Question about 2004 Dodge Caravan

1 Answer

2000 Grand Voyager 3.3 Engine noise

The engine is producing a rattle, under load, only in the RPM range of 1500 - 2000. The noise is not a ticking, squealing or high pitched rub. It is as if ball bearings are rattling around or being shaken inside the motor. The noise mostly comes from behind the intake plenum.

The engine performs very well. Plenty of power, starts everytime and is getting 19-20 mpg around town. You can make the noise appear and disappear by going up a hill and feathering the gas to keep the van doing 2,000 RPM.

Any suggestions are greatly appreciated.

How do I fix an engine rattle at low rpm, light load, city speeds? The spark plugs aren't due for replacement yet, should I be going after an exhaust sensor?


Depends on your definition of rattle. Engines don't rattle unless something is loose or a rock has landed in a cooling hole on the side of the catalytic converter. So , if you can give us a better description of what the engine is doing, you'll get a load of incorrect answers.

F22a engine produces strange noise most obvious at 2000 rpm, what could the problem be?


Without a general description of what the noice sounds like, squeal as compared to knocking, it is impossible to help you. Engines make a lot of different noises, so try and help by describing noise. I would suspect it is belt related, or tension pulley related as these are RPM variable noises, belts tend to slip when you accelerate and can be quite loud with a serpentine belt as example.

Tapping/ticking noise when rpm goes above 2000 with check oil warning on my chevrolet lumina ls 2005 model


You will have to take an oil pressure reading and compare to specifications. It could be that the pick up screen is plugged. Do not drive the car as damage to engine will occur.

Knocking knoise under 1500 rpm


If your car has hydraulic tappets and low low oil pressure at engine speeds then it can make tapping noises. Oil pressure is needed to maintaine the tappets clearances, excessive cleaeances will produce noises.

Motor makes a pecking sound at 2000 rpm only under a load.does not do it while reving parked


Noise out of the engine. Noisy valves? Low oil level? Is the sound like tick, tick, tick, tick......that's how bad valves sound. I don't know if you have solid lifters those have to be adjusted after some mileage. Hydraulic ones are self adjusting. Only a good mechanic can tell for sure.

Car has no power and has a rattling noise


RPM and speed do not match what I'd expect to see at 120. but that could be gear ratio being different than I'd expect. Most don't like to run at 4k. Most problems at that rpm is either plugs (experiment with different gap settings or change heat range one step colder or hotter) or can be coil related (work fine except when recovery time is shortened due to rpm). However, the weird noise may be due to a partially plugged catalytic converter. So, check that as well. If you have a knock sensor, test that too.

2000pontiacgrandprix noise under accelration maybe exhuast?


Hello! First of all, congrats on owning a great car! That engine (3.8L Series II L67) is without a doubt one of the finest GM (Buick) has ever produced!

On to your problem - I think you have one of 2 things wrong:

1) a loose heat shield
2) a broken exhaust hanger

Both of these will cause intermittent (and highly annoying) rattling sounds, especially at low speeds or when the engine is under load (like going up a hill for instance). There are 2 hangers under the car located almost directly under the front floorboard. These are prone to breakage. There is also a heat shield in this same area - that is very prone to coming loose. If it's the heat shield - you can either remove it - or have it tack welded. If the hanger(s) are broken, you will need to take it to an exhaust shop (unless you know a welder :) ) and have those fixed - shouldn't cost you more than $20 either way.

Hope this helps and good luck!

Ticking noise in engine


May be mice, but I had a truck that did that from a worn speedo cable.
