I have this noise in my car almost all the time the engine is on (idling or not). I can hear it more in the night when it’s more quiet
Appreciate if you can tell me what is that? Is it urgent to get it repaired?
I have this noise for almost 1 year
It’s Pontiac Wave 2007 (like Chevrolet Aveo) with 92,000 km
My lame home computer won’t run videos or audios . I wonder if anybody who’s run them can describe the noise a bit.
Is it an external sounding noise, like pulleys/belts/heat shields?
Is it an internal sounding engine noise?
Can’t tell?
One should always be sure the engine oil is fresh, the proper specification, and up to proper level. If the noise started after an oil change and an aftermarket filter was installed, I’d suspect it as a culprit and install an Original Equipment filter. CSA
Thanks a lot for your comments. I indeed opened the hood but couldn’t see anything abnormal.
I changed the oil twice so it’s not after changing oil , but maybe the oil filter since it was not replaced recently with the oil change.
Can it be the timing belt noise or water pump noise??
I hope it’s exhaust vibration.
I’ll try to do more investigation.
Please let me know if you have more comments.
With the hood up, start the car cold, then CAREFULLY feel around the front (belt end) of the motor and see if you feel a rapping through the metal corresponding with the noise (which is pretty awful, by the way).
I’ve heard that sort of “rain on a metal roof” sound one time on my truck. It was a pretty severe case of engine pinging. I had just completed a repair and reversed a couple of vacuum hoses by mistake, and full vacuum was going to the advance control on the distributor. So I was getting something like 25 degrees advance at idle when the base timing should be around 6 BTDC. It made quite a racket, I must say. If anything that might have changed the ignition timing was done recently, consider pinging as a possible cause.
