It's not that bad at all. After you remove the three bolts for the power steering pump and the two bolts for the drive belt tensioner it is sitting right in front of you.

Observe all applicable safety precautions when working around fuel. Whenever servicing the fuel system, always work in a well ventilated area. Do not allow fuel spray or vapors to come in contact with a spark or open flame. Keep a dry chemical fire extinguisher near the work area. Always keep fuel in a container specifically designed for fuel storage; also, always properly seal fuel containers to avoid the possibility of fire or explosion. LEFT SIDE (FRONT)

This is the entire task for it. It sounds like you might not have torqued it correctly, or your intake is cracked. But take a look at all of the info:

VIN K Engine On these engines, the upper and lower intake manifolds must be removed separately.
  1. Properly relieve the fuel system pressure, as outlined in Section 5 of this manual.
  2. Disconnect the negative battery cable.
  3. Drain the cooling system into a suitable container.
  4. Remove the fuel injector sight shield and air intake duct.
  5. Tag and disconnect the spark plug wires on the right side of the engine and position aside.
  6. Remove the manifold vacuum source.
  7. Remove the fuel rail.
  8. Remove the EGR heat shield.
  9. Unfasten the cable bracket-to-cylinder head mounting bolt.
  10. Disconnect the throttle cable.
  11. Remove the throttle body support bracket.
  12. Unfasten the upper intake manifold bolts, then remove the upper manifold.
This engine has two bolts which are hidden beneath the upper intake. These bolts are located in the right front and left rear corners of the lower intake manifold. This is why it is necessary to remove the upper before servicing the lower manifold.
  1. Disconnect the upper radiator hose.
  2. Remove the alternator, as outlined in Section 2 of this manual.
  3. Remove the drive belt tensioner.
  4. Remove the EGR valve outlet pipe.
  5. Unfasten the intake manifold bolt, then remove the manifold from the vehicle. Remove and discard the gaskets. Thoroughly clean the gasket mating surfaces, intake manifold bolts and bolt holes.
To install:
  1. Position a new gasket, then place the lower intake manifold over it. Apply a suitable threadlocking compound to the bolts, then install them. For 1995 vehicles, tighten the bolts twice, to 88 inch lbs. (10 Nm), in the sequence shown in the accompanying figure. For 1996-97 vehicles, tighten the bolts to 11 ft. lbs. (15 Nm), in the sequence shown in the accompanying figure.
    1. Install the EGR valve outlet pipe.
    2. Install the drive belt tensioner.
    3. Install the alternator.
    4. Connect the upper radiator hose.
    5. Position the upper intake manifold on the lower manifold. Install the retaining bolts and tighten to 89 inch lbs. (10 Nm).
    6. Install the throttle body support bracket, then connect the throttle cable.
    7. Install the cable bracket-to-cylinder head mounting bolt.
    8. Install the EGR heat shield.
    9. Install the fuel rail.
    10. Install the manifold vacuum source.
    11. Connect the right side spark wires on the right side of the engine.
    12. Install the fuel injector sight shield and air intake duct.
    13. Fill the cooling system with the proper type and amount of fluid.
    14. Connect the negative battery cable. Start the engine and check for leaks. Check the cooling system, and add as necessary.

Hot do you take off a 98 GMC 5.7 vortec intake


Note, removing the upper intake manifold is not necessary when removing lower intake manifold, they are removed as an assembly.
Disconnect negative battery cable. Drain cooling system. Remove air cleaner assembly and inlet duct. Mark and remove distributor. Remove upper radiator hose at thermostat housing. Disconnect accelerator and cruise control cables. Remove heater hoses from intake manifold. Remove EGR pipe.
Disconnect fuel lines at rear of engine. Remove AC compressor and set aside(leave hoses connected). Remove canister purge solenoid. Disconnect theSCPI injector, ignition coil, Ignition Control Module, generator,IAC motor, TP sensor, O2 sensor, Exhaust Gas Recirculation valve and Engine Coolant Temperature sensor wiring harness connectors. Remove PCV valve and hose. Remove lower intake manifold bolts. Remove lower intake manifold.
Installation.
Always use New O-rings when reconnecting fuel lines at rear of engine. Apply a bead of RTV silicone sealer along the front and rear sealing surfaces of the block.See Fig.6. Install new gaskets and intake manifold on block while RTV is still wet to the touch. Use Threadlock 12345382 or equivalent to lower intake manifold bolts. Tighten lower intake manifold bolts in sequence to specification table. See fig. 7. To complete installation, reverse removal procedure.f52665d.gifabc2b5f.gif

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:

  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.

To install:
  1. Clean all parts well with degreaser, especially the gasket seal surfaces on the upper and lower manifold pieces.
  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.
  3. Install the remaining components in the reverse order of the removal process.
