There is more than 1 v8, I need liter size of engine?

On the 2.4 liter four-cylinder engine it is located on the siie of the engine block (the side nearest the firewall).

On the 3.0 Liter V-6 engine there are 2 knock sensors and the are located in the "valley" below the intake manifold. You'll have to remove the intake manifold to get to them.

Ticking noise coming from the manifold? There are two types of manifold....1. Instake manifold and exhaust manifold. Please indentify and apply as needed.

Intake manifold
1. Double check the nuts and bolts around the intake manifold if you worked on it and had it serviced.
2. Spark plugs loose. Yes!! I've seen this before and it comes the rear of the manifold..very confusing.
3. Check your valves and have them adjusted. (This will require a trained and qulified mechanic).
4. Check your motor oil and power steering pump fluid.

Exhaust manifold
1. Check for loose nuts and bolts.
2. Check the O2 sensors connections...some models have 2-3. They are the sensors sticking into the pipes.
3. Your catalytic converter may have a defect. If possible, remove it and shake it to determine failure. (I've seen and experienced the so called honeycomb inside it breakign apart.)
4. Check the exhaust manifold heat shield if applicable.

Hi thanks for your question' The electronic EGR valve and solenoid assembly is attached to the rear of the left cylinder head ,

1. Remove electrical connector (5) at top of EGR valve solenoid.
2. Remove tube mounting bolt (1) at intake manifold.

1. Remove two bolts (4) connecting EGR tube (1) to valve assembly.
2. Remove gasket located between EGR tube flange and EGR valve assembly.
3. Remove two EGR valve mounting bolts (5).
4. Separate valve assembly (3) from engine.
5. Remove and discard metal gasket located between cylinder head and valve assembly.

INSTALLATION

1. Clean area at rear of left cylinder head where it joins base of EGR valve.
2. Clean EGR tube where it joins EGR valve.
3. Position new gasket between EGR valve and cylinder head.
4. Position EGR valve to cylinder head. Install and tighten two bolts (5). Refer to Torque Specifications.
5. Position new gasket between EGR tube flange and EGR valve assembly.
6. Position EGR tube (1) to side of EGR valve and into intake manifold.
   1. Install EGR tube flange bolt (1) at intake manifold. Tighten bolt. Refer to Torque Specifications.
   2. Connect electrical connector (5) to top of EGR valve solenoid (2).Do a final tightening of two EGR tube bolts (4). Refer to Torque Specifications

Check the vacuum m rotaangueras like to check the hose connecting the air filter with the intake manifold is broken and that if the airflowmeter not work ...

hopefully an intake manifold leak and not a bad head gasket or cracked head

hi you try unbolting the manifold from the exhaust joint it will make the head heavy but much easier to remove in one hope that helps

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.

its in the engine compartment next to the battery in a black plastic case. It is about 8 inches long 2 inches wide and 2 inches high.
