2010 Nissan 370z Weird Noise

Bigchillin · 06-14-2017, 11:40 PM

Hey all,

I have a 2010 370z TT and I'm experiencing weird noises when i accelerate roughly hard and uphill. It doesn't happen all the time either. It's weird to describe and isn't loud which is why I could not record it. It seems as if I ran over something and it kicked up into my wheel well. It is coming from the front driver side.

Maybe loose exhaust?

Thanks

That is not a lot to go on. piece of turbo piping hitting something under acceleration? OEM suspension parts? Could be any number of things.

is the sound more loud higher to rpm, or speed, or is it a constant sound under any amount of throttle

I need to hit the gas pretty hard while going uphill to hear it. It doesn't do it all the time.

Would the sound come through on a video?

Need a lot more info, is it a metallic noise? A thudding noise? Squealing? Does it sound like it's in the actual fender well itself, or the engine bay on that side? Closer to the cabin, or the nose of the car? Is it intermittent when it happens or constant? Is it French? Does it resemble the screeching roar of Godzilla in anyway?

From the info I have, I assume you ran over a small homeless child and kicked him up into your fenderwell, and when you put the motor under a lot of load the turbos get hotter and it pisses him off, so he's knocking to tell you it's getting too hot under there. Toss a few bottles of water and some chicken nuggets under there and you should be fine.

Probably not. I'll have to try, but when it happens it only does it for a second. It is not constant and the noise doesn't increase when I'm going faster etc. just sounds like I ran over something.

Bigchillin · 06-15-2017, 10:16 AM

Lmao sway nice one. It's more of a metallic noise coming from the driver side of the engine bay, or directly underneath my seat because when I have the windows down that is when I hear it the most. There is no squealing, it's just kind of a thump and then gone. It's definitely closer to the cabin itself rather than the nose of the car.

Are you sure the engine isn't knocking? I'd try running a tankful of the next octane level.

Chuck33079 · 06-15-2017, 10:24 AM

What's it look like underneath when you take the undertray off? Is there anything that's close enough to touch something else when the suspension is compressed?

Bigchillin · 06-15-2017, 10:24 AM

I run 93. I'm sure the engine isn't knocking because why would it only do it uphill?

Higher load going uphill.

I'm gonna put her on the lift Saturday and check it all out. Also going to do an oil change, maybe that'll help. Thanks guys

Do you have any suspension mods?

Also, it might be the engine flexing in a certain way when you are accelerating uphill.

Bigchillin · 06-15-2017, 11:50 AM

Nope, suspension is all stock.
