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.

  3. Install the remaining components in the reverse order of the removal process.

SOURCE: Need to remove and replace the intake manifold

it is a great deal of work. The molded gaskets breakdown with time. You'll want to change the two 90 degree elbows as well - they are available from a dealer for a reasonable price. Also, the blower gasket is likely shrunk up and /or blown out. And you might as well replace the valve cover gaskets too as they leak oil as they breakdown with heat and time.

I did all of this on mine. Even as a professional, it took me a good 6 hours.

What can cause water to enter valve on 2003 buick century.


The manifold gasket failure was likely where the water went astray. Did any get down into the crankcase? You need to flush it all out. At some point, you will want to crank the engine over with all spark plugs removed to see if any more water spits out. I don't understand what manifold cover you mean had the cracks. If it is the manifold itself, you probably need another manifold, especially if it is a sealing surface. The lower intake manifold gasket is a common failure on GM V6's of these years. Good thing you caught it in time before it ruined the engine.

2003 Buick rendezvous oil in rthe coolant and vise vera


speculation is all I have, but it could be a cracked block, or a warped head/block mating surface. It happens when overheating.
I'm not an expert on the engine, but I know there were lots of problems with those getting oil/coolant mixing. If you ever get it fixed, keep 60-65% dexcool, not 50/50. seems to help prevent.

Temp gauge only goes to a 1/4 of the way up. does not heat up


Because its real hard to gert to. Most likely the throttle body needs to be removed and maybe part of the exh crossover. Check if the INTAKE MANIFOLD GASKETS are leaking. If they are have them replaced and the thermostat at the same time. Intake gaskets are REAL COMMON. Once the intake is off, its a 5 minute job.
