No. Removal of the intake manifold is not an attractive option.
...That will cost you more time and money in the long run.
You will need to replace the intake manifold gasket, and several others.

SOURCE: 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.

  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.

Why does EFI3 fuse keep blowing in a 2001 RAV4?


I had the exact same problem this week!

Turned out to be a shorted wire that feeds the lower oxygen sensor on the passenger side. The short was within the wiring harness that's buried under the intake manifold. Removing the intake manifold is a big hassle, as you can see here: Remove Intake Manifold To Find Leaking Head Gasket Toyota Rav4.

So to get quickly back on the road for the time being, I ended up just bypassing that section of the wire with a new length of wire, routed up & around the engine on the firewall. You can watch the video on the problem and repair here:

Just pulled the intake manifold on my BBC and found antifreeze in all of the closed intake valves, what caused that??


Not sure what engine you are speaking of, (other than BBC) but if you did not drain your cooling system before removing the intake manifold, any coolant in the manifold distribution channels would pour out through the easiest path once the gasket seal was broken.

I need a diagram to get the starter out of my 1998 Ford Escort.


Your starter is located on the back side of the engine at the top of the transmission bell housing, under the intake manifold. You can reach the main battery wire, and switch wire, by reaching from the right hand side under the intake manifold, the starter mounting bolts can be accessed by removing the air intake hose. Hope this helps, let me know.

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

I have a 1998 Ford Explorer with a 4.0 engine and a SOHC. I need to replace the thermastat housing. Is there to replace it without having to remove the intake manifold.


Yes. You should be able to replace it without removing the intake manifold. The bolts are very hard to reach, but it can be done with the proper set of sockets and universal joint extensions. I know it looks impossible. If in doubt, take it to a reputable repair shop. Don't let anybody charge you for intake manifold removal.

1998 kia sephia starter


Its located just under the intake manifold. you will need to remove the exhaust pipe to access it. there is also an upper and lower intake manifold support bracket that will need to be removed as well to extract the starter.

Its in a tough spot.
