2001 jaguar 4.0 supercharged have water in left bank isolated to rear cyl wondering if this is possible supercharger failure or head gasket/head failure?

Transmission Control Module (TCM) (LS4)
Left front of the engine compartment, near the left headlight assembly .What engine does your vehicle have ?

LS4
Engine - Gas, 8 CYL, 5.3L, SFI, Aluminum, Cylinder Deactivation, GM

I'm going to take a wild guess an say you have 3.8l

L32
Engine - Gas, 6 Cylinder, 3.8L, SFI, V6 L32
Engine - Gas, 6 Cylinder, 3.8L, SFI, V6 Supercharged, GM
, GM

If it's the 3.8l L32
Engine - Gas, 6 Cylinder, 3.8L, SFI, V6 Supercharged, GM you don't have a TCM module . you have the PCM

p0306 is misfire with number 6 cylinder P0306 Cylinder 6 Misfire Detected and p1314 cat converter problem P1314 Misfire Rate Catalyst Damage Fault Bank 2 P1314

I don't know the definite answer to your question but water pumps are generally better at pushing water than sucking it so as a general rule I would expect to find the pump the first item in the circuit.

I hope this helps...

Replace the transmission gasket and rear engine seal. Might check out turbo gaskets too.

Start out at least $1500. Depends on what has to be done to the heads. If you have a cracked head, easily add $500 to that price.

an axle problem will not increase the rpm so that is eliminated
supercharger will not make the engine rpm higher between gears so that is eliminated also
indicates a transmission problem not selecting the next ratio at the correct rpm and road speed
possible needs a transmission fluid change , clutch and band adjustment
have the fault codes read to check for faulty TR sensor or TCM failure

facing the car from the front it should be at the left hand side at the rear, take fire wall shelf off for an easier access.

Hi!!

This instruccions are for supercharged and non supercharged engines, if your engine is not supercharged disgreggard steps 4 and 8
.
To replace the alternator, remove or disconnect the following:

1 Negative battery cable 2. Air intake assembly 3. Cooling fan assembly 4. Supercharger drive belt, if equipped 5. Accessory drive belt 6. Alternator air intake ducting 7. Alternator wiring connectors 8. Supercharger water pump, if equipped 9. Alternator Good Luck!! Don't forget to rate this post!!

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:


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.

To install:

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.
