Intake Gasket DIY questions.
So, I have noticed that I'm losing coolant, but I have NO outside evidence of leaking coolant, and I'm not overheating. From everything I read, it says to replace the intake gasket. If that's true, is the following procedure correct, or is there some steps that can be skipped?
Any other suggestions to do this job right, besides hiring a professional to do it?
To install:
Any other suggestions to do this job right, besides hiring a professional to do it?
- Remove the upper intake manifold using the recommended procedure outlined in this section.
- Remove the distributor.
- Disconnect the upper radiator hose from the thermostat housing.
- Disconnect the heater hose from the lower intake manifold.
- Remove the coolant by-pass hose.
- Remove the EGR valve.
- Disconnect the fuel pressure and return lines from the lower intake manifold.
- Disconnect the wiring harnesses and brackets from the lower manifold.
- Disconnect the throttle cable, the cruise control cable (if equipped) and the bracket from the manifold.
- If necessary, remove the left side valve cover.
- Remove the transmission oil level indicator and tube, if equipped.
- Remove the EGR tube, clamp and bolt.
- Remove the PCV valve and vacuum hoses.
- Remove the A/C compressor and bracket, but do NOT disconnect the lines. Move the compressor out of the way. Take care not to kink the A/C lines.
- Loosen the compressor mounting bracket and slide it forward, but do NOT remove it.
- Remove the power brake vacuum tube.
- If necessary, remove the alternator rear bracket bolt.
- Remove the lower intake manifold bolts.
- Remove the lower intake manifold.
To install:
- Clean all gasket surfaces completely.
- Install the intake manifold gaskets with the port blocking plates facing the rear. Factory gaskets should have the words "This Side Up" visible.
- Apply gasket sealer to the front and rear sealing surfaces of the engine block.
- Apply a 0.197 inch (5mm) bead of RTV sealer to the front and rear of the block. Extend the sealer approximately <sup>1</sup> / <sub>2</sub> -inch (13mm) onto the heads.
- Install the lower intake manifold.
- Apply sealer to the lower intake manifold bolts prior to installation.
- Install the bolts and tighten in sequence and in 3 steps as follows:
- First step to 71 inch lbs. (8 Nm).
- Second step to 106 inch lbs. (12 Nm).
- Final step to 11 ft. lbs. (15 Nm).
- Connect the wiring harnesses and brackets to the lower manifold.
- Install the power brake vacuum tube.
- Install the PCV valve and hose.
- Install the EGR tube, clamp and bolt.
- Install the transmission oil level indicator and tube, if equipped.
- If removed, install the left side valve cover.
- Connect the fuel pressure and return lines to the lower intake manifold.
- Connect the wiring harnesses and brackets to the lower manifold.
- Install the throttle cable bracket, then attach the throttle cable and the cruise control cable (if equipped).
- Install the EGR valve.
- Install the coolant by-pass hose.
- Connect the heater hose to the lower intake manifold.
- Connect the upper radiator hose to the thermostat housing.
- If removed, install the alternator bracket bolt.
- Install the A/C compressor and bracket.
- Install the distributor.
- Connect the negative battery cable.
- Refill the cooling system.
- Start the vehicle and check the ignition timing (not adjustable).
- Verify no oil, coolant, vacuum or fuel leaks.

that's bout right. make sure you mark distributor and get it back in exactly the same. just did head gaskets on my 'hoe, got it in a tooth off, had to redo it. hardest part about gaskets is just gettin to them. you can also leave the upper plenum on, just move wires and such out of the way, pull entire intake off as one. saves a few steps.

Which is the best intake gasket to use? I've been told about one that has some kind of metal inserts?
Are there special tools needed? Obviously socket set, and I'm assuming torque wrench, and anything else (besides band-aids)
