Cold Start Rattle/Crackle

[ToadSmasher2K1]

I’m getting a loud crackle from the passenger side engine area during cold starts. Also during moderate acceleration I’m hearing a fluttering type sound.

Any ideas?

Exhaust leak? Exhaust gasket?

I had a similar sound but from the drivers side. Took it into the dealer and found out it was leaking around the exhaust manifold where it hooks up to exhaust pipe. Apparently was loose. Needed to be properly tightened. It was this way right from new. Somehow got missed during PDI inspection.

Same here on my 24 R. About 1,000 miles on it now and started noticing around 500 miles.

Sounds to me like the butterfly valve in the exhaust system rattles on cold start.
My suspicion is biased by my experience with my 22 Raptor having this condition but far worse. It was fixed through a Service Bulletin for a known issue at the time.

On my R, it rattles once at cold start and then only returns on the next cold start. Even with a restart after warm, there’s no rattle.

If yours is persisting, you probably have a good case for having a local ford dealership repair it under warranty. I haven’t checked but perhaps there’s another service bulletin out there.

Good luck!
