings.

Tighten the lower intake manifold bolts.

from front of engine tighten 2 bolt back left side, then 3rd bolt back right side, then 3 bolt back left side, then 2nd bolt back right side, then back bolt left side, back bolt right side, then front bolt left side, then front bolt right side

Tighten the bolts on the first pass in sequence (1-8) to 3 N·m (27 lb in).
Tighten the bolts on the second pass in sequence (1-8) to 12 N·m (106 lb in).
Tighten the bolts on the final pass in sequence (1-8) to 15 N·m (11 lb ft).

    Intake manifold gasket / replace


    3.8L Engine

    NOTE The 3.8L (VIN K) non-supercharged engine uses a two-piece intake manifold consisting of an upper air plenum which mounts the throttle body and a lower intake manifold assembly which houses the fuel injectors. The 3.8L (VIN 1) supercharged engine uses a similar lower intake manifold. The supercharger serves as the upper manifold.
    Lower Manifold

    NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold. Remove the upper intake manifold to service the lower intake.
    The 3.8L (VIN 1) supercharged engine uses a manifold similar to the 3.8L (VIN K), but the supercharger serves as the upper manifold.
    1. Disconnect the negative battery cable.
    2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
    3. Remove the upper intake manifold using the procedure above.
    4. Remove the EGR outlet pipe from the intake manifold.
    5. Detach the engine coolant temperature sensor wiring harness from the sensor.
    6. Remove the lower intake manifold bolts and carefully lift off the manifold.

    To install:


    0900c15280269f1b.jpg enlarge_icon.gifenlarge_tooltip.gif Fig. Lower intake manifold bolt torque sequence-3.8L (VIN K) engine
    1. Clean all parts well with degreaser, especially the gasket seal surfaces on the upper and lower manifold pieces and between the lower manifold and the cylinder heads..
    2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Apply thread-locking compound to the bolt threads. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 11 ft. lbs. (15 Nm). Follow the toque sequence, starting in the center, then working outwards in a circle.
    3. Install the remaining components in the reverse order of the removal process.

    Upper Intake Manifold (Plenum)
    1. Disconnect the negative battery cable.
    2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
    3. Tag for identification, then remove the right side spark plug wires.
    4. Disconnect the ignition wires from the fuel rail.
    5. Remove the fuel rail. Please see Section 5.
    6. Remove the cable bracket from the intake manifold.
    7. Remove the throttle body.


    NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold.
    1. Remove the upper intake manifold bolts and carefully lift the upper intake manifold from the engine.

    2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 89 inch lbs. (10 Nm). Follow the torque sequence, starting in the center, then working outwards in a circle.

    1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
    2. Properly relieve the fuel system pressure.
    3. Drain the coolant system.
    4. Remove or disconnect the following:
      • Negative battery cable
      • Air cleaner fresh air hose
      • Positive Crankcase Ventilation (PCV) valve hose
      • Fuel line from the rail
      • Throttle cable from the throttle body
      • Throttle cable bracket nuts
      • Fuel injector electrical connectors
      • Throttle Position (TP) sensor electrical connectors
      • Idle Air Control (IAC) valve electrical connectors
      • Manifold Absolute Pressure (MAP) sensor electrical connectors
      • Exhaust Gas Recirculation (EGR) valve electrical connectors
      • Heater hose from the intake manifold outlet
    5. Position the wiring harness over the brake master cylinder
    6. Remove or disconnect the following:
      • Intake manifold support bracket bolt
      • Label the vacuum line for proper assembly
      • Drive belt
      • Power steering pump
      • Upper intake manifold bolts
      • Evaporative Emissions (EVAP) canister purge valve solenoid vacuum hose
      • Brake booster vacuum hose
      • Lower intake manifold bolts
      • Intake manifold
      To install:
    7. Thoroughly clean all gasket mating surfaces. Be careful not to damage or score the aluminum surface. If replaced, use Loctite® 290, to seal the new PCV valve inlet tube into the manifold. NOTE: Refer to Section 1 of this manual for the intake manifold torque sequence illustration. The illustration is located after the Torque Specification Chart.
    8. Install or connect the following:
      • New gasket and manifold. Torque the nuts in sequence to 22 ft. lbs. (30 Nm).
      • Power steering pump. Torque the fasteners to 27 ft. lbs. (38 Nm).
      • Drive belt.
      • Heater hose and install the manifold support bracket bolt. Tighten the bolt to 22 ft. lbs. (30 Nm).
      • Lubricate the male ends of the fuel lines with a few drops of clean engine oil, then connect the fuel supply and return lines.
      • Fuel line(s) in the retaining bracket. Torque the mounting screw to 36 inch lbs. (4 Nm).
      • Throttle cable to the throttle body and attach the accelerator cable bracket. Torque the bolts to 22 ft. lbs. (30 Nm).
      • Reposition the wiring harness and connect the wiring and vacuum hoses to their original locations. The harness leads to the TP sensor and EGR solenoid must be routed between the intake manifold runners.
      • Negative battery cable
    9. Fill the coolant system.
    10. Prime the fuel system by cycling the ignition ON for 5 seconds and OFF for 10 seconds a few times without cranking the engine.
    11. Start the engine, check for leaks, and repair if necessary.
