I hear the same knocking/rattling sound, but only when I turn the ignition off and it only happens for a second when the engine shuts off. Is this normal for the stock isolator? Or does that mean it's going bad and I'll soon have to replace it with a solid one? Every time I turn my car off, I cringe. However, there is no noise at all when idling.

I have 24k miles and have heard the marbles rattling sound for a while. Finally found a good time to take it dealer and have an appt for tomorrow. Hopefully they don't try to give me the run around because of the mods i have.

The dealer should and will most likely take photographs of your engine compartment, and then upload your ECU data to GM to confirm the absence of a "tune". I have a catch can, Roto-Fab, and separate reservoirs for brake and clutch. The tuning is what GM is concerned about.

Mine was replaced under warranry with mods and a tune. In my experience, be upfront and honest and you shouldn't have an issue. Print off the TSB as well to bring in.

So do they put a solid isolator on the car when they replace the parts?

I was hoping gm would have a fix for it. I did not want them to just replace with the same parts that would go bad again. If they did I was going to get the solid isolater and have them install it while they had it down.Good to know.

I honest can't remember how many it had, when replaced. It couldn't have been many because I only have just over 6,000 on it now. My wasn't having a problem. It was done because my dealer friend suggested because I told him about people on here having the issue.
