Been trying to figure this sound out, car made a loud clicking sound on freeway and then stalled. Replaced the battery, no luck, figured maybe the starter was bad, replaced it, it fired up and this is the noise it made. Took to mechanic, thought maybe flywheel came apart, pulled the transmission the flywheel was shot. Replaced clutch and flywheel, and fired it up and same sound. We seem to have traced the sound to the top back left of engine, sound like VVEL area. Here is a video any info would be greatly appreciated!
