high pitched noise (like mosqito sound) from engine

Limeybastard · 07-08-2014, 07:30 AM

Funny when I bought mine I heard a whine after shutting engine down from the engine bay area. It only occured once so far.

Probably the fuel pump.

So many mosquitoes in FL that's all I hear outdoors....Live music and age prevent me from hearing that noise, haha.

Thank you gentlemen, I do indeed have FI HFCs on the car.

I have a 2010 and it whines all the time (electrical sounding). You can hear it when the stereo is off and when you turn the car off. I think it's mostly the fuel pump when car is off cause it's louder than at start up. I haven't had any issues and the car is pushing 34K. I've gotten use to it and don't notice it because of boost and my exhaust system!

I agree its really hard to notice anything with all that turbo whistle going on

I have a Nissan X-terra that has a 3.5 litre engine. I believe it's the same engine they put in the 350Z. At about 20k miles it started to whine as the engine RPM increased. You could actually hear it go up and down with the RPMs. One of my friends said it sounded like it was coming from the front of the engine. Turns out the timing chain guides were defective and had to be replaced. There was a TSB put out by NIssan, but car owners weren't informed. I was told it didn't affect enough owners. They reapired it under warranty.

Alright, I have now heard the whine noise in my cabin, it took me a while to separate it from my bad tinnitus!

Okay.. here is an update. I went to my Nissan dealership about 2 weeks ago and tech stated my manual transmission need to be replaced.. Part has been ordered yesterday and yes, it's being covered under warranty. It took 2 weeks to Nissan Warranty Dpet to approve lol. My technician had to fight back and forth with them.

The bad news is Nissan does not provide rental cars and my insurance won't provide rental cars cuz it's not caused from accident lol wtf.. I kinda need to fight this with my insurance compaby..

Thought the noise was from engine but it's actually from trasmission LMAO I must be deaf
