Engine noise
 

Notice this noise after driving for a while. Is it normal sound? I can't reproduce the noise when cold start, then rev to 3000 rpm a few times. The noise only happens after driving for a while.

Sound very normal to me. Just sounds like the valvetrain doing it's thing.

It does sound a little bit louder than normal, but not anything to really worry about imo. Sound is so subjective on the internet. What oil are you running? A slightly heavier oil might quiet it down a little bit. The injectors make a little bit of noise too.

thats how mine sound like too ,,i think its normal

Mine sounds like a garbage disposal after long periods of driving. Usually when it's warmer out and after about 1.5 hours of driving.

No one's is louder than mine. :(

^hahaha no seriously you only hear it after driving because the rpms are down low enough and it has solid valvetrain and loud injectors.

You guys aint heard nothing yet..

Yes, that is a normal sound.

This shows you how loud a mechanical car can be at idle be happy the z's are as quiet as they are.

jsolo u should throw that in the oem clutch noise thread.

Got a link for said thread?

Edit... I think i found it.

sounds like injector to me...imho

If it is the injector, should it be that loud? And why only hear one injector making the noise. Will take to the dealer next month. Thanks
