Question about 1997 Cadillac DeVille

1 Answer

When engine is hot, if I accelerate too fast to pass, a very loud noise begins, almost like a motorcyle being revved. This goes on for a few seconds then stops. The engine does not seem to lose power or anything when this occurs. What could it be?

Check the resonator on the exhaust to see if it has come apart on the inside,also the fan clutch,and pulleys need to be inspected to see that the noise is not there.

2004 turbo desiel hilux Kzn 165 noise in engine when under load noise going at around 2000 rpm.


very possible that the noise is combustion ( piston slap) before the required time from a faulty injector that is passing fuel uncontrolled
at lower rpms it is a problem but at higher rpms the fuel being passed may be the required amount or the engine is revving to fast to hear it
I would suggest that you take it to an accredited diesel pump shop for a proper diagnosis , quote and have the injectors serviced

When I speed up to pass on freeway; 2x when I sped up from a red light, my titan revved but barley accelerated; engine not missing;trani not slipping when driving; no noises any suggestions?


Automatic I presume? While you claim the transmission is not slipping, the symptoms seem to point in that direction. The "punch" it, increases the load on the transmission. This behavior also points to drive line (transmission problems. It may be too late, but professional service may save the transmission.

Clunking/ticking noise during acceleration in 3rd and 4th gears


This sounds on the base of it to be pre ignition, if so the moment you take the foot off the gas it goes? The cure is to retard the ignition timing slightly, have you recently changed your octane of fuel? this will also cause this?
The noise is caused by the expansion of the compressed gases expanding before the piston reaches top dead centre causing the piston to \'rattle\' left unchecked will cause permanent damage and engine failure

I have a 1998 Cavalier (147,000 miles) that has made a ticking noise when I start it. However, revving the engine will quiet the noise before driving. Recently, it began making a extremely loud grinding...


unfortunately at 140,000 miles much like humans parts start to wear... now you can try to flush the oil system...I DON"T RECOMMEND IT.... I have seen engines tear apart from engine oil flushes.... drain refill the oil/filter with new oil and an additive may help, or pin down the noise to what lifter is going south and have it replaced... may end up being a very expensive repair depending on what they find when they open the engine up with high mileage...or just continue driving it untill it completely wipes out... I do belive its a hydraulic lifter that is not pumping up causing the tick and if so they usually last a long long time noisey.

Growling engine noise only at idle. Cam area


Take all of the belts off for a short run at idle. If the sound goes away it is pulley related, spin each pulley and listen for bearing noise, also check for play at this time.

If the noise does not go away when the motor is driving no accessories you have a more serious problem.

1997 s10 2 wheel drive truck. 4.3L v6 makes a loud noise as the car accelerates fast or under load. When running 55 I can release the gas pedal and the noise is not audible. I can put the truck in neutral...


Your noise sounds like it is power train related,If you have eliminated the engine,Since it doesn't make the noise while moving and in neutral.
It sounds like a universal joint in the drive shaft.Do you notice a vibration
along with the noise?

Loud air intake engine noise on startup


I would guess it is the electronic fan clutch. It will cause the fan to run too fast (very loud) and the light will come on sometimes.
