I will do it tomorrow morning.SnowItch said:It's truly amazing what the human mind can block out. Once you do the research and convince yourself that something isn't a problem, poof, you won't hear it anymore.
It will be interesting to hear it if you can pick it up. But even if you do, there are so many variables (inside, outside, the microphone, clear day, cloudy day, open field, trees all around) that can affect the acoustics that it won't really provide an accurate comparison.[/color]
My old next door neighbor had all sorts of audio equipment that he would be able to set up some type of measuring device and tell me if my engine had changed its noise over time (he used to engine tracking the week by week progress of an engine breaking in).
Another case were it would be interesting to pick the brains of one of the engineers and see what level of knocking was considered "acceptable"
I can hear our V6 tapping away happily when it's idling. Only when I'm outside of the vehicle though, I can't hear it from the inside.SnowItch said:I have never heard it. I have been told, that it does occur (a natural result of the Direct Injection), but because the engine/valves/cylinders are different sizes, the resulting "tapping" is at a different amplitude/tone/volume so that it is not noticeable.
Having said that, and having a sister who has perfect pitch, my guess is that she would hear it (she hears lots of things no one else can).
My thoughts and experience exactly.GMCdriver said:I noticed the tapping noise on my V6 the first time I used my remote starter and was very concerned untill I found out that it was caused by the high pressure levels of the direct injection and not by problimatic valves like I first thought.
I only notice it at idle and only from outside the vehicle, I've never noticed it from inside the cabin.
No worries there, Roesterman, but thanks just the same!Roesterman said:Just so you know you aren't crazy[/color], I can hear the loud "tapping"... almost diesel like(from the sound clip)
