I know there are a million different "marbles in a blender" sounds, but i just wanted to share in case someone else is experiencing the same thing. I had been having the marbles sound at about 5.5K rpm's for the last few months and had really given up on trying to figure out what it was. Well, the other day i got a service engine light and took it by the dealer for that and a change, the dealer called me and bashed me for not driving my 8 hard enough, he said there was carbon build up and that the intake manifold runner control was stuck open. he cleaned and lubed it. I took it out this weekend to put her through the paces and to apologize for not running her hard enough and lo and behold, no marbles sound at any rpm range, in any gear.
So, moral of the story, when you think you are running youre 8 hard enough, odds are you arent, i will now be beeping daily.

hope this helps someone out.

 

Shame on you for not making her bleep enuff :D. That being said I pretty much make mine bleep everyday but me still get the marbles sound at around 7K and over range

 

Thanks zoned for the 'no marbles' heads up, and the bleeping warning. They really should put the bleeping thing in the manual, esp. for new owners. One of, if not the most important daily maintenance ritual, is the bleeping. Now you'll never forget!

 

I should mention this to my guy at the dealership.

 

I beep a dozen times a day, but the beeping marbles are still beeping there. Beep.

 

you have the true marbles. I think mine were just faux marbles.

 

Maybe they got the cause right but the solution wrong.

 

I agree with beep.

 

I used to have the "Marbles" sound too. Then I found out that the homeless man who lives in my trunk was making marble milkshakes with his blender. After I traded his blender for a bottle of Vodka, the problem sound ceased.
