When accelerating hard, there is a clicking noise coming from my engine compartment. It sounds like tin hitting against something repetitively, though I do not thing it is a tin part. Any idea what might be?

 

Knock? It's really hard to know unless one hears it for him self. What octane gas do you use?

 

Typically I use 97 (I think). The noise is so hard to describe, but I hear cars making the same noise all the time. Right when I hit the gas it clicks several times then stops. I wish I could describe it better!

 

loose firewall or y-pipe....i have the same noise.....

 

Can this be fixed? I have it on my Maxima. Every time I mention it to the dealer, they look at me like I'm from Mars and just say "cannot duplicate"...

 

i have a 2k i30t and when accelerating similar noise, as you described, comes from my engine.
Not all the time though.

I hope it's nothing serious.

About a week ago I drove a 2002 Maxima and I heard a very similar noise from the engine of that car when I drove.

So what is the consensus can this be fixed, will it damage my car? The noise makes me nervous to accelerate, and I just have to drive fast! The noise is almost impossible to duplicate when I take it to the dealer. I need to fix this!

 

Any suggestions?

 

It's your engine knocking, mine does it too, and this is beginning to bother me. It goes and comes, even though I drive it pretty much the same and always fill with 91 shell. I spoke with my mechanic and he said he would take a look at it and run it for a while, but apparently a bunch of differently things can cause it. Because of that, and the positive stuff I have read about switching to synthetic oil in our cars, I will probably try that first, and let you guys know my experience with that.

 

Yes, please let me know how that works out for you. I am taking my car to Infiniti next week.
