Wow... never heard of one needing the IM but then I haven't seen your car or know whats up.

You will find it VERY difficult to locate other than dealers because it is whats known as a captive part (dealer only)

Are you UK or USA? I may be able to help

#3 CYLINDER IS FULL OF FEUL AND TRUCK WILL NOT START.REMOVED SPARK PLUGS AND GAS POURS ON GROUND WHEN KEY IS TURNED ON FROM #3 CYLINDER PLUG HOLE.


The Vortec engines were notorious for those kind of problems. The problem will be under the upper-intake manifold, and the fuel injector assembly will either have a cracked plastic fuel line running out to one or more of the fuel injectors, or the fuel pressure regulator that is located on the end of the fuel injector assembly is faulty or it has detached from the fuel injector assembly. Either way the lower intake manifold will be flooded with fuel anytime that the fuel pump runs.

There were two types made, the first type had fuel lines that connected to the lower intake manifold, and then from the metal fittings the fuel line turns into plastic and runs inside the lower intake manifold and under the upper-intake manifold where it runs over to the fuel injector assembly, and this type can really flood out an engine when it becomes faulty.

The second type had metal fuel lines running over the upper intake manifold and they connected to the top of the fuel injector assembly, however, under the upper-intake manifold there are still plastic lines to the fuel injectors and also the fuel pressure regulator that could be faulty and cause the engine to severely flood.

The upper-intake manifold is not that difficult to remove, and after you remove the upper-intake manifold then (replace the fuel lines to the fuel injector assembly if it is the second type) turn the ignition to the "Run" position and when the fuel pump runs you should see where the fuel is leaking/spraying from, and it will most likely be a large high pressure leak from a ruptured plastic fuel line.

Let me know if you require any further assistance.

Erratic idling in my landrover Freelander 1.8 1999 petrol. I have already attended to my Stepper motor and intake manifold. Now I am about to fit in a new water-pump. Does the latter have any direct effect...


look for a cracked in let maifold. spray liberal amounts all over . if engine runs faster then you may need to replace uless you can repair with epoxy.

I have 03 land rover freelander and the intake cam has broke at the timming gear twice now wondering if there is a common prob with this and a fix it is the v6 and its on the front bank


the cams are fragile too big a job to describe in full . bet it broke after cam belt change should never use power tools to undo cam pulley bolts all the bolts should be undone only when engine is locked with correct locking kit to avoid strees on cams new bolts should be fitted on re assembly to correct tourqe setting while cams are locked hope this helps you

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.

  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.

Ticking sound from engine


i doubt it is a lifter but it could be. they are of the hydralic type. it is probably one of the cheap plastic motors in the intake manifold. they always go out. a new manifold cost about 900 us.
