Hey guys,
I am from germany with a 2019 Charger R/T Daytona and I also have the famous AE rattle, but I think I have found somewhat of a solution without any simulators.
My issue:
Bought a fresh imported Charger and noticed the rattle after a few days of owning the vehicle. The car was too quiet anyway so I just bought some MFER-1 simulators - it fixed by issue for now but...
I deleted my mid mufflers aswell and in germany the noise laws are very strict. To "mask" the brutal sound of the muffler delete and be able to fool the Police, I wanted a working Active Exhaust, so I deleted my MFER-1 installation - aaand the annoyingf rattle was back.
Since the re-installation of the MFER-1 is not ideal because of the noise level in germany - I went to search for a soution.
The rattle reason:
I have identified the exact thing that rattles: it is the head of the valve where the spring of the motor sits in. If I detach the Motor and Spring of the valve, and put it into closing position, I can manually "rattle" the head up and down. This is what causes the annoying rattle at 2-3k rpm - just alot quicker as you would do it manualy.
The "fix":
So here is my temporary fix that needs some more work (just discovered it today).
1. I took a regular O-Ring to seal of oil or coolingwater made out of rubber.
2. Attach the O-Ring below the Valve Head, in between the red lines is the O Ring (see Screenshot)
3. Now the valve head has waaay less of a gap to rattle
It fixed my rattle to about 90%, the 10% is still a very quiet rattle at 2k rpm but it is barely noticeable.
(please ignore the golden exhaust paste - I really tried 100 things to stop the rattle)
Here is the part that needs work:
- my O-Rings are not heat resistant, they might melt so close to the exhaust
- the O-Rings sit at the "stoppers" of full open or full closed positions. They might wear out after some days/weeks of driving with normal working valves and snap
- one O-Ring has missplaced itself because of the movement of the valve, so I had to place it correctly again
- I tried 2 O-rings but they slipped off each other
- maybe someone knows a better material or part instead of an O-Ring that still tightens the gap but is more durable?
If you have any ideas how to improve this fix so we can move it from temporary to forever, I would appreciate it.
