Just bought my car NEW 06, now it has 650+ miles and when I rev over 6.5K or so, i get a metallic krr krr krrr noise, similar to marbles in a blender thingy i think. There is no loss in power or anything just that it makes that noise

Got an appointment with the dealer on Saturday, so we'll see. Hope its not too serius meaning engine needing replacing etc.

Do you use premium gas?

Thought I would ask.

Unhooked

yep premium 93 from day one, researching this problem as we speak

Nopstnz

Make sure when you are revving to that the engine temp is cold.

did a search for SDAIS and not much came up. Where is the thread that you talk abt?


This happend when the engine was warm.

I just want to know if the noise is normal and if it why did it just start happening? I am thinking it maybe the heating/cooling system.

Also dumb question what does WOT stand for?

WOT = wide open throttle

As to whether it's normal or at least harmless, well, that's something that a few of us would want to know too. There are two threads on the subject, one in this forum and another in the Tech Garage.

WOT = Wide Open Throttle

Look up the guys near you, would be much more valuable usage of time. Hard to say what it is through electronic text.

It's a normal sound

LionZoo

It could very well be, but it doesn't seem like everyone gets it (including some guys that push their cars) and that is a bit concerning. Also the service writer at my (now) local dealer called it ping when I described it over the phone and this guy came highly recommended by a couple people in the Bay Area. Supposedly the new flash will address it, we'll see...

Stavesacre21

you could stop about right there

lack of an engine break-in could very well be the case. Lets hope not though, cause that means it won't be a cheap fix. Also as a bonus, it's not proven but some people say that engines which aren't broke in properly sustain worse gas mileage.

How long you been revving your NEW car over 6.5K? From what i've heard, running over even 4-6K until 1500-2000 miles isn't recommended...

LionZoo

That's debatable. Some people on this board (including a certain rotary deity) swear by the hard break-in method. The Mazda manual itself only recommends keeping it below 7,000 rpms for the first 600 miles.

650 miles? your car isn't even fully broken in yet.... just wait until its fully broken in and then see what happens..... I had some small noises too, but after 800 miles it all went away....

Stavesacre21

hence why i said it's not proven.

heck, my dealer told me that break-in's are a thing of the past, and that the 8 doesn't even have one

don't believe everything you hear. And yes, break-in IS debatable, but this was just a POSSIBILITY. I never stated it to be the law.

Let us know what the dealer tells you.

I think I have the exact sound you're getting. I think marbles in a blender is a totally different sound than what you're getting. You said "Krr Krr" like a high frequency metallic sound. Marbles in a blender would sound like "tata tata tata" very fast.

And yes, the sound in my car does come from somewhere on the dash. Sometimes it sounds like its coming from the rear-view mirror, other times it sounds like its coming from the vents just in front of the windsheild.

The thing is is that I can hear the sound regardless of RPM. If I go over a rough patch of road I'll hear it.

24000 here and it's still here.

This is fucked up. This is like the 5th ******* thread in the past few months and nobody knows where the marbles are coming from.

I am thankful for Mazda for creating the rx8, but at least attend to the car's problems.

Raptor2k

There are several threads my friend.

And to repeat myself, like the original poster, I get the marbles fully warmed up, at around 7300 RPMS, they go away at about 8000, I've always used 93 octane. The sound began at around 15000 miles. Dealership is clueless and says it's normal.

tiggerlee

hmmm, 12,000 miles and no marble sounds......as a matter of fact I don't experience about 98% of the problems I read about here.
