SOURCE: Fill drill and tap aluminum manifold

Using a torch of any kind will be extremely difficult for filling a stub hole. Even trying to tig it would be quite a challenge. If you can get it clean enough," PC-7" or "All-Metal" filler putty will work. The metal MUST be totally grease & oil free. Use carbutator cleaner or some other good grease cutter and a small round brush. Pipe cleaners with stiff bristles work well. Use a pin or small pick to reach into the remaining threads to break up any solids. Work the filler into the threads and push a hard aluminum rod into the hole. The rod must be sliightly scored for the filler to grab on to it. Give it a full 24 hours to cure. Sand it flat, center punch, drill & tap. The new hole will be as good if not stronger than the origiinal. About 2 hours, not including the cure time.

SOURCE: lower intake manifold gasket leaking 02 Olds Silhouette

This is basicly a very time consuming job rather than a physically hard one to complete. In order to replace the gasket you must remove the intake plenum,throttle body, and misc. vacuum hoses. The wiring harness connections must also be disconnected. Finally the intake manifold is exposed. The bolts holding the manifold to the block are removed exposing the leaking gasket. After removing the push rods and placing them in the correct order to be replaced the gasket and sealants can be removed. Finally replace everything in reverse order. Be sure to consult a GM manual for correct bolt torch specs. The correct specs for the manifold bolts usually come with the gasket. Make sure to change your oil a few times after this job in case any coolant entered the block. Also,change the thermostat and the oil seal on the distributor half shaft cap while you have everything off. Good Luck

SOURCE: need head bolt,intake upper and lower and rocker arm torque lbs.

Head bolts--------- 22 ft lbs.
Intake upper------ 18 ft lbs.
Intake lower------- 10 ft lbs. Tighten vertical bolts first, the diagonal bolts, failure to do this will result in an oil leak.
As far as the rocker arm bolts, they have to be adjusted with the valves closed, tighten down just enough to turn the push rods with your fingers with slight tension.
This is out of a Technical Specifications Manual.

What do the intake manifold bolts for a 2002 Chevy Malibu with a 3.1L need to be torqued to?
Pretend the picture is lower intake manifold, that is the tightening sequence.
1st step 5 ft lbs
2nd step bolts 1--4 9.6 ft lbs
3rd step bolts 5--8 18 ft lbs
The upper intake manifold use about the same sequence tighten to 18 ft lbs.
If you don't like ft lbs use inch lbs.
If the upper intake manifold is plastic, be careful with that.

Torque sequence for 1996 chevrolet van intake manifold with a 4.3 litre moter
Ha, you tried to fool me with the bit about a 3.5 L motor--I could find that one...here is the complete procedure from AutoZone.com:




Installation To install:
  1. Clean the gasket mounting surfaces. Be sure to inspect the manifold for warpage and/or cracks. If necessary, replace it.
  2. Position the gaskets on the cylinder head with the port blocking plates to the rear and the This Side Up stamps facing upward. Then apply a 3 / 16 in. (5mm) bead of RTV sealant on the front and rear of the engine block at the block-to-manifold mating surface. Extend the bead 1 / 2 in. (13mm) up each cylinder head to seal and retain the gaskets.

  3. Install the lower intake manifold. Tighten the bolts in sequence and in 3 steps, as follows:


    1. Step 1: 26 inch lbs. (3 Nm).
    2. Step 2: 106 inch lbs. (12 Nm).
    3. Step 3: 133 inch. lbs. (15 Nm).

  4. Install or connect the following:

  5. Install transmission oil dipstick tube, if necessary.

    Fuel supply and return lines to the rear of the lower intake
  6. Temporarily reattach the negative battery cable, then pressurize the fuel system (by cycling the ignition without starting the engine) and check for leaks.
  7. Disconnect the negative battery cable.
  8. Install or connect the following:

    Heater hose to the lower intake Upper radiator hose to the thermostat housing Distributor assembly and engage the wiring Ignition coil Connect vacuum hoses to the upper and lower intake manifold. New upper intake manifold gasket, making sure the green sealing lines are facing upward Upper intake manifold Manifold retainers. Tighten them to 88 inch lbs. (10 Nm) using two passes.

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.
