svtmattUT Posted February 9, 2019 Report Share Posted February 9, 2019 (edited) A few months ago my Shelby started making this rattle sound. I’ve owned it since new and it has 24k miles. I recorded it with a remote mic in the engine bay to get a better recording. I could really use your help if anyone has come across this. Most prevalent around 2k rpm or so. Has a pulley, tune, frpp tb, and resonator delete air tube. I took it in and they think it’s piston slap, they cut the oil filter open and there are no metal particles. They said, don’t worry about it and get used to the new sound.

Victor McLaughlin 56711 Posted February 19, 2019 Report Share Posted February 19, 2019 Does not sound like piston to me. Is it the same on smooth or rough road? Quote Link to comment Share on other sites More sharing options...
