That rattling sound
.. is what they call "marbles in a can".
https://www.rx8club.com/series-i-tech-garage-22/more-marbles-can-observations-93836/ I read this thread few days ago, but I just realised what they are talking about. I had this all the time in fact. I want to know if any of you experience it as well. |
That marbles in a can is PINGING!!!!
I used to have this too.. And more when the car became leaner when i initially installed an air intake... Have u modified anything in your car? |
Says from the link I posted is that it's not pinging. Whatever that is. I only changed the exhaust, though the CAT is still on. What's the reason for the sound? You said you used to have it... do elaborate thanks.

Well... I used to have very light sounds.. prolly at ard 7000-9000 rpm.. Very very light...
THen when i swapped the air cleaner for a custom made pipe + Apex'i one.... The car ran leaner on dyno.... (I think it was that net, not sure).... And the pinging got louder but with a slight surge in power lol..... I put back the stock airbox and it dissapeared..... ===== That was Then ===== The last time i saw pinging was when i installed turbo and car was not tuned... Heavy pinging.... All that dissapeared after i tuned the car and did some timing adjustments ;) |
Well I don't know about marbles in a can, that sounds ominous, but I do love the occasional fart my 8 puts out from time to time when I'm driving her hard.....
