List of Different Marbles

My car came new from the dealership two weeks ago with 36 miles on the odo. I was assured that all recall related work had been attended to, but I don't have any formal detail regarding that from the dealership. My car and I are in NM now and my dealership in St.Louis. I am going to double check with them before heading home for the holidays, but this particular dealership has a decent history from a technical perspective with a service manager and team that have been in place many years. Hopefully they will be able to confirm the recall work again after I discuss my issues over the past weekend.

If it were normal, why is the RX-8 the only car that has these sounds (while most of the sounds aren't rotary-related)?
Marbles haven't blown up anything. Even when there's power loss.
We won't give it a rest because it ruins the rotary experience and we've payed a good amount of green to buy our cars, and we didn't expect these random sounds.
Gas mileage is the wrong analogy - anyone who did a little reading before buying the car should of had the expectation of having poor gas mileage, especially from a sports car. Also, gas mileage varies in most cases, you can have 10 mpg on one tank and 20 on the next.
This is rx8club.com, and people will continue to discuss problems with their car whether you like it or not.

No marbles except
Back when the rodent got into the air conditioner, turning on the fan did indeed cause a marble sound - removing the acorn from the fan chamber took care of the problem!

In case you didn't bother to read the point of this thread, it's to document the different marble sounds so that people have a convenient reference in case they get the sound. Since you're so tuned into complaining, I'm sure you know that just about every week someone starts a new marbles thread; this is a direct response of trying to stop that trend, but hey what do I know, I'm just complaining. You might also have noticed that I pop up a lot on the marble threads telling people that the heater core sound (which is what I have) won't do their engine any damage, that it's just a sound. Then again, I'm just complaining and worrying that my engine is going to explode right? Lastly, though some (not all) of the marbles are not real problems, they do detract from the experience, and anything can be improved. Just because it's not a real problem doesn't mean Mazda can't make it better. After all, there's nothing fundamentally wrong with a tire from the 1980s, but the tire manufacturers seemed fit to believe that they still needed to improve.

Momentum Keeps Me Going
I had marbles with my '72 RX-2 and marbles with my '04 Rx-8...sometimes... usually under light load at mid-RPMs. Not all the time, but only sometimes. Big deal. It's a rotary thing. I've simply tuned it out if it is there anymore. The 8 has no major problems whatsoever as a result of this noise.
But here's a sure cure. I can tell you, for what it's worth, that in 6 hrs on the track one long weekend, I never did hear one marble rolling around in there, but admitedly I was spending most of my time between 5-9.5K, mostly in 3rd or 4th, and there is no such thing as 'under light load' on the track.

Since that incident on Sunday, once I got out of the mountains the car ran fine and continues to run fine. Again this is just information on what occured, but it does have similarities to other examples of this problem I have read on this forum. I can't imagine that the situation I encountered is normal for the RX8. Maybe its just my car specifically and I am just the lucky guy, but I doubt it.
If I am enlightened by my service manager, I will certainly share my info.

Errr...no.
First of all, apex seals don't "dry out". And pinging is not caused by lack of lubrication - a sudden and violent DEATH of your motor is caused by lack of lubrication. If the apex seals were to "dry out"(I still don't understand how metals can dry), the motor would be blown in an instant, and the rotor housing/rotor would indeed be chewed to oblivion. I know from experience.
How about a more accurate sound? Marbles sound like everything. Metal on metal? Grinding, etc? This is getting stupid. I have the "marble" sound in my steering wheel buttons when cold. Think I should premix?

Its a new car (a little less than 2000 miles at this writing) and I am going to have a discussion with the service manager via phone today, but I don't expect any miracle answers. I do not believe its pinging/detonation though. I was running 91 octane and was also experiencing this problem at high altitude where the probability of running lean is unlikely.

Update from one dealership
Well, I was able to confirm that my car has had all of the proper recall work done to it via the help of a very nice service gal named Jamie at Penkhous Mazda in Colorado Springs, CO. I called them primarily because they are located in a high altitude environment and I was interested if they were familiar with the condition I experienced. She quickly took my VIN and confirmed that my car had gotten the recall work done at the dealership prior to me buying it. She did say that where they are located, they see a lot of RX8 owners commenting on power loss issues at higher altitudes. So much for fun driving on the mountain roads in NM, and just one more reason to get back home to Missouri.

I've been reading thru the various "marble" threads and have seen one other person mention the same noise I hear with mine. I ONLY hear this when the engine is cold. I can hear what sounds like "marbles in a blender" ONLY at low RPMs as the RPMs rise. The sound disappears at about 6k or so. As the engine warms, the rattling gradually decreases and eventually ceases when the engine is completely warmed up.
It's sounds as if it's coming from in front of the firewall, and if have the radio on and turned up beyond about 8 or so, I can't hear it, so it's relatively faint. I need to do some more listening with the hood up to really get a better feel for it, but has anyone else noticed this sound?

These "marble" threads just confuse me. There are a lot of mecanical sounds that I hear. But my car runs great and has for 43,000 miles. If you are having a sound that just sounds bad, take it in for service and let an experianced mechanic look at it and listen to it. Nobody can diagnose the problem on here without it being obvious or just dumb luck.

Mine according to Mazda is the heater core. It's so loud when the engine has just warmed up I just rarely go above 7k or just turn up the radio so I don't have to hear it. I guess its possible that its moisture cooking off I just don't get why every RX8 doesn't have it if its "normal".

Noticed my first marbles last night. On the previous tank afte 17000 miles of shell v power i tried chevron supreme and the car ran just as good if not a little bit better. When that was run out I went to try 76 supreme and it seemed to run the same, but for some reason sounded a little different, maybe not as high pitched, a little deeper. Was going down my road and wanted to hear the sound change so I pushed in the clutch and revved it to 9k. On its way down I heard some rattling that sounded like it was on the front undercarriage part of the car, it continued until the revs had dropped but it didn't do it again after that. Will try it out again today.

I have some marbles as well....
Seems to happen only in 3rd gear, when accelerating under high load out of a big corner. Seems to happen around 8000 rpm and upwards. Tried 2nd gear, and didn't hear it.....
Sound seems to come from under the hood (not the glove compartiment) and sounds a little bit like a mixture of marbles in a can and 'sucking through a straw in an almost empty glass (yeah i know, sounds stupid but it's the best way to describe it)' ...
I am running 95 octane, no premix (not really needed i think....)
Any ideas?

This is an excellent list so that someone like myself doesn't have to go digging through the old thread. I have number 2 MIAC. The heater core in the glovebox MIAC sound. I read in the old thread that PhantomMenace had this and took it to Mazda and they fixed it by changing a bad heater core valve or switch? I don't know which one it was but he said it fixed it.

I had the same inssue, turned out to be air in the coolent system. Dealer bleed it out and has been fine since.
I think it is great you are documenting these issues for other owners, don't let the Fan-boys bother you. They would say their cars are great even if it exploded in flames every time they started it.
Knowledge is power even when it is not good news.

Little update..... did a sort of test drive....
The sound happens just after 7000 rpm, and goes on for a second or so, and ONLY on full load. It happens in straights as well, not only in corners (that's what i thought before)
I didn't test in 1st gear, but it's there in 2nd, 3rd, and 4rd gear, probably in 5th and 6th as well. In 2nd gear it seems to be a bit less loud.
It sounds like marbles or like a crushed can but higher pitched, so i don't think it's detonation (running octane 95, temps are not high)....
Got no CEL's, and no overheating....
Could it be air in the coolant? Coolant level is fine btw...
edit: found a 'marbles' sound clip, and it DOES NOT sound like this (so it can be excluded)
http://private.tessel.pl/mazda/mazdarx8_noise.wav
edit2: Last check up, dealer replaced coolant, and i'm not 100% sure (damn memory) but i think it wasn't a problem before that (i surely would have mentioned it to my dealer).... can i bleed the system by elevating the front and just let the car idle and remove the filler cap?
