Ticking noise coming from manifold


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.

When I accelerate, there is a tin can kind of sound. The sound ceases when just cruising along. Only hear it on acceleration? Any tips of what that could be??Thanks!


Have a 1997 T100 SR5. 146,000 miles. Had the same problem. It's the heat shields over the exhaust manifolds. The welds break and they rattle. I used high-temperature exhaust putty and c-clamps to hold them steady. Works great. (Don't have access to a welder)

How do i change a water pump in a 97 grand am with a 2.4 litre engine


2.4L Engine
See Figure 3
  1. Disconnect the negative battery cable.
  2. Drain and recycle the engine coolant.
  3. Disconnect the oxygen sensor wiring.
  4. Remove the upper exhaust manifold heat shield.
  5. Raise and safely support the front end of the vehicle securely on jackstands.
  6. Remove the exhaust manifold brace bolt.
  7. Unbolt and remove the lower exhaust manifold heat shield.
  8. Break loose the manifold-to-exhaust pipe spring loaded nuts.
  9. Unbolt the radiator outlet pipe assembly from the water pump cover.
  10. Disconnect the exhaust pipe from the manifold.
  11. Pull down and back on the exhaust pipe to disengage it from the exhaust manifold bolts.
Do not rotate the flex coupling more than 4°. this could damage the component.
  1. Separate the radiator outlet pipe from the oil pan and transaxle.
    1. On manual transaxle, remove the exhaust manifold brace.

  2. Next, leave the lower radiator hose attached and pull down on the outlet pipe to detach it from the water pump. Allow the outlet pipe to hang.
  3. Lower the vehicle.
  4. Remove the exhaust manifold-to-cylinder head nuts.
  5. Extract the manifold, seals and gaskets.
  6. Remove the timing chain cover. Refer to the procedure later on in this section.
  7. Remove the timing chain tensioner. Refer to Timing Chain removal later in this section.
  8. Unbolt the water pump from the cylinder block.
  9. Extract the pump assembly-to-timing chain housing nuts.
  10. Remove the water pump and cover assembly.
  11. Separate the pump from the cover.
  12. Clean all mating surfaces of gaskets and sealant materials.

To install:
Prior to installing the water pump, read the entire procedure. Pay special attention to the tightening sequence to avoid component damage and ensure a proper seal.
  1. Attach the water pump to the cover and hand-tighten the components.
  2. Lubricate the splines of the water pump drive with chassis grease or equivalent, then install the pump and cover assembly. Hand tighten the cover-to-block bolts.
  3. Install the pump-to-chain housing nuts and hand-tighten.
  4. Lubricate the O-ring on the radiator outlet pipe with an anti-freeze solution and slide the pipe into the water pump cover, install and hand-tighten the bolts.
  5. With the specified gaps, tighten in sequence as follows:
    1. Pump assembly-to-chain housing nuts
    2. Pump cover-to-pump assembly
    3. Cover-to-block, bottom bolt first
    4. Radiator outlet pipe assembly-to-cover

  6. Install the exhaust manifold using new gaskets.
  7. Install the manifold-to-cylinder head nuts, follow the tightening sequence and tighten to specifications.
  8. Raise and support the front of the vehicle.
  9. Index the exhaust manifold-to-exhaust pipe flange bolts.
    1. Turn bolt bolts in evenly to avoid cocking the exhaust pipe and binding the bolts. Turn the bolts in until they are fully seated.

  10. Install and secure the radiator outlet pipe to the transaxle and oil pan.

On manual transaxles, install the exhaust manifold brace.
  1. Install the timing chain tensioner and chain cover.
  2. Attach the lower heat shield.
  3. Lower the vehicle.
  4. Attach the exhaust manifold brace. Tighten the manifold-to-exhaust pipe nuts to specification.
  5. Attach and secure the upper heat shield.
  6. Connect the oxygen sensor wiring.
  7. Fill the radiator with coolant water mixture until it reaches the heater hose coolant outlet, then install the hose and continue to fill. This will assist with the complete cylinder block fill.
  8. Connect the negative battery cable.
  9. Start the engine and top off the cooling system and check for leaks.

My 2005 Corolla XRS has rattling when deaccelerating


I wouldn't say it is common. There are quite a few heat shields around the stock exhaust "header" and exhaust system. There are also FOUR motor mounts that you can check to see if all bolts are tight. They are all 14mm heads on the motor mounts, 12mm on the exhaust shields. These seem to be the main things that may get loose or make a rattling sound. The exhaust gasket is also designed to flex when the engine flexes - I would check into the exhaust. You have to remove the TRD strut bar to gain better access from above.

My 1991 Saturn makes a rattling sound in the engine


This is more than likely the exhaust manifold heat shield. Check around the small bolts that hold the shield to the manifold. It usually cracks in a circle around the head of the bolt. Press on the top and bottom of the shield (WHEN COOL) and rock it. You will see where the shield is cracked. The shield is available as a service part, and is not expensive.

Accelarating from 25 to 40 MPH - a "rattle" in exhaust system


Had my y-pipe replaced (bad cats) and the bolts at the y-pipe flange where it attaches to the exhaust manifolds started to get loose and I go tthe viberating (tinning) noise. Took it in the first time and they tightened everything up but it seems it's doing it again so I'm going to try to fix on my own. Just wondering how much of a pain it's going to be to get to the bolts and what size...
